Electronic devices are fragile and valuable. We recommend doubling up their protection by putting phones in waterproof pouches inside dry bags. Cameras can be put in a small dry bag (5L or 10L) placed inside a large dry bag (30L, 40L, 60L).
Ensure your bags are correctly closed and regularly check water resistance before your sessions using a paper towel.
DO NOT SWIM WITH THE BAG OR IMMERSE THE BAG IN WATER.
