Haigh and clear water in the same sentence? What happened while I was gone?

"Best" is really subjective in a dive knife. As was said above, if you gave a profile for a typical dive it might be easier to make a suggestion. The old steak knife suggestion has a lot of merits as well. You can get a package of 6 for a few bucks at almost any grocery store. Knives are one...

Doesn't seem like that big of a deal. 3 divers. 5 remaining 2nd stages. The chance of both remaining divers needing to share air is pretty slim.

Everyone here missed the boat. The best part of UPC is watching the new guy try to get the thing under water. You have to descend with a whole, uncut pumpkin. All cuts are made under water.

Here is kind of what I picture happening in real life usage: diver wants to ascend. computer adds air to BC until ascent starts. (delay due to inertia causes overfilling) computer detects a rapid ascent (due to too much air in BC) and vents air. computer vents air until descent starts...

We can add a GPS and an integrated DPV then pre-program the entire dive. All you have to do is strap in and breath. dkktsunami, "super yo-yo of the deep" rofl

"To rise in the water, a diver adds air to the buoyancy control device." Anyone else have a problem with this?

My bad. I did miss the part about being the third dive. I was going on descent to 60' then surfacing at proper speed.

I get the point about checking the boats O2. What I don't get is the dire need to use it in this case. From what was said in the op, DCS was not a concern.

My suggestion would be to not surface with the bag. Locate your target, attach the bag, then inflate just enough to get the item neutral. Swim around a bit with the bag and item to make sure it is truely neutral, then deflate the bag and do it again (maybe with a different object. Take the...

I hadn't looked at the profile. If what is there is correct then the OP is still quite a bit away from meeting the qualifications. I don't even know if this is a NAUI course, which if it isn't the TA won't help anyway. I was just p[ointing out there is a shorter path than DM or AI top be able...

Look up NAUI training assistant. They can do almost anything an AI can do, they just don't count towards student / instructor ratios and have to be supervised.

Smiffy, The thread has been dead for 4 years. The link is likely equally as dead.

If it had a + rating when new, the rated capacity includes the +10%. Scotty D: 1 LDS guy : 0 That sound means we just entered the Lightning round!

What you have, although maybe appropriate for your needs, goes way beyond a first aid kit. The vast majority of people do not need, nor are they qualified to use, a suture kit.

That last thought was what I was getting at. You would have to maintain "excess" air in the bag or all of the buttons would be constantly pressed by the squeeze. As long as there is an air gap around the camera the camera itself is in no danger of crushing.

This is the part I am having trouble with. I hope he isn't an instructor.

Actually, I don't think that is true. My thinking is that would be true and there would be problems if the camera case were a solid, air tight container. Since there are gaps and holes in the case, the pressure is equal from all sides, including inside out. Comments?

If you are just wanting a first aid kit, go out and buy one. They aren't that expensive and come in a nice box.You will probably pay a lot more for the individual pieces to put one together plus the ready made kits come with a manual. If you are determined to build your own, here is a basic...

I have studied that photo very carefully and I am not convinced. If you look closely there are tell tale signs that this is a photoshop job.
