Comments about Tektite Mark III LED Strobe:

This is perhaps the worst item I've ever bought since I became a diver. I put the batteries in to try it before a trip, and the bulb completely twisted off as I screwed the top on. I have several twist-activated lights (and prefer them as a tech diver), so I did not screw it on incorrectly. I would never consider buying anything from tektite again. Only Princeton Tec, Halcyon, and Big Blue for me from now on.

The light is bright. I have not had any leaks so far. I have 2, 1 for me and 1 for my son. The only con is the reflector housing is a bit too long. It makes carrying it is more inconvenient. My next light will be more compact.

This strobe is an excellent piece of emergency equipment to own. I carry it in my BC pocket while open water diving in the event of surfacing away from the boat, being left behind, etc. Also use it for night diving, both as a tank marker and for marking my position on the surface for shore support to identify. I have also used it for shore marker. Very bright light, long battery life, but very long and wouldn't fit in most BC pockets.

Comments about Tektite Mark III LED Strobe:

I have always used chemical lights (Cyalume) sticks for night diving applications but they are now outlawed in many places.

This strobe definitely filled that need and worked very well. It was very easy to see where my partner was at all times even at a good distance when the visibility was not optimum.

One minor nit: To turn the light on you have to really crank the head down hard to make contact with batteries. I had to completely disassemble one of the two strobes that I bought and reshape the copper inner parts to get it to make contact.
