HI ever since i lost a large bass on a stringer many years ago those sharp gill covers etc - I had one made kinda custom made at a yacht dealer using fairly heavy gage sprung stainless steel cable - which is also has a simple but clever fast way to string my fish - will have to post picture not sure how to do that but will have go soon - this stringer consists of a stainless steel barbecue skewer twisted in such a way onto a stainless eye to length of sprung heavy gage yachting cable - then fish tank plastic sleeving slipped over cable cut to right length then slide on plastic empty fishing line spool which acts as fish stop then stainless steel shackle which after made up you can string your fish through gill cover and mouth fish slide down to fish stop then simply clip shackle through eye at base of skewerSo you have a professional stringer! That's the best type indeed. Mine was just a piece of chord with a stainless steel nail. I bought it seven years ago in Sicily and was ok with it. Now I think I'll buy a full metal circular nail like yours.
I must say apart of that that I don't like to keep the stringer to the float cause I don't keep the float attached to my belt and I should swim back and forth to the float to attach the fish: I leave the float....afloat using a weight on the float line to keep it on position, while I swim and dive within a range of 50 meters from it.
