Description
SportDOG DSL-400 Deluxe Beeper with Dog Collar is an add-on deluxe beeper locator that gives you maximum flexibility with a high and low volume option, three settings for beep duration, and four different tones. The DSL-400 beeper uses a 3-volt lithium battery that provides 60-100 hours of on-time. This "run mode" beeper doesn't require a remote to use-- just slip it on your dog and set it to silent, 5-second, or 10-second beep.
