Honed by extensive testing and refinement, the SMS
Katana, designed by Nick Hollis in partnership with leading cave
diving instructors, is a cutting edge cave penetration tool
without equal. the SMS Katana design builds on the proven
SMS100 and SMS75 sidemount systems but was further
streamlined to reduce drag and allow for easier movement in
confined spaces providing optimal performance in the warm
water cenotes and caves of northern Florida and Mexico.
