Fix for Wi-Fi Updates
Some users experienced problems when attempting to update their T20 or TT25 collars via Wi-Fi. The v2.19 update corrects this issue, making wireless updates faster and more dependable. Now you can keep your collars current without the extra hassle of a wired connection.
For hunters and dog trainers, keeping your Garmin collars up to date is critical for consistent GPS tracking and training performance. By fixing the Wi-Fi update process, Garmin has made it easier to ensure your T20 and TT25 dog devicesare always ready before a hunt, training session, or competition.

The T20 and TT25 collars feature longer battery life, improved GPS reception, and a slimmer design ideal for upland hunting and hound work. Through our LCS Trade-In Program, you can trade in older Garmin collars and receive credit toward a brand-new T20 or TT25. It’s the easiest way to upgrade your Garmin system while saving money.
