Let me first explain the use case. I (and some fellow cave explorers I dive

form. No attached divecomputer to the mCCR, but only some analog po2 devices
to fly the unit. This obviously results in no logging from po2 sensors. I
use a OSTC3, and most of my buddies some Shearwater divecomputer. As I am
(at this point), not aware how a Shearwater handles this use case, I
consider only an OSTC3 for now.
Hi Jan,
Could you elaborate on your dive computer use and setpoints?
I also dive my SF2 in manual mode completely but I have a fully eccr
unit with a Shearwater controller.
I "simply" use a setpoint of 0,7 as safe net and I fly the unit manually.
How is your OSTC3 set? Do you need setpoints for deco calculation?
My question is not really Subsurface related (ATM I don't get how a
Subsurface mod will help) so, if you prefer, we could continue off
list.
Bye
Lets first continue on list. Dirk will definitely tell us when its not
wanted on list :-)
The OSTC3 has 5 so called fixed setpoints. During the dive you manually
have to manually set the wanted setpoint for the remaining of the dive
(when diving it without sensors attached). So yes, I do that for deco,
and sometimes like to play with that (as we have sufficient time at
deco) to see the changes in the deco profile, and even sometimes match
with buddies. Why expose to 1.6bar po2 when a 1.4 would get me out at
the same moment as my buddies. Remember that I am talking about cave
diving, where your depth profile is dictated by the profile of the cave;
so automatic switching based on depth is not very useful.
Your use case is definitely different, as you have measured po2 values
in the Shearwater controller, which drive your deco calculation.
best,
