ORCATORCH SD01PRO Upgraded Bright Dive Signal Light, Submersible Beacon Mini Tank Marker Light with Constant and Flashing Modes, for Scuba Diving and Night Time Visibility (Green)

This is my second scuba marker light. Performed well at 100 feet underwater. Battery lasts the entire dive.

Made keeping track of my buddy while certifying for night diving much easier. I bought two one for each of us and in zero visibility situations or 4-5 feet visibility I could tell my dive buddy from others in the group.

This makes a great tank light for night dives. Recommend using two small zip ties on the yoke so the light is positioned on top and therefore visible from all perspectives.

It looks cool and is functional. It's just not very bright. I was hoping for more. It has held up well during multiple ocean dives.

Great product. Works as intended.

After 60 feet or so the light starts to fade and the blackness begins to envelop you.I wanted a simple and effective way for my buddy to be able to see and track me in these dark conditions. I found the Orcatorch SD01 and thought it was a great concept and wanted to give it a try.So how did the SD01 do?In the case: It comes in a small zippered case with spare o-rings, a single aaa battery, a lanyard, a user manual, and a warranty card.Build and design: It’s built tough. The overall quality feels durable and solid in hand. The threading screws together with ease. It came with lubricated double o-rings that should help keep it watertight at depth.Depth Rated 150m IXP-8Size: 77.5(Length)*19mm(Diameter)Net Weight:23.5gPower: It’s powered by a single AAA battery.Max Runtime: 108 hoursSimple: The light is intuitive and easy to use. Simply twist on and off. From off, a one-quarter turn of the switch will activate the pulse setting.Attachment points: There is a single attachment point on the tail of the light. You can use the provided lanyardFinish: The finish shows little wear after multiple dives.Final Thoughts:Pros:•Bright and sustainable output.•Solid build quality•Good Size. Small enough to travel with. Very lightweight.•Twist On/Off for easy use.•Includes one aaa battery•Long 108-hour runtime allows for multiple dives before needing new batteries.•Adds safety to any dive•150m rated depth makes this usable to technical and recreational divers.•Good valueCon’s:•A rechargeable 14500 battery would be more efficient and add very little size. It would make the battery rechargeable.•Strobe pulse speed is not controllable. It is faster than I would prefer.•Light is one color only. Multiple colors in a single unit would be a nice option.•A non-pulse, always-on glow stick-like option would be a nice feature.

The media could not be loaded. Excellent dive beacon for letting your buddies or the boat crew (and other boats) see your presence in the water. It can alternate between a pulsing green light, or a solid green light.

This is a quality product, but I would like to see the lights be brighter.
