So we were having some fun with the GoPro today at the Pier in Port Erin, Isle of Man. Unfortunately, on my last dive, the wrist strap failed and the GoPro dropped to the bottom in about 12 foot of water and got lost in the Sea Weed.
A very helpful (and unknown) scuba diver jumped in and after 10 minutes of searching the seabed, found the GoPro and saved me a hefty £350 bill for a new one.
Thank you very much to whoever you are.
