52mm Rudder Indicator Gauge (ROD-5)
| Reads | Rudder position (±40° from centre) |
|---|---|
| Resistance | 0–190 ohms |
| Gauge size | 52mm diameter (85mm version available) |
| Power | 12v/24v |
| Waterproof rating | IP67 |
| Sender | Rudder Indicator Sender (ROD-5), sold separately |
| Backlight | Red or yellow |
| Face | black or white |
| Bezel | black or white plastic, or 316 stainless |
A 52 mm analogue rudder-position gauge showing up to 40° either side of centre — a clear, at-a-glance reference when manoeuvring in marinas, narrow channels and busy ports.
It works with the Rudder Indicator Sender (ROD-5) (sold separately), mounted near the rudder post. The ROD-5 system has dual outputs, so one sender can drive two gauges — useful for a second helm station.
It is not backwards compatible with the discontinued ROD-4 sender, so check which sender you have before ordering.
Available in a choice of face and bezel colours with red or yellow backlighting, and also as a larger 85 mm heavy-duty version.

Fitting on 12V or 24V — and why a voltage regulator helps
A 12V system is never a steady 12V: it sags under load, rises to 14V or more on charge, and spikes as things switch on and off. The gauge sees all of it, so readings can wander with the state of the electrics rather than with what you’re measuring. A voltage regulator delivers a clean, steady voltage whatever the supply is doing — so the gauge reads consistently, the backlight stays even, and sensitive electronics are protected from spikes.
On a 24V system a dropping resistor is supplied to suit the gauge, but a regulator is the better option: resistors run hot, waste power and add a failure point at each gauge, whereas one regulator feeds the whole dashboard from a single clean supply (the 3A model runs up to 20 standard 52mm gauges, the 5A up to 38).
