Perhaps I've missed something, but in every and all computers - D3, D4 and all of those famous .... I can't find one very important option - disabling automatic recording while doing dynamic apnea. What I really need is to start and stop and start and stop - MANUALLY - recording my training session in pool, when sometimes depth does not automatically forces start of recording of dive as a dive, while I'am already at least few seconds under water. During my 50-75 m dynamic training my depth ranges from 0.7 to 3.0 m, which makes all of those famous computers ... you know what. I dream about having freediving computers that is able to record - WITH MY HELP - my training session in pool also, not only while going deeper and deeper ... Perhaps I want too much. But CASIO, so far, is doing its job. Exept recording. When they allow for it .... imagine. Or maybe some tips from other folks that do 80+ percent of their training in pool ... please.

If you turn off the dive computer on the D3, you can use the stopwatch (up or down). I missed this feature until recently.

Thx, Bill.
However, my old good Casio DW290 T has stopwatch, too. What I was writing about was to have an option of transmitting WHOLE (diving time, surface time) session to my PC or PDA, compare it to my plan - analyse training session, to make it short. Having a stopwatch priced at that level as D3 is seems to be a bit ... you name it ;-) Since most sensors in diving computers have to react below the level of 0.9 m, I need to start and stop it manually. And I need it to be recorded, as while in automatic mode - be it scuba, free or gauge ; -) I am not a microprocessor designer, but it shouldn't be so difficult to achieve. Mike

Mike, not sure about D3, but my Suunto Mosquito worked rather reliably for dynamics. Of course, you cannot expect it recognizes you start swimming if you swim on surface. And recording surface swimming, triggered manually, with no depth data would make only little sense in very most cases, so I am not surprised Suunto did not implement such function.
But if you swim near the bottom, which is rather usual at dynamics, then the depth sensor triggers the recording rather reliably and automatically. Why exactly can't you use the automated mode? Is your swimmin pool less than a meter deep? At Mosquito, the depth sensor fires up the free mode at the depth of 0.45m, which is quite sufficient for almost all dynamic swims.
