Subject: Strobe and D. R. light
Date: Wed, 17 Jan 1996 15:27:26 -0500

     The strobe I use is from "ACR" and has "Ft. Lauderdale, FL" on it.
     Two AA batteries are needed to power the strobe on one end or the
     flashlight bulb on the other.  The o-rings on both ends are on the
     case below the threads.  The cap screws on and passes over the o-ring
     to compress a gasket-like flat rubber ring.  I don't think much of the
     compression seal, but the sliding seal on the other o-ring works good
     because you never twist the caps underwater, only when you change
     batteries.

     I don't take it on all dives, but it has never leaked.  I think it
     must have been down to 150 with me.  I think it is rated for 100
     meters.  The magnetic switch that rotates around the light works so-so
     with thick gloves on.   In general, I like it for the price and
     functionality 'cause I always have a small light for trouble shooting
     when I'm diving and a strobe if I get in trouble. If you have some
     older AA batteries from a remote control or something, its good to put
     them in this strobe, 'cause it will use them up flashing slower as the
     battery voltage/current drops. I got my last one at a marine store
     near Crystal River for about $25.

     Negatives:  The strobe tube will fail if the light is dropped/hit hard
     enough.  Also, the plastic caps tend to crack easily when dropped
     making it leak.  For this reason, I don't let anyone other than myself
     use the light on the surface.  I've got enough "damp-proof" Ike lights
     and accident strobes.  I'm thinking of putting some sort of rubber or
     neoprene shock guard over the ends of the strobe.

     The other thing is that having several strobes going off in your face
     is not fun when you're diving in a dark environment where you might
     want your night vision to catch faint outlines or nice silhouettes.
     Marking an anchor line is a good use and turning them on if you get
     separated/lost is a help.

     Dive Rite Light:

     An improvement I saw at TEK that caught my eye over the AUL lights
     were a solid core power cord.  Also, the screw on lid is a welcome
     improvement from the clamps.  The D.R. rep. told me that they found EO
     terminals that they can put on their cord for a cheaper over-all EO
     setup.  The advantages of not getting a cord leak or transmitting
     water between parts of the light is significant in my opinion.  Add a
     cheaper EO functionality, and I think they will sell a significant
     amount of cords if not the entire light!  They also had a better
     connection/strain relief into the battery canister and maybe the light
     head too from what I understood.

     Does anyone know where I could find my own solid core power cord and
     terminals?  They said theirs was coming from Germany...  I have a few
     applications that I'd rather use them than standard wire.  I take it
     that a solid cord is not readily available???  Can anyone help me out?

     Thanks--DD
