Descent T1

I bought Mk2i and T1 several weeks ago for me and my brother
During all our divings there were discrepancies about 20 bar between tank pressure values on screen of MK2i and mechanical gauge.
Is it okay? And which values is more accurate (T1 versus gauge?)

Interesting, I had the same experience. My T1 was consistently about 300 PSI below my pressure gauge.

Interesting. I was on a boat last month, and my Garmin AND my pressure gauge were always 20 bar below every body else's values for the same tank. I assumed that mine was correct and theirs wrong.

Just came back from a week of diving and on every dive the MKSi was about 300-400 psi below my SPG. I checked it against other SPGs with same result. Is something not set right or do I just need to call Garmin.

Just thought I would provide an update. I spoke to great tech person at Garmin who agreed that our units should be spot on with an SPG or at most +-50 psi. They are sending me a new unit to replace mine... no hassle.

Did the new transmitter work? i have exactly the same issue

I have only been able to test on dry land but yes, the new unit is now within maybe 50psi of my gauge, so much better.
