Hi,
I'm having some oring issues with my Descent T2 Transmitter and was hoping I could get your help, since Garmin Support is literally ignoring me.
T2 bought at January '24, made 50 dives since then all with transmitter attached on a short HP hose using the supplied flow restrictor. Unfortunately, the T2 uses non-standard size of the spool and the orings making it extremely hard to service. My problem is not only with the size, but with the frequency of failures of this oring. I had already 3 failures, one of which was unfortunately pretty deep and required emergency ascent.
I have not identified any potential reasons for my orings failing - I've lubricated them with proper silicone grease before installation, they sit inside a T2 unit, so nothing external can be twisting/scratching it etc. First one lasted like.. 20 dives, second 10 and third not even 5.
Here's a result of the failed oring, for curiousity ;-)

here is the specification:

As you can see, the spool uses:
Large Side
- Size: Internal Diameter 3.30 mm x 1.00 mm
- Material: 70 Durometer Neoprene
Which is nearly impossible to acquire and Garmin only offers a full set of flow restrictors for ridiculous price.
Should I suspect it is transmitter, spool or something else damaging my orings?
Regards,
Adam
