The Smallest GPS Devices

The Smallest GPS Devices

When a dog gets lost it is no party.  I have discussed GPS gadgets for dogs in the past.  As technology is constantly evolving, smaller lighter units are appearing on the market.  Here are some new devices.  I have included devices that are not yet in mass production.  They are available for pre-orders.  Finally will be able to keep track of our little dogs as well as the big guys.  However, I have some concern about constant exposure to EMF (electromagnetic field) technology as there are health concerns.

Loc8tor GPS
Loc8tor GPSThe Loc8tor GPS device comes in a device with GPS (the one shown in the table above) and one without GPS.  The one without the GPS allows you to track your pet using a hot – cold type of method and that could be annoying.  The non-GPS device sells for $99.95.

  1. Pod Trackers

    Great article! I find it very interesting to compare all of the different features of various products on the market.

    Have you heard of the Pod Tracker? The Pod Tracker is the smallest and lightest GPS tracker & activity monitor on the market, offering location on-demand, escape alerts, adventure tracking, activity monitoring and many other great features which can be managed within the free app. One of the unique things that sets Pod apart from its competitors is that it is built with both GPS and Wifi technologies, allowing customers to locate their pet both indoors and outdoors. The wifi technology is very helpful in locating our little escape artists who like to wander into garages, under trees, and thick bushes where the direct line of sight with the GPS satellites may be obstructed. The Pod is easy to use, waterproof, suitable for all pets, and can be attached to any collar or harness. In addition, the Pod comes with two interchangeable, rechargeable batteries which enables you to charge one of them while the other is in use so your pet never has to go unprotected.

    I thought you may be interested in looking into the Pod for the comparison. Happy tracking!

      Hi Caroline-

      Thank you for visiting my website and for suggesting the Pod Tracker device. This article was written quite a while ago and tech is changing constantly. It sounds like a great device. The only issue I have with these devices is the concentration of EMF (electromagnetic field) exposure. I just added my concern to the article because studies have indicated that high EMF exposure on a constant basis is not healthy. I’m sorry, but I needed to edit out the link you included in the article, but I kept the name of your product in.

      Thanks again.
      All the best
