Findster Duo+ is an innovative GPS pet tracker that comes with no monthly fees. It was developed by Findster Technologies, a fast-growing California-based startup launched in 2015. It allows for real-time location and activity tracking, boasts a communication range of up to 3 miles, and does not require cell coverage, so you can keep track of your pet’s whereabouts no matter where you are.

Findster Duo+ hit the market in 2017 as an upgraded version of the company’s already well-known Findster Duo tracker and it has been generating quite a lot of attention ever since its launch. In this Findster Duo+ review, we will explore its key features in greater detail and help you discover whether it is the kind of pet tracker you have been seeking.

How Findster Duo+ Works

Findster Duo+ GPS pet tracker comprises of 2 devices, that is, 2 modules – the pet module to be attached to your pal’s collar and the guardian module you should keep by your side. The pet module is equipped with GPS that communicates the pet’s location to the guardian module. In turn, the guardian module is connected to your phone via Bluetooth and allows you to view your pet’s activity and location information in the dedicated Findster app.

While this pet tracker performs multiple functions, all of which we will describe in the following sections of this Findster Duo+ review, its primary role is to help you easily track your pet in real time. It shows you the exact location of your pal, allows you to follow him or her via Findster app, and sends notifications as soon as your buddy leaves the safe zone, so you can find your pet immediately.

Like we said before, Findster Duo+ does not require cell coverage in order to work. It employs Findster Technologies’ proprietary MAZE technology. It is a unique communication protocol with frequency in the sub 1 GHz ISM band, which is in compliance with the FCC and CE directives. The MAZE technology functions independently, without the aid of telephone companies, which is why it works anywhere and everywhere. This independence is what allows this tracker to be 100% fee-free.

Findster Duo+ Design

Findster Duo+ pet and guardian modules feature a rather sleek design. They come in the shape of a rounded rhomboid with pleasant shades of blue. The pet module comes with a simple, clasp-like collar strap attachment mechanism while the guardian module can either be attached to your keychain or you can carry it in your pocket.

The modules are incredibly lightweight, so both you and your pal can carry them without even noticing they are there. A single module weighs just 1.76 oz., which amounts to 50 grams, the weight of an average kiwifruit.

The pet module is designed to fit both small and large dogs and cats. With a height of 2 inches, width of 2.1 inches, and depth of just 0.5 inches, it can easily fit any collar.

Findster Duo+ Technical Specifications

It is time to discover what you can expect from your Findster Duo+ pet tracker in terms of water and impact resistance, battery life, GPS precision, communication range, and other important technical aspects.


According to the manufacturer, Findster Duo+ is tougher than the old Nokia 3310. It is highly durable, so you do not have to worry about it getting damaged easily if your pet gets restless or if you drop your module.


Another highly useful feature of this tracker is that it is waterproof. It can withstand immersion of up to 3 feet of depth, that is, 1 meter, so your pet can even swim while wearing the tracker.


Findster Duo+ comes with a rechargeable battery. In comparison to its predecessor Findster Duo, Findster Duo+ comes with an extended battery life. Its battery can last for up to 5 days, depending on use. With live tracking on, the battery usually lasts for 12 hours.

Findster Duo+ Technical Specifications

Communication Range

Previously in this Findster Duo+ review, we said that the device has a communication range of up to 3 miles, that is, 4.8 km. However, it is important to note that the communication range can greatly vary depending on surroundings. It can be even greater than 3 miles in open spaces like beaches, national parks, and urban squares, with the record so far being 5 miles (8 km). In urban areas with a lot of tall buildings, the range may significantly decrease, but if the connection drops, the modules will attempt to reconnect until successful.

Distances Between Devices

While the guardian and pet modules can communicate within a range of approximately 3 miles, the distance between your smartphone and guardian module should be significantly smaller. You should always keep your guardian module no more than 2 yards away from your smartphone in order to allow for a Bluetooth connection to be established.

GPS Precision

The tracker features high-precision GPS that lets you easily locate your pet. With this GPS, the average error is just about 5 to 10 feet (1.5 to 3 meters).


Findster Duo+ pet and guardian modules come equipped with a LED light that allows you to track your pet more easily in the dark and provides important information about the device. The LED light lets you know if the modules are not paired (white light), if they are turning on (green, 3 times blinking) or off (red, 3 times blinking), if the battery level is good (green) or if the battery is low (amber), if the device is charging (amber), if the device is charged (green), if Firmware update process is running (blue), and more. You can even choose an identification color for pet modules, so you know which pet the module belongs to.

App Compatibility

Findster Duo+ app boasts great compatibility. It can work on virtually any smartphone. It was not designed to be used on tablets, but it can still work well on tablets that meet the minimum requirements, including Bluetooth 4.0+ (Bluetooth LE) and GPS. You can use it on iPhone 5+, iOS 9+, and Android 4.4+.

