Silica Gel for underwater housings
Silica Gel sachets - for underwater housings
These 1g or 2g packs (choose from the drop-down menu below) are individually sealed so they do not pick up any moisture while they are not in use. 5 packs per packet.
Use them often and replace them every few dives. A must have for any underwater photographer, videographer - and great to keep your electronics dry when not in use.
