Rescue Mode
The Rescue Mode increases the amount of time before a collar battery dies. This allows more time to find and recover the dog. This mode can be activated automatically or manually. When it is manually activated, the collar’s update rate will drop to every 2 minutes to ping the ALPHA handheld to extend the battery life. The Rescue Mode stays on until it is turned off. When the battery of the collar drops to 25%, it will be activated automatically.

High-Sensitivity GPS/GLONASS Receiver
The Garmin TT15 mini collar has built in Standard GPS satellite receiver as well as the GLONASS satellite receiver. The GLONASS is the Russian Navigation Satellite System which has 24 orbital satellites. It is the second alternative navigational system in operation with GPS. It means this Garmin TT15 mini collar is able to receive 24 more satellite signals than other GPS dog tracking collars. It is very unlikely that this TT15 mini collar will lose the signal. The GLONASS helps you to locate the dog much quicker and has much better signal strength even in heavy cover.
