Tri tronics transmitter and collar repair

[20guage1]

Is there any individual or company that services the old g3 tri tronics units? Collar clinic has batteries , but will not service the units that I have, I know some replacement parts can be obtained on this site, or ebay. However I would like to have my units refurbished. Thanks in advance for any information.

800-800-1020 garmin still services g-3 units & collars, but it's pricey if you need much done.
