Fish Finders & Marine Sonar — Garmin, Humminbird & HawkEye Units

This collection covers the full range of fishfinder and depth sounder options available at Sonark Marine — from simple handheld depth finders for kayaks and small boats all the way to advanced 360-degree imaging sonar for serious tournament anglers.

Garmin STRIKER 4 — Entry-level CHIRP fishfinder with built-in GPS chartplotter. Includes a 77/200 kHz transducer with both transom and trolling motor mounts. CHIRP sonar delivers sharper target separation and more distinct fish arches than traditional single-frequency units. GPS allows you to mark fishing waypoints and navigate back to productive spots.

Humminbird HELIX 5 DI G2 — Mid-range fishfinder with Down Imaging sonar for photo-like views of bottom structure and fish. The G2 platform features a 5-inch color display with updated interface. Down Imaging is particularly effective for identifying specific structure types — rocks, vegetation, timber — that traditional 2D sonar shows as blobs.

Humminbird MEGA 360 Imaging — Advanced 360-degree sonar that sweeps a full circle around the boat, showing fish and structure in all directions simultaneously. Designed for tournament bass fishing and detailed shallow-water structure mapping. Requires a compatible Humminbird head unit.

HawkEye FishTrax 1C — Compact boat-mount fishfinder with HD color display showing depth, water temperature, and fish position indicators. Straightforward operation — no GPS or advanced sonar, just reliable fish detection and depth reading for recreational anglers.

HawkEye FishPod 10BX — Bluetooth-connected boat-mount fishfinder that pairs wirelessly with your smartphone or tablet. Displays sonar readings on the FishTrax app. No screen on the unit itself — the phone is the display. Good option for anglers who want sonar without a dedicated mounted unit.

HawkEye DepthTrax 1H — Handheld castable depth finder that also reads water temperature. No permanent mounting required — cast the transducer to check depth before anchoring or positioning the boat. Ideal for kayakers, dock fishing, and scouting unfamiliar water.
