Anybody heard or tried to mount your compass to the back of your SPG by useinf like 20 year silicone caulking? Any thoughts? Good bad indeferent?:06: I figured w/ it being caulking if I wanted to take it off I would be able to cut it loose and put it back in a console if I wanted to. All I have on my regs is a SPG. I was wearing my compass on one wrist and my computer on my other wrist. I was just wanting to get my compass off my wrist since I do not use it much.
