I hit 56m when searching the seabed but the wreck starts at 50m. The Tech-2 teams were using 18/45 twin 12's with an AL80 of 18/45 as a bottom stage with 50% and 100% for deco. The Tech-1 teams were using 18/45 with 50% for deco.

Bottom times were up to 40 mins for the Tech-2 and around 20mins for those who were Tech-1.

My longest dive had a 103 min runtime for 40mins on the bottom.

Hope that helps.
Cheers
Al
