Range - When manufacturers state the range of a dog tracking collar they are referring the the distance the collar can be detected over a flat and unobstructed terrain. These distances are quoted with under ideal circumstances; a clear line of sight and a fully charged transmitter. Range can be reduced with differences in terrain or a weak collar. However, all the dog tracking collars we carry are engineered to work in the toughest terrains without dramatically compromising or weakening the signal.

Radio Bands / Radio Frequencies - All Dog tracking collar systems operate on one or more different bands. Some models are capable of handling a single band while others are capable of tracking collars on multiple bands. The FCC has approved the following bands for North America - 216, 217, 218, 219, and 220 mhz. Each band is then divided into a thousand different frequencies from XXX.000 to XXX.999. If your dog tracking collar system is capable of tracking multiple collars on a single band (for example the 217 band) be sure you order collars with a large enough frequency gap to avoid overlapping. Depending on the receiver you choose you will be able to track from 1 to 1000 dogs.

Channels -  Channels refer to the number of tracking settings on a receiver.  The more channels the more dogs the unit can track .  Receivers with a set number of channels usually spread the bandwidth across the channels in increments of 10 kHz. .  Example: If a unit has 2 channels it means there are two settings on the receiver which can simultaneous track two dogs.
