Since starting the underwater litter picks, picking litter up underwater has started to become a habit. Almost every dive we find something. Found a really nice piece of hardwood and a paddle from a paddle board the other day. still finding plenty of carrier bags as well though.
Not sure why, on nearly every dive, we find golf balls. Must have a bucket full so far.
The attached photo is the collection by me from one dive. The nice piece of wood weighed more in total than our recent total collection weights! It was 17kg's alone, the total for this one collection was 26kg's.
