Re: How deep on air?
I will add that 50% for spearfishing makes a great deco gas as it gives you
something alittle richer for off gassing and you only have to climb up to 70fsw to use it. O2 for single tank spearfishing is usless and best left on the boat. Do the math and you will see that the 02 cuts just a few minutes of time and is not worth carring. To get my 39.55 gutted AJ for the SPO yesterday I did 3 dives to 180 on 18/25 with a single 40 of 50%, plenty to spare. Ya ya ya I know sounds like alot of diving for 1 fish. YMMV dive safe. Dago.

What rig were you diving for the SPO? Do you spearfish in doubles, or is the bottom time so short that you went with a single and your 50% as bailout? Really curious as to how you guys normally do this. Safe Diving,

Lots of things to consider! I am not ready or willing to incur the cost of trimix classes and fills. I see now why the double 80s are a better bet for deep dives. How about an H valve with two regs on a 120lp? Is that a viable option? As far as calculating and writting down a schedule on a slate: would a dive computer not take care of that? Or should I have a dive plan thought out and memorized and written on a slate before doing these dives. Max depth I'm interested in is 200-220 feet MAX! I have decided take your advice and go with an advanced deco diving course by TDI. Is that a good option? Thanks, Lee PS: I took down that offensive post with a pic of you in it and want to apologize for it. And here's an offer to Louis Rossignol as well. Let's cut the bs man. I'm willing to start fresh if you are. I think we all are way to old for this middle school crap! Last edited by Bulit7; 08-17-2008 at 08:52 PM. |

Don't memorize the schedule, just write down your stops and the time at those depths, and stick with it. Depending on your bottom time, your stops should be minimal. Again, DAGODIVER should have a good idea on the bottom times that you guys encounter while shooting fish. Quote:
Also, remember that the agency really doesn't matter. It's all alphabet soup. If you are happy with the instructor that you chose, you will be happy with the class. Good luck, I think you will really enjoy this aspect of diving. Safe Diving bud,

I will speek for myself, I always dive doubles as I hate to change my gear to singles and the only singles I have are my deco bottles. this weekend i was diving a set of LP85's with 18/25 in them and a single 40 of 50% under my left arm. I did three dives with the same tanks and had plenty off gas left over. I was keeping the BT's to 15 or less and trying to stay as high up in the water as I could. I run tables and have a computer also. Believe it or not diving the same rig is alot easier than changing tanks after every dive. This is how i deal with the tables. YMMV Dago.

I have the least amount of training on this board, I only know what I know. If you want to dive deep in my part of the world, you learn how to swim fast! I'm not challenging you, just stating facts.

I would think that every time you get in the water it is another "training" dive so with that said I would guess you have more "training" then anybody I can think of. I will take experience anyday of the week. Dago.

Re: How deep on air?
OMG, DUDE!!! I friggin love that!! I'm diving Eagle's nest this saturday, and I will wear "DECO FINS" That should get one hell of a response from the other cave divers
I assume the black is on backgas, the blue is on 50% and the red is on 100%? or am I missreading it? Talk soon bud,
