OrcaTorch SD01 Pro Dive Beacon luce di segnale 2-in-1 costante acceso/flash 1,5Hz

We ordered the SD01 PRO Tank Marker lights to provide visibility and identification of our dive buddies on crowded night dives. The run time on these with a single alkaline AAA battery is phenomenal. I have left one on overnight and it was still flashing 24 hours later. I believe the actual run time is significantly longer. Use of dual o-rings will prevent flooding of the marker far better than other tank marker lights. I highly recommend these for divers.

I bought four of these for a family trip. Blue(x2), Green and Orange. The blue and the green are a rich nice color. The orange on the other hand is very faint and hard to see. These lights have a soft, mellow blink, rather than a flash or strobe. When night diving with these, they do not frighten the aquatic life. These lights are negatively buoyant, and tend to hang down around the regulator rather than float upward. They are made out of an aluminum housing. That is very solid and very durable. It’s a simple twist on twist off design makes it easy to operate without accidentally turning it off during a dive.

It's a nice solid construction and feels like another reliable product from Orcatorch. The LED is suprisingly bright and I like the 5 hr run time I do wish it took a rechargeable battery vs a single use battery and the lanyard hole was bigger to fix bungee cord.
Overall price,build quality,run time and size I would give it a solid 5/5.
