We offer repair services for older Garmin devices with a 6-month warranty.
Garmin has discontinued support for older models, offering new ones instead.
But the new T20 and TT25 models have a weak casing and a partially unresolved problem with the GPS cable.
We offer completely new ways to solve problems with your equipment!
1. Dry, rot, tear gps strap at your DC-50, T5, TT15 collars ……
It will never be a problem, if we move GPS inside. After this - High reliability and ease of repair allow these devices to operate almost indefinitely.
2. Lack of distance for some users ……
Unlike the large number of poorly understood Chinese-made antennas,
Our (R&D) company produces special UrAn (Ultra Range) antennas, which can significantly improve this devices performance. We garantee 150, 200, 250% distance for hunting antennas and 300 - 700% for seach/recovery antennas. All our products ware heavily tested and approved by our users in Russia (since 2014).
This group was created to show users how things could be better.
1. Ultra Range Antennas - +50….370% range (up to 22 miles and more)!
2. RF LNA - +50% range, aspeshialy for low sensitivity Alpha 200/300.

The weakest link in Garmin collars DC50, T5, TT15, T20, TT25 is - GPS module rubber band (with coax inside). It often breaks down due to various stresses.
The best way to fix it - is to eradicate
this rubber band. After this, collar will work right as long, as body shell is intact.
I can do it for 90$.
Also i can fix almost any malfunction in your Garmin device (50-150$).
If you are interesting in, pm or WhatsApp, or sms me.
