Overview

The Garmin 010-01870-00 is a 4.3-inch GPS fishfinder packaged with a dual-beam transom-mount transducer for traditional sonar. It runs on 12 to 20 Vdc, uses a 3 A fast-acting fuse, and carries an IPX7 water rating for rain, spray, and quick washdowns.

On the water, it gives you CHIRP traditional sonar for separating fish from structure, plus built-in GPS for waypoint marking, simple routes, and a speed readout when you are trolling. Quickdraw Contours lets you build your own contour maps as you drive, saving maps with 1 ft contours for up to 2 million acres.

This is a good fit for smaller boats that need a straightforward sonar and GPS setup at the helm, or as a compact second screen where space is tight.

Installation and setup

Mount the display where you can reach the keys and see the screen while standing or seated, then use the tilt and swivel bracket to fine-tune the viewing angle. Leave enough clearance behind the unit for the cable bend radius and for removing the connectors later for service.

For the transducer, plan the transom run so the face sits in clean water at speed. Keep the cable away from ignition wiring and high-current bundles when possible, and secure it so it cannot chafe on the transom, splashwell, or trailer hardware.

Electrical and system integration

Connect to a clean 12 V supply with the in-line fuse in place, and tie grounds back to the same negative buss used by your electronics. If the unit ever powers on and off unexpectedly, voltage drop at the connector is usually the first thing to check.

User data such as waypoints can be shared with compatible Garmin units using the data wires on the power cable or a user data sharing cable when the devices are installed too far apart for a direct connection.

Use on board

For inshore and freshwater fishing, the GPS makes it easy to return to rock piles, channel edges, docks, and ramps, while Quickdraw Contours builds a bottom picture of the areas you actually run. It also works well on skiffs and aluminum boats where a compact head unit keeps the console uncluttered.

Maintenance and care

After saltwater use, rinse the unit and transducer with fresh water and avoid aiming high-pressure spray directly at connectors. Periodically inspect the transducer face for growth or nicks and check the cable routing points for wear, especially where the cable passes through the transom area.
