Marine
A wireless sensor changes the installation path. It does not remove the need to verify the entire data chain.
Start at the display, then work upwards
Write down which displays and autopilot will use the wind information. Photograph their model labels and any network interfaces. Ask the installer to trace the proposed path from masthead sensor to each device. A sensor can be perfectly functional while speaking a different language from the display you intend to retain.
The Raymarine T120 is a useful concrete example: its wireless connection is associated with Micronet. Do not read “wireless” as a promise that any marine display can receive it directly.
Compare access work separately from electronics
Request two itemised scopes using the same intended functions. One might retain a serviceable mast cable; another might replace the masthead unit and include a suitable gateway. Ask who assesses the old cable and how an unsuccessful reuse attempt would change the price.
Include access to the masthead, routing below deck and making good disturbed fittings. Wireless equipment still needs mounting and maintenance access. An apparently inexpensive sensor can become a different project once those jobs are included.
Ask what happens to calibration
Ask which measurements and calibration tasks form part of the handover, and which require time afloat. The answer should refer to the selected equipment manuals rather than a generic promise to switch the system on. Retained speed and heading inputs may also be relevant to the wind information you expect.
A useful demonstration follows the information through the actual boat: sensor, interface and each selected display. Record unresolved dependencies before accepting that the upgrade delivers the functions in your brief.
Choose a supportable installation
Consider how the sensor can be inspected or replaced later. Keep the exact model, gateway details and settings with the boat records. Ask the supplier about current spare-part and service arrangements for the proposed system, including retained equipment.
For an illustrative refit, an owner with an accessible, proven cable may prefer a wired proposal. Another owner already using compatible wireless instruments may prefer a matching sensor. Neither choice follows from mast height alone; the documented installation and future access determine the useful comparison.

Buying questions, answered
Will a wireless sensor talk directly to my plotter?
Only if the exact equipment and connection path support it. Ask for the required receiver or gateway to be identified.
Does wireless mean maintenance-free?
No. Mounting, inspection, model-specific care and eventual replacement still need an access plan.
