Rig-Sense is a new rig tension device for measuring the loads in wire or rope on dinghies and small keelboats. Rig-Sense is simple to use, measuring the tension directly in kilogrammes. Rig-Sense also benefits from being able to be operated one handed, supporting itself on the rig whilst being used. Quality parts ensure long term performance, consistent and accurate readings over time.
