Hiya
I've also got a Omer Moonlight torch. Laying in a corner some-where gathering dust though!!!
Nothing wrong with it, its just that i couldn't get used to diving with a torch. The torch is attached to my wrist by a lanyard. When decending and when i equalise, the torch would dangle in front of my face. Very annoying. Then when i switched it on, the slight "click" it made, would frighten those wary reef fish. But the biggest drawback, for me, was when spearfishing in crayfish season. Then i dive with gun in one hand and the other hand free, just in case i see a cray in its crevice. Grabbed at a couple, only to have the torch jam at the entrance of the crack/crevice/hole!! VERY FRUSTRATING!!!
I've stopped using a torch and have learnt a couple of tecniques that help when hunting in crevices/caves/holes. Close your one eye when approaching a cave. When you look into the cave, then open the eye. Helps your eyes adjust to the darkness quicker. Also try turning yourself up-side-down, so that you can see if there's any fish hiding in the roof of the cave!!! (i've taken a couple of fish that my buddy didn't see, like this!!!


)
The other downside to a torch, is seeing a fish VERY dep in a cave or in a very awkward spot, and being unable to get your gun in to shoot it!!!! :vangry :vangry
Regarding the Omer Moonlight, it did work very well. definitely get the rechargable batteries and ALWAYS try to remove your batteries from your torch after a dive. (torch's seem to switch themselves on when you forget them in your dive bag!!) Wash in fresh water after each dive. I used mine for about three months, but didn't remove the batteries. When i wanted to take the head of the torch off, it was "corroded" solid. Had to use a bench vice to get it lose. Since then it was easy to open!! (lesson learnt - wash ALL your gear in fresh water after a dive!!!)
