Garmin Alpha 300i Handheld GPS Navigation 3.5 inReach 20 dogs 9 miles 18 stim 50h

Dog Tracking Handheld

The Alpha 300i is a dedicated GPS handheld built for hunters and trainers who need to monitor multiple dogs in the field. It pairs with compatible collars to track and train up to 20 dogs simultaneously from distances up to 9 miles away. The unit provides location updates as fast as every 2.5 seconds so you always know where the pack is. An active subscription unlocks two-way messaging and interactive SOS alerts through the 100 percent global Iridium satellite network.

Sunlight Readable Touchscreen

A vivid 3.5 inch capacitive touchscreen remains clear in bright sunlight while physical buttons allow quick, one-handed control of training functions. The button-operated layout lets you deliver 18 levels of stimulation, tone or vibration to a paired training collar without looking away from the dogs. Preloaded TopoActive maps, satellite imagery, a 3-axis compass and barometric altimeter support navigation across unfamiliar terrain. Wireless connectivity delivers updated mapping content directly to the device when linked to a network.

Subscription Dependent Features

Satellite messaging and SOS capability require an active inReach subscription and are subject to jurisdictional regulations that may restrict use in certain areas. Battery life reaches up to 50 hours on a single charge, limiting the length of continuous trips without recharging. Tracking range and update rate depend on the specific collar model paired with the handheld. Premium mapping content also requires an Outdoor Maps+ subscription for ongoing access to updated map layers.
