The C20-00131 is a class A spare compass in a wooden box, with a 125 mm flat card and 1° graduations. It is intended for service vessels and fishing, as a table compass or as a spare for a reflector compass, and the box protects it until you need it. An azimuth ring or sights are available as an option.

The C20-00132 is a sensor coil that is mounted under an external gimballed Autonautic compass, turning it into a Transmitting Magnetic Compass (TMC). The sensor measures the magnetic field and outputs the heading as an NMEA 0183 sentence; because it is aligned to the card, the heading read out always matches what you see on the compass. The sensor is mounted and calibrated on the compass at the Autonautic workshop and is ready for use as soon as it is powered.

The C20-00133 is an analog heading repeater with a rotating compass card in a 110 mm square housing. It displays the heading from an NMEA 0183 source, such as the C20-00132 compass sensor, at a second location on board: in the cockpit, at the chart table, or in the saloon. Mounting is surface-mounted without a cutout, requiring only a small cable hole, and the housing is waterproof according to IP68.

The C20-00135 is a class A periscope that allows you to read the C20-00128 compass from below, enabling the compass to be positioned outside the wheelhouse as a reflector compass. It features a wide field of view and its own 12/24 V lighting. The periscope is intended exclusively for the C20-00128.

The C20-00136 is an azimuth circle that you place on an Autonautic C20 compass to take accurate bearings. It fits the C20-00128, C20-00130, C20-00131, C20-00137, and C20-00138. Because the azimuth circle is calibrated to the compass at the factory, you should order it at the same time as the compass.

The C20-00137 is a class A steering compass on a bracket made of seawater-resistant aluminum, featuring a 125 mm card with 1° graduations that also allows for taking bearings. It complies with MED (Wheelmark), USCG, and UK MER standards, includes quadrantal correctors for steel hulls, and is ready for an NMEA 0183 sensor to drive repeaters, heading alarms, and navigation equipment. Installation via deck stand, on deck, bulkhead, or panel.

The B+C corrector set consists of two identical units: one corrects the B-deviation caused by the ship's longitudinal magnetic field, the other the C-deviation caused by the athwartships field. Each unit corrects 35 to 40° using movable alnico magnets in a black stove-enamelled aluminium housing. The set is designed for Autonautic C20 compasses and fits many other compasses.

The C3 is a compact surface-mount compass with a 65 mm spherical card, designed for RIBs, dinghies, and open sailboats. It mounts to a flat surface with three screws, requiring no large cutout, and the well-damped card remains steady even in choppy water and at higher speeds. Available with a black or white housing, both with a black compass rose.

The C4-00108 is a compact compass in a lacquered wooden box, intended for small boats, lifeboats, and rescue boats. The 85 mm flat card has a scale per 5° and is illuminated by a 1.5 V battery-powered LED. You can mount the box permanently on a horizontal surface or store it safely until it is needed.

The C4-00114 is a traditional compass in a varnished wooden box, intended for small boats, lifeboats, and rescue craft. The 100 mm flat card has a 2.5° scale and a lubber line; you mount the box on a horizontal surface or store it safely until needed. Lighting is optional for this model.

The C8 is a bracket compass for mounting on vertical surfaces or above eye level, such as the wheelhouse ceiling, a bulkhead, or the top of a console. The 85 mm conical card remains readable from multiple viewing angles, and the bracket makes it suitable for use where there is no space on the dashboard or where magnetic interference is an issue. Available with a black or white housing.

The C8-0027 is a bracket-mount compass for vertical installation, intended for workboats, lifeboats, and other motor vessels. You can mount it to the wheelhouse ceiling, against the roof edge, or on a side wall, and the 100 mm conical card remains easily readable while sitting, standing, or viewing from below at an angle. The housing is made of corrosion-resistant polymer with an impact-resistant, clear dome.

The C9 is a class B compass for bulkhead mounting, featuring an 85 mm conical black card and a built-in clinometer. It is designed for small commercial vessels, lifeboats, and pleasure craft, and is popular on sailboats with an enclosed or covered helm. The illumination operates on 12 and 24 V; available with a white or black housing.

This chronometer is gimbal-mounted in a beechwood box with a mahogany finish measuring 192 x 192 x 185 mm, with 18-karat gold-plated brass on all metal parts. The quartz movement comes from the German manufacturer U.T.S. and runs with a deviation of less than 1 second per day. The dial features Roman numerals and a second hand, behind 5 mm thick crystal glass with beveled edges.

The CHE is a large bracket-mount compass for deck installation, featuring a 140 mm flat card with 2.5° graduations. A B+C compensator system is built-in, the lighting operates on 12 and 24 V, and a protective cover is included. Suitable for larger sailing and motor yachts as well as medium-sized workboats; available with a black or white housing.

The CHE-0078 is a professional compass for mounting on the wheelhouse ceiling, suitable for coastal vessels, workboats, and large yachts. The 125 mm flat card has 1° graduations, rotates on a hardened steel pivot with a sapphire bearing, and is illuminated at 12–24 V. B+C correctors are built-in; quadrantal correctors for steel hulls are optional.

The CHH-0090 is a traditional lifeboat compass: an externally gimballed compass in a weatherproof ABS housing. The 100 mm flat card has 2.5° graduations and a lubber line, and the lighting is a 1.5 V waterproof LED unit that clips on and can be stored separately when not in use. The compass complies with IMPA code 330211 for 100 mm lifeboat compasses.

The CHH-0096 is a fully gimbaled magnetic compass in a traditional design, mounted on a bracket made of seawater-resistant aluminum with a deck base. The bracket can be positioned in any orientation and is instantly removable, making it suitable for sailboats and motorboats, and especially for boats with a closed cockpit. The fluid-filled card remains stable and is easy to read both day and night.

The Indic 175 is Autonautic's large aneroid barometer: 175 mm housing, 150 mm dial with black numerals on white. It tracks atmospheric pressure without power and is designed for pleasure craft, commercial shipping, and as a centerpiece on a wall at home or in the office. Available in chrome-plated or gold-plated (18-karat flash) finish, behind scratch-resistant mineral glass.

The Indic 175 clinometer, also known as a tilt meter, displays your boat's heel in degrees on a 150 mm dial with black numbers on white. Its large size ensures it remains easy to read from a distance and while in motion, at temperatures from 0 to 45 °C. Available in chrome or gold-plated finish, with a mounting ring on the back.
