The Garmin Delta Upland™ Handheld is a replacement handheld for those who are serious with their upland hunter and bird dog trainer. This handheld remote by Garmin has a simple push-button design and an easy-to-read LCD display. When paired with a Delta Upland dog device and beeper (sold separately), the Garmin Replacement Delta Upland Handheld serves as a "virtual leash," controlling up to 3 dogs â€” regardless of the breed or coat thickness â€” at 1 time, up to 3/4 mi away, and features a beeper control button so you can instantly locate your dog, or easily switch the beeper sound on or off. This remote is ergonomically-designed to require only 1 hand to operate with 3 front "action" buttons for continuous and momentary stimulation, tone and/or vibration. With 5 correction configurations, the trainer switch easily between dogs and make immediate corrections or changes when necessary. Like all Garmin outdoor products, the Garmin Spare Delta Upland Remote is designed to be effective, rugged and waterproof (IPX7) and has a long-lasting rechargeable, lithium-ion battery.
