Clinometer Twin Scale Plastimo — Dual-Reading Heelmeter for Precise Trim

Fine‑tune your boat’s performance with the Plastimo Clinometer Twin Scale, a compact analog heelmeter engineered for quick, reliable angle readings at a glance. Its dual‑reading design combines a fine scale for micro‑trim and a wide scale for larger heel angles, helping you sail faster, safer and more comfortably. Built for marine use and suitable for indoor or outdoor mounting, this instrument delivers clear, high‑contrast graduations and a smooth, damped movement that remains readable in chop. Choose a trusted sailing essential that balances accuracy, durability and easy installation.

Key Benefits and Applications

• Optimize sailing speed and balance — Keep your heel angle in the sweet spot to reduce drag, improve lift and maintain efficient sail shape during cruising and racing.
• Two scales for every condition — Use the fine scale for upwind trimming and training, then switch attention to the wide scale when conditions build and control matters most.
• Instant, glanceable readings — High‑visibility markings and a stable pointer make it easy to read heel angle quickly so you can focus on helming and trim.
• Built for real marine environments — Robust construction resists spray and sun exposure, ideal for cockpits, companionways and nav stations.
• Fast, tidy installation — Slim profile and screw mounting allow clean placement on bulkheads or dashboards without cluttering your helm.
• Great for training and consistency — Give crews a common reference for repeatable trim targets and smoother maneuvers across different wind strengths.
