Trafield Powerful 10000 Lumen Dive Light - Waterproof Scuba Diving Flashlight with LED, High Lumens Underwater Light for Professional Divers | Perfect for Night Diving, Cave Exploration, Fishing & Outdoor Adventures

Been using this strobe/flashlight combo for decades (sport diving/coastal sailboat racing). When the original finally crapoed out after close to 20 years, I got these new ones. Design is great.Strobe is nice and bright, as is the flashlight. It appears water resistant at least to 60'. The old one was fine to depths approaching 110', so I have confidence in this new model.If I had a concern, it would be the magnetic switch to turn the unit on is pretty light, so I've accidentally turned it on once or twice.One option which would be ideal is a red lens cover for flashlight to reduce night blindness.Great product for the moneyGreat productI've only used it once diving, since I just received it last week. It's better than the dive light/strobe that I had before as it is much brighter. Probably because this light uses 3 batteries and my old light used 2.It's small, so I will keep it in my BC pocket for dives where I don't usually need a light but may want to illuminate under a ledge or into a wreck. And the strobe would be for emergencies or to attach to the anchor line, so I can find it if visibility is bad.I've had one of these for more than ten years and it's always worked, never leaked, and is always bright. I just bought another for my buddy.Very disappointed with this product. I opened the package & followed instructions to install batteries. Directions said to unscrew the strobe cover, then remove the strobe part & pull out the battery case. I could not remove the strobe part no matter how I tried. So I unscrewed the tiny screws on the strobe part & still could not get to the battery case. Changing batteries should only take 60 seconds but I fussed with this for 30 minutes. Very annoyingWe had high hopes that this strobe light would work on our dive boat, however it came up short. We used it on our safety stop down line at 15ft to mark the boat location, and while it did flash the entire dive and was bright, it leaked and was full of salt water at the end of the dive.Very cheaply made. Returned it after first use.Faulty product with false advertisementI bought tis to replace an old strobe that has given up. It is more bulky than the old one so would not mount on my BC the same way. I have yet to test it in open water but I think it will be fine. It appears to be identical to the Beaver / Northern Diver models but a fraction of the price.
