--=====================_23632029==_.ALT Content-Type: text/plain; charset="us-ascii"; format=flowed WE are on the same page.........drifting back and scootering up is the dumbest thing I've ever heard. I was wondering how long it would take someone to figure that out. Every good diver who is diving on a fixed line knows you go against the current and then takes the easy ride back to the line WITH the current......... he is the first fool to do that shit, has his first scooter.......... Take note, when diving a wreck from a fixed point and there is current present start your dive into the current if you can. That will allow you to judge what it will take to get back. Do not go with the current because it is so easy, before long you could be to far and then realize it takes too much effort for the long swim back to the fixed point. If he was going to dick around with the scooter, do it into the current and then if it fails he will drift right back by the line. Read the report again..........its all there, everything you need to see what he is coving up.
