Great Emergency Signalling Mirror

[Sarah]

We've all heard stories of divers being lost at sea, the dive boat forgot them, etc.

As part of a small kit of emergency type of kit, here's a rescue signalling mirror that I keep in my BC in it's own plastic ziplock pouch. It has a lanyard on it.



The instructions are shown on the back as below:




Don't forget to attach a brightly colored lanyard maide out of something that floats and is waterproof like polypropylene, althoigh one a little thicker than shown below.


This mirror as well as an awesome set of really good visual instructions can be found here

As a SAR pilot, we did some tests with CDs and DVDs a few years ago and they really make terrible signaling devices. While they appear bright at close range the diffusion and odd colors created by the signal pits limit their effective range and they aren’t nearly as noticeable from the air as a clean real mirror surface.

by any chance did you test a knife?

just like in the movie "open waters" scary.... since it was a true story i tried searching for the pictures that was taken from their u/w cam (that was found inside a shark) but could not find it...

anyway, this is a nice dive/emergency accessory... i want one....

Hello al, I'm back from a long hiatus for work related crap.

Has anyone heard good or bad about the Sea Marshall lost diver alert?
Personal experiences? Please tell. Is it a waste of money or just an insurance policy hopefully never needed?

What is the range of this non-satellite system?

What is the range of this non-satellite system?

According to the web site, it has a pretty significant range. On the diver version (I suspect they are all basically the same) it depends who's looking for you. Boat to diver, 0.5 to 3 nautical miles, depending on how high the antenna is on the boat and the sea conditions. Helicopter flying at 1,000 feet and you get 7 to 15 nautical miles and for aircraft at 10,000 feet it goes to 35 nautical miles. Of course, somebody has to know you're missing and report it to the appropriate agencies to get these boats, helicopters and planes out and looking for you. So it still comes down to crew awareness and head count procedures, but if you're wearing one of these, I'd say there's a pretty good chance you'll be found.

Portable base unit $650, fixed base units from about $3,000 and up. Lost diver beacon, $350 each.
