Tom, buttmounting a light is unsafe. Not as unsafe as not breathing the long hose, or trying to dcompress on useless computers, or using th wrong backup lights,etc. but unsafe none the less. Here are the reasons why (again). They are in no partticular order of significance. 1) Rule Number One violation - ONLY a stroke would butt mount a light, and that is all I should even say about it, but for the new people , I will go on . The strokes can kiss my ass. 2) This causes a trim problem with all but the worst light. 3) This is blocking the proper position to tow from, which requires that the head of the towee be against the tanks of the tower. DO NOT LISTEN TO anyone who does not actually do this, and any convoluted ride-on towing scheme I will rebut with Exley's tales to me of real ,life situations. In fact, Exley said, "George has taken the risk out of scooter diving". We do it, we know it. 4) The second scooter and exploration reel are pulled in this spot, and can be disconnected from the front. 5) The butt light requires a convoluted series of hose clamps and d-rings to attach it to the tanks (metal to metal - a no no), which are entangleing devices, as is the butt light itself . 6) The butt light makes sitting down on a boat or rigging up before a dive a real "pain in the butt", and subjects the light to damage. 7) It is dangerous to have entagling devices behind you that you can not yourself free. 8) The butt mount makes it difficult to reach your on/off switch - an aggregious safety violation. Using a switch in the handle is an unnecessary additional convolution required to compensate for doing it wrong in the first place. The twist handle ranks among the worst engineered, most poorly conceived, uselss pieces of shit I have ever seen. It works only intermittantly, and in salt water, using the handle as the cathode of the ciruit is absolute stupidity at its best. 9) The butt light exposes the switch and cord to unnessesary damage. 10) The butt light requires a ridiculous amount of additonal cord to make it to the hand, and sujects this to snagging, snatching , and fouling, as well as additonal stress and damage, both along the cord and at the two terminal ends. And convoluted cord routing schemes are not the answer. 11) With the large OMS 121 tanks, the butt light becomes the thigh light, and for short people , like Sandra Dirksen, it becomes the knee light. 12) Buttmounting provides a bad excuse for not breathing the long hose, as the hose will float up if it is not run under the light or the knife, which should be on the belt only, when you get into a vertical position. 13) Buttmounting encourages people to put stage bottles on both sides, thus really slowing them down and making it impossible to ride a proper scooter. Keeping the bottles left and riding the scooter with the right hand keep the bottles still, not moving, and out of the prop wash. 14) Buttmounting diplays an attitude of not being a forward thinker, and therefor is like wearing a sign on your back saying, "Dive With Me At Your Own Risk" That is all I have time for now. I will add to this later. -G
