Rebreather World - View Single Post - setting pri and sec handsets differently???

**Dsix36** · 9th December 2007, 13:26

Yesterday I did a dive of 2hr 15min at an average depth of 68'. I have always run my GF at 10/100 and stayed alive (awfully tired and my knees ached that night).
Yesterday I ran my primary GF at 25/85 and my secondary at 10/100. At 1hr 36min into the dive my primary was showing 4min of deco (first stop at 20') and the secondary was showing 38min (first stop at 50').
I set the dil to 21/35 on both handsets. I checked the setting at depth and after the dive. Everthing seems to be right.
Anyway I did the longest deco to be safe (not tired or achy knees last night), but I can't believe that these are right.
I thought that the first number in a GF would put the first stop deeper as the number was smaller. Is this not correct? It seems to me that 10/100 should have had deeper stops and got me out of the water sooner than 25/85.
Any help or advise will be appreciated. I am not a rocket scientist (yet) but I thought that I understood the principals of GF's
Help, I am sooooooo confused.
