CONSIDER YOUR TRACKING NEEDS TO FIND THE BEST GPS DOG TRACKING SYSTEM.
Are you going to use the dog tracking device as an added security for the family dog? If so the Zoombak system is directed more towards your needs. If you need hunting dog GPS tracking, this most likely will not be the best dog GPS collar for you.
EVALUATE THE DURABILITY OF THE DOG GPS COLLAR CAREFULLY.
This is the number one concern for hunters that are looking to track their dogs. Look for a fully waterproof construction. Not just a dog GPS that can handle getting wet. A hunting dog will put the device through everything, the best dog tracking GPS should be ready for it.
CONSIDER THE LOCATION OF THE ANTENNA AS WELL.
GPS dog collars can develop issues with signal if they antenna is down at the dog's chest. An antenna that is able to stay near the top of the dog lends itself to a stronger signal. Keep this in mind as you review dog GPS collars.
