DSL 400

Choose from high or low volume, three
beep-duration settings and four tones. The
Model DSL-400 uses a 3-volt lithium battery
that provides hundreds of hours of "on" time.
It even has a battery-check function so you
won't get caught with a dead battery. The
lightweight beeper fits most 1-inch-wide
collar straps, so you can put it on or take
it off as needed.
