does this mirror float?
It doesn't float by itself, but rather comes with a keychain that you can attach to a D-ring on your BCD. So, I guess it does float, in a sense, but only by proxy of your BCD.
no, but i have it attached to my bc with a light cord and usually stowed away in my bc pocket.
I have not tried it, but no
Not a chance. Keep it on a cord.
No. I have it attached to a lanyard that's attached to my BC tucked away in a storage pocket in a zip-lock baggy.
This does not float. The Ultimate Survival StarFlash Signaling Mirror 2" X 3" SKU: ULTSM2 floats.
There are no specs showing the buoyancy of the mirror. But it is made of Lexan Polycarbonate which is a type of plastic. Knowing it is made of a plastic, I can only assume that it would float.
