Who the hell needs a WEIGHT BELT with steel tanks on their back in south FL with a two piece wet suit. If they need to add a weight belt then what they really need is an exercise program. With just my steel 95's I sink like a rock and I wear a two piece wet suit (3mm) as well as a hood and vest (also 3mm). -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
