Comments about Tektite Mark Lite Strobe:

I use this product as a safety strobe or marker. After more thn a dozen dives, it seems to remain waterproof and works fine. I mount it on the shoulder harness of my BC, so the long bulb housing can sometimes get in the way, but so far it hasn't been a problem. Don't forget to take batteries out for extended storage and lube o-rings occasionally.

Great to use on tank or use to make a marker on bottom of floor. beam not brite to mark decent line below if you below 40 ft.

I use this for shore night dives in areas that are hard to navigate at night. A return beacon, if you will
