Rig-Sense As every sailor knows, rig set up is key to performance on the race course and being able to repeat favourite rig settings for differing conditions throughout the season is even more important. Until now sailors had to rely on basic tools which often left them frustrated with inconsistency for critical rig measurements. Spinlock Rig-Sense is a new rig tuning tool developed for consistent and repeatable measurement of loads on wire and fibre. Compact, durable, lightweight and easy to handle, Rig-Sense uses a composite leaf spring that is calibrated to output repeatable tensile load readings to a direct linear scale in Kgs, rather than having to check and calculate loads on a complicated set of tables. With Rig-Sense you can quickly and reliably take your readings to compare and adjust if needed against base settings, before heading out on the water. Designed for 2-5mm wire and fibre cable Rig-Sense accurately displays rig loads on a clear, simple and durable etched display, ensuring teams can tune their rig with confidence. Due to its innovative design and use of materials such as stainless steel for the contact points and composite leaf spring, Rig Sense can be taken from boat to boat and loaned to others, confident in being able to share repeatable rig settings.
