For the gun dog owner in search of one e-collar that can do almost everything, there is the Dogtra Trainer & Beeper 2500. Featuring 127 levels of nick and constant stimulation with a one-mile range, the Dogtra T&B 2500 also has a remotely activated beeper/locator with a 400-yard range. The beeper/locator has three modes: run/point, point and locate, and locate only--all easily and quickly selected from a switch on the transmitter.

An LCD screen on the transmitter displays the stimulation intensity levels, plus has a three-bar battery-life indicator. The lithium-polymer batteries can be recharged in two hours. Though the 2500 might be thought of as mainly for big running pointers, remember that other retrieving breeds and any kind of spaniel can also disappear or get lost. Consider the value of an e-collar with a beeper/locator for all gun dogs.
