Good Performance So Far with Occasional Handheld Connection Issues
November 26, 2024
I have used the collar a handful of times and performance appears good. That said, time will tell how good. I have had some connection issues with my Alpha 200i which have been resolved by rebooting the collar, the handheld or both and I had one instance where I had to remove and re-add the collar to my 200i to get it to connect. Once the collar is connected, it seems to stay connected to the handheld.Ironically, I hunted with a friend one day who was also having connection difficulties with another Garmin system at the same time as me--but he was using completely different Garmin products. I don't think he ever got it resolved.
Pros
Good, trouble-free tracking.
Cons
Intermittent connection issues with a known working 200i.
