Furuno FI70DSW Depth/Speed/Wind FI70 Package

The Furuno FI70DSW package combines a 4.1-inch color instrument display with an included DST-800 smart sensor for depth, speed, and water temperature. It is designed for boats that want those three readings visible at the helm without using a larger chartplotter page. The package connects through NMEA 2000 and keeps the installation compact for cruising and fishing boats.

The 320 x 240 QVGA display is easy to fit in a small instrument panel, while 700-nit brightness helps with daytime viewing. The display draws about 0.15A, and the complete package is listed at 0.25A, so the electrical load is modest. The DST-800 supplies depth, speed, and temperature data to the FI70. This is an instrument package, not a chartplotter, radar, or imaging fishfinder.

Who Is This For?

This NMEA 2000 depth speed temperature package suits cruisers, fishing boats, and sailboats that need dedicated basic instrument data. It is not ideal for buyers seeking charts, radar, wind data, or fishfinder imaging; the package focuses on the included DST-800 sensor functions.

Warranty & Support

Furuno provides a 2-year manufacturer warranty. The supplied specifications do not state warranty exclusions or service procedures.

The FI70DSW is the most complete basic instrument package here because the DST-800 sensor is included. It gives the helm depth, speed, and temperature without requiring a separate sensor purchase. The trade-off is its focused data set: it does not replace a chartplotter or fishfinder, but it makes a useful low-power companion to one.
