Hi Goldfever, yeah I wade with suit, mask, snorkel, flippers to.
Makes such a difference clearly seeing the bottom.
If you want to cover every inch you can scrub the coil along the sand, this leaves a distinct mark. Makes it soooo much easier to grid being able to tell where you've already been.
Breath hold comes with a bit of practice. Can make a huge difference recovering goodies that are down cracks or between rocks. I've recovered some great items that would NEVER be picked up in a scoop.
Lou.
