HawkEye DepthTrax 1BX In-Dash Depth & Temperature Finder with Transom Mount Transducer

Depth and Temperature. One Clean Gauge. No Chartplotter Required.

The HawkEye DepthTrax 1BX is a self-contained in-dash depth and temperature finder designed for boaters who want reliable sonar readings without the complexity or cost of a full chartplotter. It fits a standard 2" gauge hole, reads depth to 600 feet, and displays both water and air temperature at the press of a button — all from a no-glare polarized LCD that's easy to read in direct sunlight.

The kit includes an AIRMAR® high-performance transom-mount transducer, so everything you need is in the box.

Key Features

• Dual Temperature Display — Reads both water temperature (via the transducer sensor) and air temperature (via the head unit sensor) independently; toggle between them with a single button press
• 600 ft Maximum Depth Range — Suitable for coastal, lake, and river applications across a wide range of vessel types
• AIRMAR® Transom-Mount Transducer Included — Ultra-sensitive, high-performance transducer ships with the unit; no separate transducer purchase required
• 3-Stage Advanced Warning System™ — Programmable depth alarm with three alert levels to warn you before reaching shallow water
• Programmable Keel Offset — Calibrate depth readings to display true depth below the waterline rather than below the transducer
• Algorithmic False-Reading Reduction — Onboard processing filters out interference and bottom clutter for cleaner, more reliable depth returns
• EasyTouch Programming™ — Intuitive button layout for setup and adjustments without a manual in hand
• No-Glare Polarized LCD — Clear readout in direct sunlight; SoftGlow™ backlit display and keys for low-light and night use
• Standard 2" Gauge Size — Drops into any standard 2" instrument panel cutout; includes both black and white face plates and trim rings to match your dash
• Selectable Imperial or Metric Readout — Switch between feet/°F and meters/°C to suit your preference

Best Use Case

The DepthTrax 1BX is the right choice for powerboat, pontoon, and aluminum boat owners who want a clean, dedicated depth and temperature gauge in their instrument panel — without adding a screen-based chartplotter or fishfinder. It's particularly well-suited for boaters who navigate shallow rivers, coastal flats, or lake systems where depth awareness and water temperature are the primary data needs.

It also works well as a secondary depth instrument on larger boats that already have a chartplotter, giving helm and co-pilot positions independent depth readouts without running additional display wiring.

Parts Desk Insights

Best for: Boaters who want a simple, reliable in-dash depth and temperature gauge that installs in a standard 2" hole and includes everything needed out of the box. The dual temperature feature (water + air) is a genuine differentiator over basic depth-only gauges — useful for anglers tracking thermoclines and for general boating situational awareness.

Installation note: The transom-mount transducer requires a clean, flat section of the transom below the waterline. Avoid mounting in areas with turbulence from strakes or the keel. Set the keel offset after installation to ensure depth readings reflect true water depth below the surface.

Depth alarm: The 3-stage warning system is programmable — set your three alert depths before departure when navigating unfamiliar or shallow water. This is one of the more practical safety features on a gauge this size.

Face plate options: Both black and white face plates and trim rings are included, so you can match the gauge to your existing instrument panel without ordering additional parts.
