First, I would get a stroke free boat arranged. Then, go out up current and mark the wreck, checking the speed of the surface current using GPS or landmarks. Either throw a ball on it, and drop up current by the amount of time that it will take you to get through the 150 foot current layer ( about 2 minutes), take the ball with you by letting it all the way out , arcing a half circle with it upwind and then jumping up current by the same amount, or jump with a freediving float let out on a reel the same way . Boat stays free and divers stay together, with one person designated to secure the ball or float on the wreck, and one person designated to remove it when he sees everyone is ready. Everyone dives the same plan. I realize this will not work for the idiots, but then who cares, we are talking a stroke free boat. Gas is obvious - at least a true 50% helium with a 12-14 oxygen. The wreck is about 250-260, with the profile being more like 240. I would descend at less than 60 fpm, stay down there less than 25 minutes at the bottom, preferably 18-20 minutes. I would use al 80's unless it is cold and calm and you could wear the dry suit and 104's. I would use a 40 al of 50% and a 30 or 40 al of 100% for deco. Coming of the wreck at about 200 on bottom gas, I would do the following: 190-120 - in 6 min 90 - 2 80 - 2 70 - 50% - 4 min 60 - 4 50 -4 40- 4 30 - 5 20 -13 20-10 -6 You can do more 20 foot time if you feel like it, but it is not necessary if you do the lower part correctly. It can also be done in a lot less, but why bother. -----Original Message----- From: fossildiver@mi*.co* [mailto:fossildiver@mi*.co*] Sent: Wednesday, February 27, 2002 7:09 AM To: trey@ne*.co* Cc: techdiver@aquanaut.com Subject: Re: no reply, pls I'm interested in how you look at the whole picture, start to finish.

I will personally pay your fees over there if you are not a member to get you off of here. Otherwise, maybe one of the big mouthed strokes could put up a list for the information-challenged and relieve the rest of us of the burden of their bullshit.

We need to get this clear so people don't walk away with half truths or misconceptions, which is exactly what the morons who disrupted this discussion would like to see happen. > . -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
