The receiver has 2 output jacks, allowing you to independently control launches from up to 2 compatible training devices from each wireless unit. It’s also possible to set additional receivers (sold separately) to trigger on the same signal from your handheld, achieving simultaneous “flushes” from several bird releasers. A built-in speaker horn on the receiver provides crisp, realistic audio output, with 3 attention-getting, user-selectable, preloaded sounds: Duck Comeback call; Hey, Hey, Hey command and Tone. More than 15 additional sounds are available for download from Garmin Express. Audio library includes sounds like Goose Comeback Call, Duck Quack, Heel Command, Stay Command and many more.Unit dimensions, WxHxD: 4.3” x 3.0” x 2.2” (10.8 x 7.8 x 5.7 cm)
