bumping an old thread .... Amazon have Campark 4K waterproof camera for £24 atm, amazing value for what what you get, probably because there is a new version out for twice the price. Reviews on amazon and elsewhere seem v good. https://www.amazon.co.uk/gp/product/B01J51W5QG/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
