Garmin TT25 Extended Battery Pack

Garmin TT25 Collar with an extended battery. Available in the standard and mini flex band. 

This Garmin dog collar comes with the standard flex band (regular size).

This extended battery pack is user-replaceable and allows up to 136 hours using dynamic update rate. 

Built for Long Runs and Harsh Conditions

When you run hounds for days, battery life dictates your success. The Garmin TT25 extended battery pack gives you up to 136 hours of continuous tracking. This collar utilizes a dynamic update rate. The device automatically adjusts its ping frequency based on your dog’s movement to conserve power. You will not have to worry about losing connection during a long weekend in the woods. Built for mud and deep water, the unit is fully water-resistant up to 10 meters.

The rugged exterior housing takes the abuse of hard-running dogs. When you finally get back to the truck, recharging is straightforward. The device powers up quickly using a Garmin USB cable type A to type C, ensuring you are ready for the next drop.

Handheld Compatibility and Collar Fit

Do not guess if your gear will communicate. This collar pairs seamlessly with a wide range of Garmin handhelds. You can easily upgrade your dog's equipment without replacing your entire system.

• Compatible Garmin Handhelds
• Alpha 100, 200, 200i
• Alpha 300, 300i
• Astro 430
  
  

The standard flex band accommodates most pointing dogs as well as full-sized hounds over 35 pounds. If you run beagles or smaller terriers, contact us about swapping to the mini flex band for a secure fit.

Selecting the Right Antenna

We offer customized antenna options to match your terrain.

• Standard 18-inch antenna: Ideal for maximum range in open country or fields.
• Compact 14.5-inch antenna: The preferred choice for hunting dense brush and heavy briars. It prevents snagging without a significant drop in distance.