Findster Duo+ App

Findster Duo+ app is your assistant that provides all the information you need on your pet’s whereabouts and activity. It provides a map that tells you the distance between you and your pet and shows you the way to your furry friend. It allows you to set desired ranges and sends automatic notifications when your pet is out of range.

Findster Duo+ App

On top of that, the app allows you to easily keep track of your friend’s activity. It tells you how much time your pet spent walking, the distance he or she walked, measured in miles and paws, how much time your pal spent resting, and how many calories he or she burned. To make tracking more fun, Findster app allows you not only to view your pal’s activity stats but also compare them with stats of other Findster users’ pets with the fun Leaderboards feature. Plus, you and your friend can earn badges by reaching activity milestones and compete against other Findster users, which can be an exciting incentive to spend more time walking and having fun with your pet.

Findster app further provides useful reminders, for example, if your pet has not been walked yet. You can keep track of all your pets within the app, without any extra charges.

Findster Duo+ Features

Findster Duo+ is a feature-rich tracker that offers a multitude of handy tools, from true real-time tracking to remotely monitoring your pet’s location and activity with the help of your friends and family. Let us see exactly what kind of helpful features this tracker provides.

True Real-Time Tracking

Unlike many other pet trackers that monitor your pet’s activity and location in real time but provide belated notifications, Findster Duo+ provides true real-time tracking, with notifications arriving instantly and all information available immediately in the Findster app. This is one of the major advantages of this tracker and one that makes it genuinely useful when your pet roams out of sight.


Findster Duo+ does not only allow you to monitor your pet’s current location and activity, it also provides a detailed history that allows you to view past walks and locations at any time.

Activity Tracker

Not only useful when your pet is out of sight, Findster Duo+ can help you make sure your pet’s daily needs are met as well. With its activity tracking feature, it allows you to view all key information about your pet’s activity, so you can be sure that he or she has met the daily goals and engaged in enough activity to stay happy and healthy.

Findster Duo+ Features


With the device’s built-in radar, you can always keep track of your distance from your pet. Distance data is constantly refreshed and you can easily locate your pet by following the handy map available in the app.

GPS Fences

GPS Fences is a particularly handy feature that comes in 3 forms: Virtual Leash, Safe Zone, and Danger Zone. Virtual Leash is a fenced circle centered in your position and it moves as you move. You can set the desired radius, no smaller than 55 yards, and get an automatic notification the moment your pet steps outside the given radius.

Safe Zone is stationary and fully customizable and it represents an area within which your pet can freely roam. If your pet goes beyond the given area, you are immediately notified.

Just like Safe Zone, Danger Zone is a custom-defined area, but it represents an area where your pet should not go. If your pet enters this area, you receive an automatic notification.


Due to Findster Duo+’s interconnectivity, you can share access to your pet’s location and activity with your family and friends. This allows you to track your pets remotely – by having someone close to your pet sharing your pet’s location and activity information with your Findster account. However, to take advantage of this possibility, you need to be connected to the Internet.

Findster Duo+ Coverage

Thanks to the unique MAZE technology developed by Findster Technologies, Findster Duo+ can work anywhere on the globe, even in the most remote areas. You and your pal can be off-grid, as the device does not require cell coverage or a SIM card. You just need to attach the Findster Duo+ pet module to your pet’s collar and you can take your four-legged friend with you wherever you go, no limits whatsoever.

How Much Does Findster Duo+ Cost?

You can purchase a single Findster Duo+ GPS pet tracker for $149.99. If you purchase 2 devices, you pay $199.99. If you purchase 3 pet trackers at once, you pay just $249.99 in total for all 3 devices and save around $200. As stated previously in this Findster Duo+ review, there are no monthly fees; you only pay for the device.

Findster Duo Cost price

Each tracker you purchase includes 1 pet module, 1 guardian module, and 1 charger. All orders come with free worldwide shipping. It is good to know that Findster Duo+ GPS pet tracker comes with a 30-day money-back guarantee and a 1-year warranty.

  1. Marc Bailey | January 28, 2021

    Ordered two DUO+ trackers. One works perfectly well while the other unit does not connect to the cradle correctly and also did not record anything like accurate GPS recordings. I reported this to them after 2 days of delivery. They are refusing to send me a replacement unit and are blaming it on firmware. Strange how one device works on the same firmware.
    Looking at other reviews it seems the message is clear… shoddy hardware and POOR CUSTOMER SERVICE. Buyer beware

  2. John Ramsey | January 15, 2021

    Got the Findster Duo as a Christmas gift 20 days ago. Now the pet module will not turn on. It will charge, but not turn on. The troubleshooting function of Findster’s website is terrible and you can’t talk to anyone in customer service. It was fun for 20 days, but now it will not function!

