hello all,
I have been diving regularly for about 5 years. I mainly dive to 18m or less to hunt lobsters.
I have just got my first backplate and wing setup. Once I get used to it I am planning to do some more training to work up to dive some wrecks that sit in about 42 m.
I will start with my Padi advanced open water and nitrox as I think I will need to do them before I can do the below.
Some of y'all really seem like you're jumping the gun with recommendations to go straight to tech courses.
It seems to me like he should get some more experience diving deeper than 100' before he takes a course that certifies him to 150'.
I don't think TDI AN/DP or the PADI Tek courses teach you how to use a reel and run a line. The instructor may include bonus material, but that is beside the point. I don't know whether Fundies includes laying line, but I suspect not. I was taught how to shoot a bag and run a line during my (non-penetration) SDI Wreck course. Shooting a bag was part of AN/DP, but laying a guide line was not.
It seems to me like he needs to take a Nitrox course, a Deep course, and a Wreck course (to learn how to run a line, even without penetration), before he moves straight into tech courses. Particularly given his stated goals.
Personally, if I were going to take exactly one tech course ("one" meaning a class that is or can be completed in consecutive days, with no breaks for practice or gaining more experience), I would take (as I said earlier) TDI Intro to Tech/Advanced Nitrox/Deco Procedures/Helitrox, which is commonly offered as one course. That will teach you how to dive doubles and certify you for deco dives with unlimited deco time, to a max of 150' (45m), using 1 deco gas (up to 100% Oxygen), and with up to 20% Helium. I'm not saying there isn't one, but I don't know of any other agency that offers 1 course that gives you all that capability.
