Dogtra's new 2500 T&B (train and beep) is a combination stimulate and locate collar that uses the traditional wide-range of power settings (rheostat knob controlled), from low to high, with a nick or constant impulse. Its beeper runs in three different modes (run and point, point only, and locate only) with three adjustable volume levels that can be set up to 250 yards. Other cool and unique features are Lithium Polymer batteries with a two-hour "quick charge" capacity, an LED battery-life indicator and an illuminated LCD screen that indicates the exact level of stimulation. The 2500 T&B is also available as a two-dog system (2502 T&B). Contact: Dogtra, Dept. GD, 1250 E. 223rd Street, Suite 119, Carson, CA 90745; (310) 522-1800; www.dogtra.com
