tacktick's Micronet solution - Transmitters and transducers send data to the displays by wireless link. The Wind Transmitter and all the displays take their power from a lithium cell charged by built-in solar panel. The absence of wiring makes for:

• ease, speed and low cost of installation
• weight-saving where it counts
• banishment of mast-removal complications
• freedom from cable-chafe by halyards

The display, too, is independent of wiring, so:

• it can be located where you want
• you can change its location at any time
• you can take it below to read it there
• it isn't linked to a hidden rat's nest of cables which you can't get at to service
• it has no water-sensitive cable joints