  3. Meagan Grant | January 5, 2021

    Purchased the Findster tracker upon returning home from looking for my dog who got out of my backyard. It was delivered today – right out of the box, the guardian module won’t turn on…after reading these reviews, I worried they won’t refund me.
    I’m honestly thankful it was broken when I received it, so they can’t say it was wear and tear or user damage.
    Also, takes forever to charge…
    Garbage – would give 0 stars if possible.

  4. Margaret Cooze | December 16, 2020

    Fiddly to turn on and off and worse to charge.
    Connection is lost every few minutes even in an open rural area.
    Modules are cheaply made and this isn;t worth the money.

  5. G. v U. | December 5, 2020

    Like many others I’d give this 0 stars if I could. Why? Because it’s expensive, clearly not well-built, and unreliable in all but the most basic situations. It needs constant troubleshooting and Findster take no responsibility and always prefer to blame customers for their product’s failure and winding them up. Avoid at all costs.

  6. Ursa Major | November 27, 2020

    What an awful corporation! Oversold the product & kept changing shipping & delivery dates. Took weeks to get the product. When I left a poor review on a website, they tried to bully me & blackmail me to take it down. They had me harassed by a rude, misogynistic employee named José. If I had known they were out of stock I would just have moved on to the next available service. Instead they manipulated me into thinking I was about to get the product, which miraculously appeared when I gave them a bad review.

    The upshot: no idea how to give good customer service. Fly by night company. Probably won’t be in business very long.

  7. Bronwen Mackay | November 25, 2020

    Bought this because it appeared to tick all the boxes, what with the promised fences and “leash”, and the relative neat size.

    The unfortunate reality is that-
    1) The pet module’s mount to the collar was so poorly designed that it was lost.
    2) The pet module’s button doesn’t do anything (therefore making the module nigh-on impossible to operate). This, despite the fact that the unit has been little used due to the unreliability of the units.
    3) The connection between it and the guardian modules are lost, thus ending the walk (effectively losing the dog into the bargain).
    4) The company have access to all your personal data and are not afraid to share it in public if it suits them.
    5) The “customer service” is aggressive and utterly lacking.

    Conclusion: do not buy, if you value your pet, your money, and your privacy/security.

    • Arslan | January 14, 2021

      Thank you for the honest review. Seems like they are rating themselves to appeal to customers.

    • Nathalie | February 14, 2021

      Buddy, my german sheppard and I, we Love Findster!
      Couldnt leave without

      We leave on a 100 acres farm on the country side of Ottawa, Canada
      Findster always let me know when Buddy is going too far away… then i can call him on track him on my phone. Sometimes Findster give me false alert, but not often. And most importantly Findster always tells me if Buddy leaves

      I also use Findster at my RV in the wood. Its a bit more difficult there in the forest
      But if Buddy goes too far, i know in which direction and follow him with my phone
      When the gps get the signal again it connect and i can see where Buddy went

      I found the battery wouldnt last a full day on intense tracking but at first i bought two module thinking i was gonna use it on my siamese cat. I end up using both mostly for Buddy

      A month ago i misplaced one pet module, it was power off so i couldnt find it
      I missed it so much that after about that, a month , i ordered another pet module

      and now Buddy is never on the leash again and spend all his days Freely outside .

      I have been using Findster since december 2019, 14 months ago
      And i couldnt leave without
      Best thing i ever got for my dog
      So yes maybe Findster is not 100% perfect but you can go around its flaws
      And it is not a monthly membership!

      I recommand it 100%


  8. Saarah Mata | November 3, 2020

    Had some trouble at the start but the customer support worked tirelessly to help me figure out what I was doing wrong!! So grateful for their patience!! Wish more companies cared about their customers like this!!

  9. Max Stevens | November 3, 2020

    I usually let my cat roam outdoors but he was starting to take longer and lnger to come back, so I became worried and started to keep him inside more. Well needless to say he was not very happy with that.

    Since I got the Findster, I can let him roam freely once again, as I can keep track of his location from my phone. I’m happy to know where he is, and he’s happy with his freedom! I was afraid that it would be too big for him, but the modules are quite light and he doesn’t seem to mind… I guess he realizes he needs to wear it to be able to get out!

  10. John Beanblossom | October 25, 2020

    difficult to charge, pet module comes off mounting bracket when my dogs rolls in grass. lots of disconnection problems as reported in other reviews.

  11. James Feerst | October 19, 2020

    Amazingly poor magnetic charging system. Almost never connects and you never know when it is charged. Green light flashes and then nothing. So you don’t know if it has successfully charged or not.

    Also, the documentation and support are poor. The videos are too small to be of any use.

