Hi Silverman,
just my 2 cents worth.
I virtually only snorkel but I only work still waters, lakes, bays etc. Theres way to much water movement on our surf beaches for snorkelling.
I wear a full wetsuit, as in a separate jacket and long john, mask, snorkel, flippers and weightbelt.
When I say I snorkel I mean I actually work with my face in the water and even though I hardly ever actually swim, I find flippers are essential.
I generally only work depths that I can comfortably run the coil over the bottom without having to dive under to do so. I wear more lead on my weightbelt than is necessary to achieve neutral bouyancy cause once I find a target and dive down to it I can "hold" bottom easily while I scoop, dig or fan the target out.
If theres a life threatening situation, you ditch the belt and virtually nothing will drown you.
The benefits for me by doing it this way are.....
Virtually no one hassles you, you look like heaps of other people swimming around with a mask on.
The suit keeps me warm in winter, protects me from sun and wind in summer, no need for sunscreen.
Jellyfish are no problem, unless you get one across the lips.
Being able to see in the water is a big bonus. When those itty bittys keep falling through your scoop, I eyeball them easy.
When working areas with rocks its easy to pick out goodies from places that NO scoop can access, I get heaps this way.
A couple of places I work I might as well leave the scoop in the car, but take it anyway.
I can see the sometimes appalling amount of sharp broken glass just waiting for a kid to stand on, this I always pick up and put in my junk bag, if it gets too heavy I hop out and bin it.
And of course I get to see the good things, fish, rays, squid, occys etc. Plus the occasional old bottle.
And I can still keep a close eye on the sweet young things just in case one needs rescueing...lol.
Lou.
