    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
