Hi Scubaspider, I don't like or use 'octo' regs. Had one once but my LDS was nice enough to give me store credit towords the 2nd ATX100 secondary for it. I just don't like the idea of failing over to a lower standard / harder breathing reg right when I'm most likly to be breathing hard...

There was a videographer working at Dive-Tech in the Caymans last time I was there. He did a full digital film of a 2 tank trip to the North wall. We dove "Hole In De Wall' and 'Lemon Reef' that afternoon. My buddy bought the DVD the next day at the shop. Total run time of our trip...

Using a pony strapped to the side of an 80 makes for crooked swimming tracks... I finaly just rigged it as a stage and carry it that way. So far, I've never needed to switch to it and I 'plan' to never have to, but on deeper (70-130 fsw non-doubles) dives I carry it anyway cause there's...

Here's how I force rounding up or down. The results of this formula list a PPo2 for a given Depth in fsw at a given Fo2 in this format: #.## I force the answer to round up to the next hundredth for conservatism: TRUNC((((Depth/33)+1)*(Fo2/100))*100+0.999999)/100 Basicaly just run the...

OK, My brain WAS seeing things backwords at 5 this morning... The MOD listings are correct. One thing though, the MOD appears to be rounding the results up. EG: for depth 250, 16% o2, I get a MOD of 256 for PPo2 of 1.4 in the Mixer screen. The math works out to 255.75 Based on...

Here's the pic of the shelf unit: http://members.aol.com:/dc4bs/stuff/tankshelf.jpg

Hi Blacknet, I'll grab the new version when I get home from work after 11 tonight and check it out. If I remember correctly from this morning, having the max depth at 80 and o2 at 16% is where the 'hypoxic' depth gave the odd reading. If I set o2 to 17 it was 0 as it should be and if I...

For anyone interested in storing lots of tanks easily at home (or work)... Home Depot sells a plastic '1000 lb' rack that holds 12 al80 tanks VERY nicely. Currently, my budy and I keep 2 sets of double 80s on the bottom shelf, 4 80s and 2 ponys on the 2nd shelf, 2 80s and 4 40s on the 3rd...

Hmm... 1. Check the MOD entries under 'Logistics' It looks like the 1.6 and 1.4 lables should swap positions. 2. Make the calculated fields font darker. Dark grey on light grey is prety hard to read. 3. Something looks odd with the tri-mix Hypoxic fsw calculated field when you set the...

I do very similar to Genesis... uncap the tank valve and reg at the same time. Screw the male and female caps together and put them in the end pocket of the dive bag till I need em again to reverse the process... Makes it much easier to keep track of 4 sets of the things on tek dives if...

My depest air dive was about 206-208 fsw (depending on which guage you want to believe). I looked at those guages a lot that dive because even though I had just checked a few seconds before, I couldn't remember what I had read on them... I'm comfortable down to 150 on air in warm, clear...

Denis is awesome! As have been the rest of the staff every time I've been to CC. My buddies and I were the first ever guests at Cobalt... We were booked at another place for new years 2001 and they went out of business... They DID give us our deposit back but we had nowhere to stay as...

My usual budy is an instructor and, prety much, if you are a friend of his, you WILL be certified... I watched him work with one person for almost two years of pool sessions because they really wanted to dive but had major issues with taking the mask off underwater. So far, I think he's...

I had head that the composit fiber tanks had some issues with delamination when they were used for scuba. They were OK for SCBA because even though they do get wet from firehose spray, etc., they don't get submerged under pressure and have water forced in between the fibers. Am I...

Um... Splunge for me too!

You might also look into Sea dwellers in Hillsdale, NJ if you are that far North. http://www.seadwellersnj.com/ I did my deco/trimix1/trimix2 and just need to schedule time in the shop to complete advanced gas blender with them. I don't know how they are on the earlier classes as I did...

Untill I started wearing a t-shirt under the undergarment, I used to be bothered by the undergarment zipper being pressed against my chest. Only really an issue on longer dives.

My usual buddy and I each carry 2 bags and 2 reels. Since all 4 bags are the 6 foot 50 Lb 'sausages' they are used both for drift hangs and large surface markers interchangeably depending on situation. We each carry a wreck reel clipped off on the right side bottom D-ring and a small backup...

My buddy and I each carry 2 big, bright orange markers and 2 reels... We mount the marker tubes rolled up on the bottom of the BCs in the back with surgical tubing loops. This way one is always reachable by either hand. They are completely out of the way but easily reachable when needed...

Yikes. I feel lazy now for just marking my line with ink. I can see the value of the extra work though as my ink marks are fading out over time.
