I am always searching for the best beeper to fit my needs and the correct combination of collars that will work best with my hunting dogs.
Some beepers have remote controls that work in combination with an electronic training collar. The transmitter allows you to turn the beeper on an off as the cover changes or as your dog ranges out of your sight.
