Detailed description

Designed for precise and immediate measurement of rigging tension load, the CYCLOPS Smarttune² 5/16" sensor is a wireless solution that replaces existing turnbuckles. It provides real-time load data, essential for optimizing sail shape and sailing performance in all conditions. The Smarttune² also includes a fatigue life monitoring function and load cycle recording, estimating cumulative fatigue and the operational lifespan of the rigging.

Measurement and connectivity

The Smarttune² 5/16" provides real-time load measurement with an accuracy of ±1% of its maximum working load (MWL) of 1.0 tonne, within a temperature range of 0 to 40°C. Its sampling rate is 1Hz, with custom options available. Wireless connectivity is via the CYCLOPS smartphone app (iOS and Android) or, optionally, via a Smartfittings Gateway box for integration with marine electronics systems via NMEA 2000. This version is specifically adapted for 5/16" (7.9 mm) wires.

Installation and design

Installation of the CYCLOPS Smarttune² 5/16" is done by simply replacing the existing turnbuckle, without requiring complex rigging modifications. The sensor body is made of 316L stainless steel with brass threaded inserts, and its housing is Acetal, IP68 certified for resistance to marine environments. With dimensions of 112 x 55 x 18 mm and a weight of 180g, it includes a CR2032 battery offering 2000 hours of autonomy, to be replaced according to instructions to maintain waterproofing. The sensor is designed to operate under tension only to ensure measurement reliability.

Expert opinion

« Expert analysis: CYCLOPS Smarttune² 5/16" for rig tuning »

The CYCLOPS Smarttune² 5/16" ridoir load cell represents a significant advancement for recreational sailors and racers looking to fine-tune rigging performance. Its clear value proposition: providing precise, real-time data on rigging tension, which was previously difficult to obtain without complex and expensive equipment. It is particularly well-suited to lightweight sailboats, sport keelboats, and high-performance dinghies where fine tension adjustments directly impact sail shape and speed.

This sensor is designed for retrofit installations. While rigging work is required (downgauging, securing shrouds), replacing an existing ridoir with the Smarttune² is straightforward and does not demand specialized skills beyond basic sailboat maintenance. The Bluetooth connection to the mobile app is intuitive and provides immediate access to data. For deeper integration into a navigation system, adding an NMEA2000 Gateway box is the recommended approach, enabling centralized data display on helm displays.

The Smarttune²’s robustness, featuring a 316L stainless steel body and IP68 acetal housing, makes it a reliable choice for marine environments. However, it is critical to follow CR2032 battery replacement procedures, particularly maintaining seal integrity, to ensure long-term waterproofing. Its design is optimized for tension measurement; any lateral load or compression on the plastic body can degrade measurement accuracy—a consideration when furling sails or protecting rigging.

Frequently Asked Questions

Need help? Contact us

What is the purpose of the CYCLOPS Smarttune² 5/16" load sensor?

The CYCLOPS Smarttune² 5/16" sensor is designed to accurately measure in real time the tension load on your rigging. It allows you to optimize sail shape and sailing performance in all conditions. It also includes a fatigue life monitoring function and load cycle recording, estimating cumulative fatigue and the operational lifespan of the rigging.

What is the maximum workload of the Smarttune² 5/16"?

The maximum working load (MWL) of the CYCLOPS Smarttune² 5/16" sensor is 1.0 tonne. It is critical not to exceed this load, as an overload at 150% of the calibrated load could cause permanent damage to the sensor and require recalibration.

How to install the Smarttune² 5/16" sensor on my boat?

Installing the CYCLOPS Smarttune² 5/16" is designed to be straightforward and replaces your existing turnbuckle directly. Here are the main steps:

Fully release the backstay and mainsheet. Secure the forestay to a solid point using a halyard or line. Unscrew the existing turnbuckle using wrenches. Apply anti-corrosion paste to the Smarttune² threads. Screw the Smarttune² onto the forestay stud, then onto the chainplate stud, ensuring it is oriented correctly (model/series numbers facing up). Tighten until reaching the reference measurement of the stay taken before disassembly. Remove temporary securing lines and readjust your rigging. No complex rigging modifications are required.

What are the connectivity options for the Smarttune² 5/16"?

The Smarttune² 5/16" sensor offers multiple connectivity options:

CYCLOPS Smartphone App: You can wirelessly connect the sensor to the CYCLOPS app available on iOS and Android to view load data in real time. Smartfittings Gateway Box (optional): For integration with marine electronics systems, you can use an optional Smartfittings Gateway box that provides NMEA2000 connectivity.

What is the accuracy of the load measurements for the Smarttune² 5/16"?

The Smarttune² 5/16" sensor provides real-time load measurement with an accuracy of ±1% of its maximum working load (MWL). This accuracy is guaranteed within a temperature range of 0 to 40°C.

Is Smarttune² compatible with all rigging line diameters?

No, this specific version of the CYCLOPS Smarttune² is designed for 5/16" (7.9 mm) rigging wire. The sensor is designed to operate under tension only, with load applied via the threaded studs in the turnbuckle.

What precautions should be taken when replacing the battery to avoid damaging the sensor?

To avoid damaging your Smarttune² 5/16" and compromising its operation, it is critical to take the following precautions when replacing the battery:

Replace the battery in a dry, enclosed area, preferably below deck. Ensure the battery cover gasket is properly seated. A failure in sealing will allow water ingress and cause permanent damage. Replace the CR2032 battery with an equivalent. Do not use non-standard or other sizes, as this may cause damage. Do not unscrew or remove any fasteners other than those required for battery replacement, as this could damage the sensor.

How to know when it is time to replace the Smarttune² 5/16" battery?

The Smarttune² 5/16" sensor will indicate that the batteries need replacing by displaying a charge of 0.00, even when under load. This means it is time to replace the CR2032 battery.
