Cyclops Marine Bottlescrews - Load Sensors For Standing Rigging

  • Smarttune

    • smarttune is designed to replace your existing turn screw.
    • Live, static & dynamic load data to your phone via the smartfittings app, or to your on-board instruments via  gateway.
    • Available in 5 sizes, from 5/16″ to 3/4″ (turnscrew size).
    • No need for cables, the device communicates with your phone or instruments via the latest wireless technology.
    • Powered by easy to source batteries.
  • Smartlink

    • smartlink devices are the smallest, lightest, strongestmost versatile load sensors for your boat.
      Easily added in-line of any ‘soft’ stay or sheet, from mainsheets, to code sail tack lines, to backstays and runners.
    • Static & dynamic load data to your phone via the smartfittings app, or to your on-board instruments via  gateway
    • Available in 5 sizes (600kg / 2t / 5t / 10t / 20t)
    • No need for cables, the device communicates with your phone or instruments via the latest wireless technology.
    • Powered by CR2032 battery.


  • Cyclops Marine Gateway

    • Communicates with NKE, NMEA 0183 and NMEA 2000 devices (currently excludes Raymarine).
    • Enables Cyclops devices to display load data on most modern on-board electronics (see below for full compatibility).
    • Up to 50 sensors can be connected, you can view sensors from all over the boat in your on-board displays.
    • Splash and dustproof to IP54 rating, mounted below deck or on the forward bulkhead.
    • Data can be downloaded and exported for use in sailing analytics software.
    • For use on yachts with carbon and conventional hull materials.
    • Connect to the Gateway’s Wi-Fi from your phone to easily set-up.
    • User-friendly interface.

Precision Load Sensing Technology Integrated Into Pins

  • Load Pins

    Load Pins from Cyclops Marine replace existing pins to measure loads applied to standing rigging, such as forestays and shrouds. The pins are supplied factory calibrated, with ‘digital direct’ load output from the pin connector and no external housing to worry about, as the amplifier is incorporated into the pin.

    The result is the most reliable, accurate, robust load sensing solution available. All calibrated parts are encased within the pin which can be detached from its connecting cable making it compact and practical.

    Cyclops load pins are entirely custom designed around customer requirements and our experienced technical team is available to help inform custom specification.

    • All parts manufactured in the UK.
    • Simple installation with standard tools, no need for in-situ recalibration.
    • 17-4/PH Stainless Steel as standard (other materials available).
    • Designed to operate in harshest marine environments.
    • Temperature compensated within -10º to +40ºC range.
    • Rated IP68.
    • Digital output from pin connector reduces complexity of installation and risk of damage.
    • Various types of anti-rotation methods available, including keep plates and tear drop fastener tabs to maintain alignment with load.
    • High accuracy calibration, typically ±1% of MWL.
