One dive or two?

[Line Squirrel]

If your instructor calls a dive from Peacock 1 to Olson and back two dives, you have a mighty piss-poor instructor.

Edit: Let me clarify this. I'm not talking about what you do after certification. I'm talking about an instructor that would consider this as two of the four mandatory dives for a given certification level.

I'm pretty sure most do.

I let the students count such a traverse as two dives (after at least a minimum 10 minute surface interval) but the second dive doesn't count as one of the certification dives. They end up with at least one extra dive for the class than the minimum required.

Single dive. Unless I get out of the water and take my drysuit off, it is a single dive....

Dive safe,

Mine called it one dive each time while surfacing in Olsen both times for briefing, once to set up the circuit and the 2nd dive (after complete exit) to retrieve it while back tracking. Now I still stick to what ever the puter says because I keep a down load log.

I would count as two dives, if you surface do you not then have to recalculate 3rds?

Count as one dive in my book. I was surprised that it counted as two during one of my cave class. We chatted for more than 10 min at the surface.

As far as recalculating 3rds. You don't have to recalculate 3rds if you surface. You have made it there on third so you will make it back with what you have left.

I have recalculated thirds during dives without surfacing (not even in the cavern) and it always counts as one dive in my book.

If I don't take my tanks and get out of the water then it's one dive.

And that's where opinions differentiate. If you surface and count it as a second dive, you should recalculate thirds, as it is a second dive.

But to each his own.

I don't.

Personally, if I haven't reached thirds yet, or am right at thirds, I'm going back the exact same way and downstream, I would not recalculate thirds.

Given those parameters, surfacing would not be any different than turning a dive, from a gas management perspective.

That said, there is no denying that your way would be the more conservative, but I don't see the need.

If I am making a traverse, and not changing tanks or even getting out of the water, its one dive. If I am just sticking my head up in the sink for a quick chat, its still just one dive.

For the record, making a traverse and staying above 5 feet in a sink long enough to reset the computer sounds a little hokey. I have several 2 hour dives in my logbook from long penetrations, and I enjoy those nice long dives and expect to make many more.

Personally, I won't be surfacing just to double the number of dives I did today.

As far as recalculating 3rds. You don't have to recalculate 3rds if you surface. You have made it there on third so you will make it back with what you have left.

Better think again. If you made it in on thirds, and don't re-calc. You will be planning the return trip on half of your remaining gas.
