I have used this torch whist diving some wrecks on the south coast of England and haven't used a bitter one yet.
This torch is on sale in the shops for about £70 although some online deals take it down to about £60. This might seem expensive but for build quality and usability definitely worth every one of those hard earned pennies.
The manufacturer says that the torch is rated to 250 lumens. Quite what this means I am not sure. From experience it gives a good light source in murky water. Diving on wrecks it is great for peering inside and lights up interior spaces well.
When visibility is 3m or below, the torch means you can find diving buddies as the light is well directed into a beam rather than dispersing using a very well designed reflector. (Follow the beam and you find your buddy).
This light beam is about 10 degrees wide and a fainter surrounding ring or 'halo' is much wider meaning that you don't get too startled when a huge fish comes from the side of your vision.
The build quality of this torch is excellent. The metal (anodised aluminium) feels strong and the torch seems well put together when removing the battery compartment and screwing the head to turn it on. The rubber grip on the head for twisting is well attached.
The torch is fairly small compared to other dive torches. It's about 25cm long and fits into one hand easily.
The torch is activated by screwing the head end down to make contact with the batteries. I haven't had a problem doing this underwater wearing thick gloves in cold water. The rubber grip helps immensely with turning the torch on when your dexterity is limited.
When not in use, the small size of the torch means it can be placed in a pocket on your BCD (Buoyancy control device) and doesn't get in the way hanging off with all the other things most divers attach to themselves!
Battery life using 3 x AA batteries is about 18 hours according to the manufacturer. I've used it on about 20 dives so far and haven't had to replace the batteries and it has shown no signs of a weakening light output.
The torch is rated to 120 metres depth. This is well above what any but commercial technical divers diving on complicated gas mixes are going to be diving too (I believe 50m is the maximum diving with air before oxygen toxicity comes into play)
The only issue I have with the torch is that the little karabiner supplied with a cord for attaching to your dive equipment is extremely weak. I have replaced this with something stronger as I don't really want to drop a £70 torch in the sea never to be found again.
Overall the best scuba torch I have used. Beats a lot of much more expensive torches for ease of use, build quality, light direction, battery life and more. I can't recommend this highly enough.
