Garmin Astro 900 + T9 Collar COMBO

Garmin Astro 900 + T9 Collar COMBO. The Astro 900 is the newest in Garmin’s well-established Astro tracking line. With a 5-mile range and the ability to track up to 20 dogs when connected to the new T 9 collar, as well as an increase in the number of channels on which your system operates, you’ll spend more time enjoying the hunt rather than fighting your device. Interference from other devices can be a problem for many hunters, but with the Astro 900, you’ll reduce this problem significantly. The Astro 900 is a step up from previous Astro models, featuring a 900 MHz FHSS signal that makes the unit fully approved for use in Canada and the U.S.
