Acheter Air Flow Tels Sensor Red One Size unisex

Electronics - Instruments.DAVIS INSTRUMENTS Air Flow Tels Sensor.Tels show the air flow across the sails—allowing you to trim sails for maximum performance.Unlock the full potential of your sails and gain a competitive edge on the water with the Davis Instruments Air Flow Tels Sensor kit. These essential sailing instruments, often called tell-tales, provide immediate, at-a-glance visual feedback on the state of the wind as it flows over your sails. By accurately reading this airflow, you can stop guessing and start making precise adjustments to your sail trim, resulting in improved speed, better pointing ability, and a more efficient and balanced helm. Whether you are a competitive racer looking to shave seconds off your time or a cruiser seeking better performance and comfort, these wind sensors are one of the most cost-effective upgrades you can make to your vessel.The principle is simple yet profoundly effective: these lightweight Tels react to the slightest changes in airflow, indicating whether the flow is smooth and attached (laminar) or turbulent and separated (stalled). This direct feedback allows you to fine-tune your sail shape and angle of attack to maintain optimal laminar flow, which is the key to generating maximum lift and power from your sails.Key Benefits:* Optimize Sail Trim for Maximum Power: Instantly identify and correct sail trim issues. If the windward tel is lifting, you are sailing too close to the wind or the sail is over-trimmed. If the leeward tel is fluttering, you have room to point higher or need to trim in. This immediate feedback loop allows for constant optimization.* Improve Upwind and Downwind Performance: Achieve a higher pointing angle when sailing upwind and maintain a more efficient sail shape when sailing downwind. Proper trim reduces drag and increases boat speed across all points of sail.* Instant Visual Feedback: Unlike complex electronic instruments, Air Flow Tels provide simple, unambiguous, and real-time information. They are the purest form of wind sensor, allowing you to see exactly what the wind is doing right on the sail´s surface.* Durable and Reliable Construction: Engineered to withstand the harsh marine environment, these Tels are made from materials that resist UV degradation and saltwater exposure, ensuring they function reliably season after season.Main Features:* Complete kit includes a balanced set of 14 tell-tales.* Color-coded for easy identification: seven red Tels for the port side and seven green Tels for the starboard side.* Crafted from extremely lightweight, high-quality ripstop nylon that responds to even the lightest breezes without sticking to the sail.* Supplied with highly effective, waterproof adhesive discs that ensure a secure bond to any sail material (Dacron, laminate, etc.) without causing damage.* Includes a comprehensive guide for correct placement on both mainsails and jibs/genoas for the most accurate readings.Technical Specifications:* Product Name: DAVIS...
