I have had wreck diving training from Atlantic Wreck Divers and feel for the limited amount of penetration I do I will be fine. I am also taking some more advanced classes this summer.

By the way, so far the wrecks (other than quarry wrecks) I have entered I kept my hand on the entry way or 1/2 of my body out of the wreck. I am just sticking my head in for a look. After the advanced wreck class and a few others things MAY change.

In the quarries, I go in the wrecks all of the time, but then again I have been diving there so many times, I could find my way around in the dark. Plus they have BIG openings cut all over so there is always a close and easy exit.

I agree with you 100% the quarries are excellent places to practice skills and new equipment and that is why I am there at least 2-3 days / week during the spring/summer/fall.
