I'm selling one of my two Sea and Sea underwater strobes, a 120 Duo. I bought it new back in 1996 and it is in 'like new' condition and looks new. This is because I've used it only a couple times. The on-off, switch's 'detent' ball bearing is not in its place and you can hear it rolling around inside the strobe. This does not affect operation of the strobe. The strobe came this way and I never bothered with sending it in.
I bought the strobe as a backup to my other 120, which while very used, is still working, so never needed it. I am asking $300.
