Hi,
I was wondering if anyone has experienced a similar issue or has any suggestions.
My wife and I have completed around 100 dives using the Garmin Descent MK3i with the T2 transmitter, and until recently, we had no connectivity issues. However, starting around February 2025, we began encountering a recurring problem.
On the surface, both of our watches successfully connect to our respective T2 transmitters—I can see both mine and my wife’s, and she can see both as well. However, once we descend, I consistently receive a “no comm” message for my T2, though I can still see my wife’s tank pressure. My wife, on the other hand, gets a “no comm” message for both T2s.
When we return to the surface, our watches reconnect to the T2s, and we can view our tank pressures without issue. This pattern repeats with every dive—losing connection underwater but reconnecting at the surface. Typically, I can see my wife’s T2 but not mine, while she sometimes sees both transmitters and other times none at all.
For reference, our watch firmware is up to date (version 19.49), and the T2 software is on version 4.0.
I submitted a support request to Garmin last weekend but haven’t received a response yet, possibly due to the President’s Day holiday. In the meantime, I’d appreciate any insights or suggestions you might have.
