just get in water, find the weed, anything from 1m to as deep as you want to dive, look for holes/cracks that look big enough to put your arm in
and start looking
when you find one take note of the position that the sea would come in, 9 times out of 10 all the others will be facing that way so you can narrow your search
find 99% of mine in less than 5m
