Well I know it can be a bit of a pain but why don't you tether it on some para cord, One thing to note is that most Items for the Military are drop testing and rated for a meter to 2 and then 3 meters depending on the Item, So I would look it up,No offense taken.
I have a PLRF15C and it's amazing. I don't like to think about what happens if it goes tits up. When I bought it (used), I justified the cost by telling myself it should last at least a decade. Now I'm afraid to take it out for fear it gets dropped.
I found a few specs on LRFs that the Military use from the Bushnells right up to the Vectronix, I will have a look and see if I can find them,
hope that helps,
John.