  12. Rum Diego | October 4, 2020

    I own this product for 2+ years. 3 dogs, one can be tracked the other two are either off or disconnected – when they aren’t.
    The one dog somehow lost the halter for the module, where to get a new one?
    No alarm when they breach the fence – that is why I have this!
    One gets away and the GPS folds – mind you on 120 acres rural lanmd one ought to be able to track a dog via GPS – Findster can’t.
    It was a lot of money for a product which was very promising and delivered almost nothing.
    I have to reinforce phhysical fences because the virtual ones fail almost daily.
    Thank goodness my dogs know how to get back to the house. I could not find them with this product.

  13. Douglas Goyette | September 14, 2020

    This company shipped me junk that wouldn’t turn on, they gave me the run around for a week on returning it then they sent the wrong shipping Labels because their costumer Service doesn’t care about you…. I am out 220 dollars now because I had to pay to ship IT AND THEY STILL HAVE MY MONEY MORE THEN A MONTH LATER1


  14. Kat C | September 10, 2020

    What a con. Be careful as when you buy this they automatically sign you up to a monthly subscription using your card details. You only realise if you see it on bank statements. Misleading and poor business.

    • Robin Peterman | December 31, 2020

      What monthly subscription? I thought there was not monthly subscription for this.

  15. Shanra Ingleman | August 27, 2020

    Dealing with this company was an awful experience from the very start and I would DEFINITELY NOT RECOMMEND dealing with them at all!

    I was interested in this device for my cats and ordered without realising the TERRIBLE BATTERY LIFE of this item. I messaged them immediately (approximately 5 minutes after plaving the order) because their policy stated that any orders cancelled prior to shipment would be refunded in full.

    They messaged back saying the order was cancelled and I’d get my full refund back. However they dont make money that way. They still sent the item SEVERAL DAYS AFTER it had been cancelled in order to force me to cover the exorbitant postage costs. I didnt even open the package upon receiving, I just sent it straight back and they refused to refund me in full as they initially promised.

    This is a SCAM company that LIES and MANIPILATES in order to take the money of consumers. The product is no good, but the customer service is apalling and they do not care about you at all!


  16. Jeremiah F. Harper | August 26, 2020

    I’ve used the tracker a couple of times since I got it and I’m already a fan, it’s fun to see Kaja move in real time on the map when we go to the dog park! It’s a good way to keep up with her adventures and make sure she doesn’t stray too much.

  17. Spock's Mom | August 22, 2020

    I purchased the Findster Duo for dog Spock several years ago. The charger is horrible. It links the modules to the charger via magnets, obviously too weak to keep a connection. After repeatedly reconnecting to the charger, it fails EVERY time. I just pulled the unit out of storage to attempt to charge again yesterday and it’s still not charged after reconnected 20+ times in the past 2 days.

    Also, there are two very small bumps on each side of the mounting device (4 total bumps) to attach the unit to the connector on collar, one broke off immediately. I don’t want to lose the tacker so I have to re-duct tape the unit to the collar every time I need to charge it!

    Poorly made and customer service is terrible, take forever to respond IF they respond at all.

    Potential buyer BEWARE. There’s got to be a better tracker than the Findster Duo.

  18. Glen N. | August 19, 2020

    My cat dreaded putting it on. I felt bad. It was like handing a bowling ball to someone in a pool of water. Problem is that it wasn’t reliable. My cat would leave the house (and even my wife, when testing it) and it would suddenly and inconveniently disconnect. This happened at least 6 times a day for the 2 days I used it.

    Worse of all, the company would not pay for return shipping. On my third request, after telling them that the company provides return shipping labels and quoting their website, the rep Jane Jonson said, “Glen, it also says ‘unless our team says otherwise’. For your country, we do not provide return labels. Please proceed as instructed on the email you received.” So, I do not recommend that North Americans try this product unless you want to pay the return shipping once you find out it doesn’t work as advertised.

  19. Bryan | August 14, 2020

    Do not buy for a rual area, or period. Waste of money. Charger worked for like a week, the magnet aspect is silly, takes 5-10mins just to get both to start charging if at all. Battery life for the tractor could be better, dies too quick in my opinion. More than often the green light comes on signifying its charged and wont be charged. Tractor was damaged in a week or two in our rual area, not durable at all, cheaply made. As far as tracking abilities, works moderately, will take you to a gernal area where your dog may or may not be. I’d rate this product at 0 stars if possible, basically useless.

  20. Douglas Goyette | August 13, 2020

    I ordered this hoping to be able to trach my dog… once I it arrived it wouldn’t turn on… from here on out it was a nightmare dealing with the support. They have no phone lines and wanted me to take pictures and videos of me trying the stupid stuff they wanted me to try for something that wouldn’t even turn on. why would i even want the junk if i had to do all this stupid stuff to get it to work? once they said I could return it after many painfully dumb emils with them they sent me a email that was hard to get the documents they sent off it. then i take it to ship the junk that never worked in the first place back i have to Pay for SHIPPING!


    I would give a zero if it was a option…
