@inquisitAhh I see... it's literally an on the surface buoyancy is roughly not too buoyant at the end of the dive. The removing the corresponding weight to simulate an empty tank makes a lot of sense, I've wasn't aware of that detail. As your wetsuit thickens or the most shallow depth gets...

yes, it seems likes it connected via 2x zip ties. But its not on a standard elbow and since I read it was sewn in... it scares me a little to cut the zip ties off. Maybe I should just man up and do it

I seen some stuff on the internet that the corrugated hose is sewn into the BCD? Is there a way to DIY replace it or do I have to send it back to poland? I just need to extend it a couple inches. Thanks

True a minute isn't necessary, I just choose an arbitrary but sufficient amount of time. Just enough to dump all your air, make sure you are breathing normally. I guess 5-10 seconds could be sufficient. But 20 seconds would be more then sufficient too.

I never really understood the on the surface weight check. I skip all that and go right to the actual check. 1) Wearing all the gear you want to do the check with (lights, specific tank, specific exposure). I would put a 2lb lead weight on your tank cam band and another 2 lb lead weight on your...

@wetb4igetinthewater I think the standard new ow diver is poorly trained via padi. My cousins had been recently cert. I spent the first 2 dives dropping their weight, redoing weight check, teaching getting neutral, even teaching them to get in a certain position to dump air effectively. I...

Luckily his body was recovered. I wish the best for his family.

Does this mean the 1st free service is still available for use? You didn't like them for sidemount?

I'll expand on why ppl add 1 or two lbs. Typically new divers arent very good at completely emptying their bcd. They dont know what position to be in and for how long. The second reason for adding an extra lb or two is because they cant control bouyancy via 20% lung capacity. So when they...

I read your post again. If you are going to be doing a shallow dive and have uncontrollable ascent issues, you can add a couple pounds as training wheels for 5-10 dives. After that I would insist you always keep yourself properly weighted. If you are diving deep, do not add even 1 lb.

I was dealing with newer divers earlier and the issue is really an event that causes your breathing to bring you up. 1) get neutral and hover above the floor for 5 seconds. 2) be aware of depth changes. If you go from 100 to 90 ft, not much change in your bouyancy but if your in the shallows...

taking it in. It was an XL mens used and we got a used one for my gf. Shes going to covert it to her size women's small/medium. She gets cold easy and a new set of undergarments would be too pricey atm. Tys the reply, we got it this week and it looks it wont be too hard to do.

What would you guess the thickness is vs a wet glove. 3mm?

I use the dgx ceramic so no issues.

... that would of saved me a lot of time... Another advantage of subsurface, it a line per tank showing gas pressure over time. The line is also colored from green to red for relatively low to high consumption based on the dive. Super cool to see what situations causes you to much higher than...

@RayfromTX That's a good point. I use subsurface as my log and basically do the same thing for a multi tank dive. I never checked if it recalculates sac, but I just looked right now and it does! It'll do it as soon as I add the extra tank sizes with corresponding pressures. @GLightcap I'd just...

Ahh ok, I misunderstood what you wanted. You need average depth of dive Start and end pressure for each tank Tank size And total dive time Let's say 2x11L at 200 bar. Ending pressure 50 bar and 80 bar. 30 minute dive. 30m average depth. Air volume breathe at depth = [(200 bar - 50 bar)*11L +...

Per my number #3, read it again. I'll also try to clarify, I'm saying per how shearwater calculates sac, it only calculates for a specific interval. If you are breathing from the tank with a transmitter for more than that internal it will be accurate. For ex. You have 2 tanks at 12L. You...

*note: I believe it disregards your first 30 or 60 seconds in the dive for the sac calculation

Why do you care about at the moment sac rate? Here's some options 1) Easiest thing to do is drop to depth and swim at constant depth for 20 mins. You can write your starting and ending pressures and get your typical sac. If you want to be lazy just breathe the tank with the transmitter. 2)...
