Not sure, maybe check with Fishing Specialist. I also want to get one, but for now, i keep one of the soft measuring tapes that they use for the clothing industry in a water tight container. It has a kind of plastic film on, so it doesn't damage easy it you put it on a wet fish.If you look in PnP where they keep the sowing stuff, it normally hangs there and at about R5, its a bargain, ha ha.
