I wanted a hands free light to use for diving when I need both hands free to gather items from the sea floor such as megaladon teeth. I also like to do cavern diving and it would allow me to film. These photos are from a quarry dive and the lights allowed me to explore the dark insides of several boat wrecks. The unit mounted well and I purchased 14500 batteries to obtain maximum output.

The media could not be loaded. I really like the size of this light the most. For carrying multiple lights on the trip, this one seems like it will have some versatility, because it will be easy to tuck in a pocket. I was surprised how bright and focused the beam was for such a small light. Obviously the simplicity of a single AA battery will make it easy for travel. I can also see this being handy to have on my boat. The twist on and off is a commitment for diving, so I can see that I might only carry this for night and wreck, when I want to have the light on the whole dive. But for the price, I'm glad to have this one in my kit.

I have been using this light for a little more than a month with the AA battery in it. I have found it to be very useful as a backup light that fits very conveniently in either my drysuit pockets or in my tech shorts. I find the light beam to be adequate (again with the one AA battery in it) and it is nice that I can always have another light source without taking up too much room. I would like to (and will) see what the light brightness is with the 14600 battery in it. I would like to see how well that works in using it with the mask strap adapter as I am often doing low vis fossil diving for which this would be very useful.

Once I give this a try, I will update my review!!

I was not sure how effective this small flashlight would be but any fears I had were quickly forgotten as soon as I turned it on. Marketed as a headlight, it comes with a mount that can be attached to a dive mask. I'm not a fan of attaching things to my mask because a level of control is lost in where the light shines. Instead, the light was attached to my BCD via a small retractor. The light was so small that it was hardly noticeable.

Capable of using either a standard AA battery or a 3.7v 14500 rechargeable battery, the light is extremely versitle. I used the 14500 battery, which made the small light the equivalent of a primary dive light. The twist on/off removed any worries about inadvertently turning the light off/on. The light is also a great video light for a GoPro or compact camera.

I received this light about a month ago. In all honesty, I was provided it by the mfg to review with the understanding that unlike scuba magazine reviews that are nothing but regurgitated ad copy, I would be completely honest.
The Orcatorch D560 is a small light designed to be mounted on a mask strap with the included clip. It lists two lumen settings depending on the battery used. Either a standard AA or the more expensive SAFT AA.
With a standard AA it is pretty bright. I don't have any scientific way to check the lumens but for it's intent as a back up mask light it is more than sufficient. With the SAFT battery this thing is nearly bright enough to be used as a primary.
However in my area the SAFT batteries are $11 each.
Standard AA is kind of a misnomer because a AA Energizer is not the same as a Eneloop AA or generic AA. There are noticeable differences in brightness. The Eneloop is better than the energizer but not as bright as the SAFT.
The beam angle is acceptable for signaling and has a nice hot spot as well as an acceptable amount of spillover.
The light itself is very nice and the size is good for a mask strap light or with the appropriate mods to it, mounted on a helmet for cave and wreck diving. The only somewhat negative feature is the mount and it's not that bad and is easily fixed.
The mount slips over the mask strap as seen in the photo. At first it was secure in the pool and on a couple of quarry dives. It was on some cooler water wreck dives from a boat where I had an issue. I had already added a piece of cave line from the light to the mask just because I was unsure of the ability of the o ring clip to hold the light. That actually worked fine for a while. The problem came when diving from the boat on a hot day and the plastic clip seemed to soften up and a giant stride into the water dislodged the entire light clip. The height of the drop was roughly 3 feet plus it being on my head subjected it to an impact from say 8 feet into the water. Had I not added that line the light would be at the bottom of the St Lawrence river.
Looking at the clip, I realized the issue and solved it by adding two zip ties as seen in the photo. A small redesign of the clip to include the zip ties would allow this to be placed securely on any mask strap and not be lost. The next issue occurred a week later on a different set of dives when the provided o ring broke. It appears the o ring is of something like 70 duro and those are not that robust. I replaced it with a stiffer 90 duro one.
The good thing about the clip is that unlike other ones that simply hold the light in one position, this one rotates and actually clicks into several positions so it's not flopping around. Highly beneficial when needing to look at your teammate and you don't have to turn it off to avoid blinding them. It's also nice to be able to point it down to illuminate below you when doing something like a search. Less movement of the primary is required.
I do like this light. The clip issues are easily solved and I understand that redesigning the clip and making new molds would not likely be economically sensible so the simple DIY fixes are acceptable to me. Acceptable enough that I am actually highly likely to buy another for my wreck helmet.
