Looking Good !
Have you guys tried mounting on the chest or hip, works best for me ? A GoPro camera chest harness works well, go for a clone as the genuine one a bit pricey !
At times have also mounted mine in a backpack frame, once set up all you need to do is reach round the back to switch on/off.
(working/diving in deeper water shaft mount probably the most suitable)
Enjoy the good weather !
