Stuart, you mentioned that the PPS transmitters started having more issues in the last year or two. Do you know more about that actual timeline? My Shearwater transmitter is dated 10/18, so almost exactly two years old. I haven't had any problems with it, but this is something that concerns me.
The person I talked to said (if I am remembering correctly) that it seems like 17-19 have had more problems, and 14-16 have had less problems. Obviously, there will be SOME failures from every year. They had no failures from 2020, yet. And I'm not sure if the observation about 14-16 has any real significance. I'm not sure Shearwater was even ever selling transmitters that were manufactured that long ago, so the failure rate on those could be just as high - for Oceanic and the other brands that were selling them from back then - and it's just that none of them were Shearwater-branded back then, so Shearwater hasn't had any calls about ones from back then.
I wouldn't worry about it TOO much. But, I would make sure you have either an SPG or a spare transmitter you can swap in on a moment's notice.
I also would not worry too much about being almost exactly 2 years old. Shearwater is awesome. I suspect that even if you were a bit out of warranty and had a failure, because they know there are some issues, I would guess they would take care of you. I mean, even if they wanted to be a pain about it, the warranty is from when you bought it - which is obviously some time AFTER 10/18. Mine were dated 10/18 and I got them way less than 2 years ago.
My post was not intended to be a call to arms. Just a call to be prepared for "just in case".
