SF: Traction and compression forces, fishing
SF measures and records tractive forces in a fishing string, buoy moorings or any structure secured by a cable (aquaculture cages…). SF is waterproof down to 300m and shock resistant.
Down to 50 meters, data can be read underwater thanks to a waterproof Data Pencil, without removing the SF.
