Hi, Just cracked the very basics of snorkeling, ie breathing! I now have a bouyancy issue. I need to start using fins, but I am too far out of the water to kick normally, let alone with fins. I am investing in a wieght belt with quick release buckle, but am considering ankle wieghts as well. Are they safe or am I wasting my money? Any suggestions or advice welcomed. Thanks, Wendy.
