i use a whistle lanyard, available in a sporting goods store for a couple of bucks. the lanyard loop securely hangs around my neck, and the camera stays in my shirt pocket. if need be, you can unsnap the camera from the lanyard to take a foto, but I usually leave it right on the lanyard
I have a WP cell phone I use for fish pics. I have a lanyard made from 50lb braid I attach to my vest, belt loop, button hole, etc. I then feed it threw my cell eyelet and I’m ready to go. Works great for me. Although it’s WP, that won’t do any good if it’s at the bottom of a lake or fast running river.
Look no further!
I have one for my Pentax waterproof camera which I attach to my fishing shirt, vest, slingpack, or my belt loop when out with Grandkids to the zoo, birthdays, etc. I also have their various zingers on my net, slingpack, vest & they are EASILY interchangeable! They are the only zingers I use.
I don’t sell 'em, but I may be their biggest fan…
