Compasses, level and fuel indicators, binoculars, voltmeters and nautical clocks for sailing and powerboating. To choose, start with the function — navigation or system monitoring — then check compatibility with the installation and electrical signals of your system.
How to choose compasses and marine instruments
The category includes two distinct families: navigation instruments (compasses, binoculars, clocks, hygrometers) and onboard monitoring instruments (level, fuel, temperature, voltmeter, and tachometer gauges). The correct choice depends first and foremost on the intended use, and then on the specific technical characteristics.
Compasses: mounting type and readability
Compasses are divided into binnacle compasses (flange-mounted or recessed into the binnacle), wall-mounted compasses, and bearing compasses. The dial diameter determines readability from a distance and the required hole size. The rose graduation (typically every 2° or 5°) affects reading accuracy during maneuvers. Plastimo, Riviera, and
Level and fuel gauges: sensor resistance
Analog level gauges work in conjunction with a sensor. The critical parameter is the resistance range: the two most common standards in marine applications are 240–33 ohms and 0–180 ohms. The gauge and sensor must share the same standard; otherwise, the reading will be incorrect. Tubular sensors are also selected based on their length, which must match the useful height of the tank. VDO, Wema, and Can-SB are the leading brands for this type of instrument.
Temperature and pressure gauges
For monitoring the engine and systems, temperature and pressure gauges require compatible sensors in terms of signal type and thread. Before purchasing a replacement gauge, check the brand and code of the sensor already installed, or replace the gauge and sensor together.
Marine binoculars
Marine binoculars are characterized by their waterproof design and often by an integrated compass, which is useful for bearings. The 7x50 configuration is the established standard: the 7x magnification limits shake caused by the boat's motion, while the 50 mm objective lens ensures brightness even in low light. Plastimo and Steiner offer models with an illuminated reticle compass. Compact monoculars with a compass are an alternative for those seeking a smaller size.
Panel instruments and marine clocks
Digital voltmeters, hour meters, tachometers, and multifunction panels complete the onboard instrumentation. Barigo is the leading brand for marine clocks, barometers, and hygrometers. Vion offers column-mounted and integrated panels. Always check the supply voltage and the mounting hole dimensions before purchasing.
