Hollis SMS100 Sidemount BCD Purchased from a diving shop in Yokohama. It's still in good condition. I'm selling it because the size was a bit too large for me. I've set it up for sidemount diving, following online tutorials, but it can of course be returned to a single tank setup. Please understand that this is a used item before purchasing. Operation and appearance are based on the confirmation at the time of listing. Diving equipment is related to safety, so please be sure to inspect and maintain it yourself before use.
