Kind of a no-mans land. 5 ft (maybe 5.5 ft for you) wraps around the torso well. 7 is long enough to tuck in a belt (and gives more distance after an air share calms down). 6 ft seems too short to tuck but too long not to tuck.
I used a 5 ft hose (6'2", 220 lb at the time) for recreational...
The attributes of a BP/W that appeal to technical divers appeal to recreational divers: consistent fit, D-rings are placed where your particular body wants them, it doesn't ride up around your ears on the surface, crap doesn't dangle and catch on the reef, no issues with buying the wrong size or...
Yes, most backplates can be used with doubles by merely swapping the wing and removing the tank bands. Since plates can be had for cheap, some will have a dedicated doubles plate, just to avoid removing the tank bands. Others use a single tank adapter which holds the bands/tank, but attaches to...
Does the training cover the dangers of CO2 retention when breathing shallow? I think that's more likely for Avelo given the sales pitch of "adjust buoyancy once half-way through the dive".
Shearwater Teric and likely some of the other models have it. As to usefulness, it allows the average over a portion of a dive to be known during the dive or without downloading to a PC. I've used it to calculate bailout SAC on a CCR dive which was discussed around the picnic table post-dive...
I would try to get an inexpensive mask asap because fit is the most important thing. If it doesn't work for your new shape, address it then. Fins also early on, but they hold their value should you need to resize. (The larger size may also be useful if you get into drysuit diving.) A computer is...
... and use a reg that sees 100x the traffic, who knows how many vomit episodes, and rely on the commercial operator to service before needed (rather than after a customer reports an issue). Ask any reg technician what most rental regs look like when they finally get to them! It's certainly a...
Don't know if that feature exists on that computer, but you can get it after the dive if you write down (or remember) the starting & ending averages and times. Call those T1 and T2, then:
Avg12 = (Avg2*T2 - Avg1*T1) / (T2-T1)
Another option is to import the profile into Subsurface. It can give...
The wing compensates for gas weight and suit compression. 80 cuft + 19 cuft of air weighs 8 lbs. A 3 mm wetsuit will lose less than 4 lbs below the safety stop. The total of 12 lbs is easily handled by just about any wing you can possibly buy.
The main question seems to be whether you want this...
