Planning for two dives on doubles?

[halocline]

Swapping tanks sucks and it's usually not about volume, it's about redundancy.

It’s a lot easier to swap tanks during a surface interval on a boat than it is to enter, dive, and exit wearing doubles on a simple recreational dive trip where 99.5% of the world uses single tanks.

If you feel you need redundancy on a simple recreational dive, that’s another issue.

No one said it was hard , read my post again. Also, argumentum ad numerum.

If you think that’s my issue, you clearly have never met me. Thanks for the passive aggressive snark though. SMDH

Assuming these are not unusually small tanks, there is no technical reason for their early exits. My best guess would be that they were doing some kind of training exercise.

In reality, you can get more dive time in with two dives on doubles than with equally sized singles, because you only have to worry about keeping a reserve on the second dive.

At least I got rid of my single-tank kit shortøy after getting my doubles kit as it was just collecting dust. That also meant i wore D12's when dovong with new clubmembers that dove singel and had a very high SAC. I never understood what people mean with "cumbersome doubles", as long as the D18's remain at home I dont notice a difference between the D12's and single tank rec dives in the mediterrainian, apart from D12's feelign superior in the water.

TLDR; Doubles feels better than singles, always!

I'm not very experienced yet. I think I'll probably do sidemount before doubles though. My back hurts at the thought of dubs.

There is no reason to think about it until you decide you are going to start the kind of diving the requires that much gas. When (or if) that time comes, there will be lots of options to consider, and the weight of doubles will be among the least important things to consider.

Diving doubles is so comfortable underwater, and extremely easy to acquire excellent trim, that you will forget about the burdensome aspects while on land: entry / exits and staging yourself. When I can dive doubles, I prefer to dive doubles.

Then you dive sidemount and backmount doubles feel like crap underwater in comparison.

Do I smell a rift between the doubles and the sidemount folks?

Most sidemount folks also dive (or have dived) doubles.
