Zinc changing time? Not sure? In a new slip or new at this (like us)? Well, don't fear - rig a waterproof camera and a light to a pole and start filming!
On our first attempt it was getting dark (at 4:30!) so I used my waterproof paddling light to help out. It turned out to be too dark on that go so I waited for the weekend and some daylight (I still used the light during the day and it helped).
Secure the camera with some duck tape and grippy camera tripod thingy (we used two, one is probably fine).
Attach a little rope just in case and down you go. Try to stay as still as possible, but c'mon give yourself a break - your camera is duck taped to an oar! Check our one of our videos below, sorry for the shakes. Dive! Dive!
