Overview

The Garmin 010-01550-00 is a GPS fishfinder with a 3.5 in color display (480 x 320) and traditional CHIRP sonar using the included 77/200 kHz 4-pin transducer. It is rated IPX7 for water exposure at the helm and runs on 10 to 20 V DC.

On the water, it lets you mark waypoints where fish are holding, record tracks, and navigate back using the waypoint map. It also includes a flasher view for vertical jigging and an on-screen speed readout to help keep trolling speed consistent.

Key features

• 3.5 in HVGA color display with 480 x 320 resolution
• Included dual-beam CHIRP 77/200 kHz transducer (4-pin) with a 20 ft cable for typical helm-to-transom runs
• 200 W RMS transmit power (1,600 W peak-to-peak) with a maximum rated depth of 1,600 ft in freshwater and 750 ft in saltwater
• Built-in GPS with waypoint map, supporting up to 5,000 waypoints, 50 tracks, and 100 routes
• Sonar history rewind and Smooth Scaling graphics so you can scroll back and mark a spot you passed over
• Built-in flasher view plus speed display for trolling, jigging, and stationary fishing
• 12 V boat wiring with a recommended 3 A fuse; max current draw 1 A within the 10 to 20 V DC input range
• Mounting support for tilt/swivel bracket or flush mounting, with an IPX7-rated housing for spray and washdowns

What's included

• STRIKER 4 display unit
• Dual-beam 77/200 kHz transducer (4-pin)
• Transom mount and trolling motor mount hardware for the transducer
• Tilt/swivel mounting bracket
• Power cable
• Documentation

Installation and setup

Mount the display where you can see it while running and fishing, and keep it at least 25 cm (9.84 in) from a magnetic compass. If you flush-mount, confirm you have clearance behind the panel for the connectors and cable bend radius.

Power is a straightforward two-wire hookup on most 12 V boats. Protect the circuit with a 3 A fuse, keep connections clean and dry, and route the power lead away from ignition wiring and other high-current conductors when possible. On 24 V systems, use a DC-DC converter to supply clean 12 V power within the 10 to 20 V DC input range.

The included transducer can mount on the transom or a trolling motor. A clean installation with the correct transducer height, solid bracket attachment, and a protected cable route is what makes the sonar perform well at idle and on plane.

Compatibility and fit

This unit uses a 4-pin transducer connection and comes with the matching transducer, mounts, and cable. The on-screen map is a waypoint map that shows your position in relation to saved waypoints and recorded tracks.

Waypoints and routes can be shared between compatible STRIKER and echoMAP devices by connecting the blue (Tx) and brown (Rx) wires in the power cable and enabling user data sharing in the menu. When sharing is not used, those wires can be left disconnected.

Use notes

This is a good match for skiffs, bass boats, small center consoles, and kayaks that have a 12 V accessory battery and want sonar plus GPS marking without moving up to a larger display. Depth performance depends heavily on transducer placement, bottom type, and water conditions, so take the time to dial in the transducer install if you fish offshore or in deeper water.

Maintenance and care

Rinse salt spray off the display and transducer after a trip and keep the transducer face free of growth. Periodically check the transducer bracket hardware and cable tie points for loosening from vibration.
