SIM-IS42-DIG

Description

The Simrad IS42 is a compact digital instrument display for boats that want depth, speed, wind, heading, engine, battery, and autopilot information in a dedicated gauge. Its square 4.1-inch color screen fits a small instrument cluster, while NMEA 2000 and SimNet bring the data together. It is an instrument display, not a chartplotter or full fishfinder.

The optically bonded transflective LCD is designed for daylight viewing, and the 320 x 320 layout works well for pages built around large data fields. Active draw is listed at 50mA, rising to 130mA at full brightness, so it is easy to add to a 12V network. The IS42 can show depth from a compatible transducer, but it does not create sonar images itself. Up to four engine configurations are supported according to the supplied specification.

Key Features

4.1-inch square color display – Provides a compact instrument screen for key vessel data.
320 x 320 resolution – Suits large digital readouts and custom instrument pages.
NMEA 2000 and SimNet compatibility – Brings navigation and engine data to the display.
Depth, wind, speed, heading, and autopilot pages – Covers common sailing and powerboat instrument needs.
50mA active draw – Keeps the display’s network power demand low.

Who Is This For?

This NMEA 2000 instrument display suits offshore center consoles, sailboats, cruisers, and sport yachts that need a compact data repeater. It is not ideal for buyers seeking charts, radar, or sonar imaging; depth appears only when a compatible network sensor supplies the data.

Compatibility

Confirmed compatibility includes NMEA 2000, SimNet, direct NMEA 2000 data networks, J1939 engine gateways, compatible depth transducers, and multi-engine data configurations. The supplied information does not identify specific radar, autopilot, Garmin, Raymarine, or third-party sensor models. No named incompatible system was provided.

Warranty & Support

The supplied specifications do not state a warranty term. Confirm current Simrad warranty coverage before purchase.

The IS42 is a compact way to keep important boat data visible without using space on the main MFD. It is especially useful as part of a distributed instrument cluster. The trade-off is that it depends on the NMEA 2000 or SimNet network and connected sensors, so it cannot replace a chartplotter or sounder display.
