The SportTrainer 575 is designed for field training and hunting with close-working dogs. Featuring an easy-to-read OLED screen, you can view the selected dog, static stimulation level, and battery status with just a glance. This, combined with large Dog 1 / Dog 2 buttons to easily toggle between dogs, makes the SD-575E especially suited for multi-dog hunting situations. Using DryTek technology, this rugged system is waterproof and submersible to 25 feet, allowing it to perform in any weather or terrain.
