XTAR SD1 Scuba Dive Strobe Beacon,4-Color-in-1 (White,Red,Blue,Green) 8 Modes Diving Signal Light Night Dive Flashing Marker Light,for 100M Underwater Diving (SD1 Set)

Has done very well on 4 night dives. Bright light. Still on the original battery. No leaks. Well built. The two modes, steady and blinking, as well as the different colors to choose from is a plus.

I’m giving it 5 stars because it’s a great product. I personally used it for training on live fire ranges, it’s excellent to mount on your hat, flak, belt, clothes, etc. my only issue is it’s so bright! But I can’t take away a star for that as it’s a scuba light. But the ability to change colors is perfect because for night ranges, different color lights mean different things, green could be a shooter, red could be instructor, blue could be medic, etc. and it appears very durable.

I have used this light attached to my first stage on night dives and low visibility dives. Works great and is bright on all colors. I like the ability to choose between on and blinking as well as the different color options.

I've used this beacon about 5 times and have been very impressed. Very bright and I love the options for different colors so my wife and I can always keep track of each other on night dives.

1 of 2 lights performed well. The second one failed on the first SCUBA night dive. Seal failed and caused a dangerous reaction with lithium battery. Could not bring damaged light back on airplane due to lithium battery damage and inability to remove corroded battery from light. No way to return damaged light for examination to prevent failures for others or obtain a replacement light. The 1 of 2 that still works has performed well for 15 night dives.

Like the product alot

Seems well made, fast shipping, good features. Took off a couple stars because it comes with an uncommon rechargeable battery but no charger.

It is perfect for night diving and for diving.In remote areas. It's small and convenient and has several different colors. I'm glad I bought it.
