Let me clarify what i intend to use a pinger for. First of all i never dive from an anchor line because the anchor can get dislodged during the dive. I dive from a shot line, there is no boat anchored to it or anything that might drag it off. A good location for attaching the transmitter is on the shot line just above the wreck. The transmitter is very mall and it fits in a pocket. The situations where a pinger comes to use is primarily when scootering. I do not want to lay reel while scootering if not absolutley necessary. The reason is that it's a pain to reel in while scootering, you have to clip the scooter off to your butt D-ring and swim it back. I would of course not trust my life on an electronic device such as this. I do not trust electronics, that is why i don´t use rebreathers. If missing the accentline means a great increase in risk i use a reel. I don´t think losing the accent line on a 60-70m wreck dive with no current and all the deco gases carried adds a tremendous amount of risk. When wreck diving i very seldom lay reel, most dives i do is in pretty good vis and i never bother to dive junk piles. In good vis on an intact wreck there is no need for laying reel in my opinion, if you have some basic knowledge of how a ship is constructed navigation is easy. So then why bother using a pinger? I would use it to help me out in the very unlikely event that i would still get lost. When diving wrecks that i have never dived before this is more likley.Using á pinger should increase my chances of finding the accent line. Do you agree on that? When leaving the wreck looking for artefacts using a scooter a pinger is also useful. In this case (in any situation really) it is safer to use a reel but the pinger is more convenient. For your conditions a pinger is maybe not a good idea. I don´t know how you plan the decompression and i don´t know how your boat monkeys handle a free drifting diver under a bag. If this particular pinger is good or not i don´t know. I will try to lend a unit and test it out. I will report back to the list. I mentioned that i have used a pinger before. We used pingers on the 1997 Britannic project and they worked fine. I have no idea what brand it was and i did not bother to find out more about them because they where to expensive anyway. if the uwatech unit is good there are some applications where it might be useful.

The logic I have seen behind using these devices was, well you saw the last email. Scootering didnt come to mind. Still im wondering, have you had to float the pinger, and if so how have you handled this?? The wrecks I have dove are mostly junk piles and if we get 10 ft of vis, its cause to have a freaking party, so if there is a reliable brand of pinger out there I would like to know about it, line reels are tedius but a necessary evil when the boat is anchored and the pingers I have seen are, shall we say, less than robust enough to bet your life on. best wishes for your upcoming seminar, Al Marvelli Ingemar Lundgren wrote: > I just new that somebody would jump at the chance at criticising this.
