The DepthTrax 2B provides uninterrupted depth readings from 2.5 to 600 feet on a large in-dash display, suitable for high-speed boats up to 60 mph. It uses a 200 kHz transducer and supports dual-mount options: transom or through the hull for solid fiberglass and thin aluminum hulls. This model includes a three-stage Advanced Warning System with an audible alarm, a bright LED warning light, and LCD indicators. Best for serious offshore or coastal anglers and recreational boaters who want a bright, clear readout and strong alarm cues.

  • Best for boats needing a large, high-contrast display.
  • Better for vessels where hull-through installation is preferred.
  • Consider the hull material to ensure the transducer choice matches the installation.

Caution: Ensure proper transducer installation to prevent erroneous readings, especially on metal or very thick hulls.

This Hawkeye in-dash depth finder includes an air and water temperature readout and is described as a transom-mount version of the DT2BX-TM line. It supports depth tracking alongside environmental data, which helps calibrate readings and plan trips in variable conditions. Best for boaters who want integrated weather- and depth-insight in one gauge. A limitation is that temperature data requires proper sensor installation for accurate readings.

  • Best for boats needing both depth and water temperature data.
  • Choose this if you prefer standard transom-mounted deployment.

Caution: Temperature accuracy depends on sensor placement and water exposure; improper mounting may reduce reliability.

Part Synergy Replacement for Hawkeye In-Dash Depth Finder

This option is ideal for owners upgrading or replacing a failing transducer without changing the entire unit. Best for users of Hawkeye in-dash systems who want a compatible, cost-effective transducer solution. Limitation: The depth range is narrower than some newer units, so ensure it meets your boating depth needs.

  • Best for Hawkeye system owners needing a replacement transducer.
  • Better for mid-range depth requirements on traditional setups.

Caution: Not a full unit replacement; verify compatibility with your specific Hawkeye model before buying.

Buying Guide

What to consider when choosing an in-dash depth finder

  • Depth range and transducer compatibility: Ensure the unit supports the maximum depth you encounter and matches your hull or transom installation type (in-dash, transom, or through-hull).
  • Display size and readability: A larger, bright LCD is easier to read on the move, especially in direct sun or nighttime conditions.
  • Power requirements: Most models run on 9–32 V DC. Verify that your boat’s electrical system meets the unit’s needs.
  • Mounting method: In-dash units save space but require proper cutouts; transom-mount options are easier to install on older boats.
  • Additional features: Temperature sensing, memory retention, alarms, and dual transducer support add utility but may increase cost.
  • Durability and weather resistance: Look for IP ratings and corrosion-resistant constructions for marine environments.

How to compare 5 common options

  • Best overall depth range: DepthTrax 2B offers wide 2.5–600 ft depth capability and a bright display, suitable for coastal to open-water boating.
  • Best value for dash integration: Estink and Srum models provide dash-ready solutions at lower price points with solid basic depth reading capabilities.
  • Best for integrated environmental data: Hawkeye DT2BX-TM versions include temperature readings for more complete environmental awareness.
  • Best for replacements and upgrades: Part Synergy transducers are ideal when upgrading or repairing Hawkeye systems without changing the whole unit.

Installation and maintenance tips

  • Follow transducer mounting guidelines precisely to minimize noise and erroneous readings.
  • Periodically inspect wiring and seals to prevent water intrusion and corrosion.
  • Calibrate alarms and units to account for hull movement and water conditions in your typical boating routes.

Frequently asked questions

  1. What is an in-dash depth finder? A device that provides depth measurements directly on a dash-mounted display for quick, at-a-glance readings while underway.
  2. Do all in-dash depth finders require hull-mounted transducers? No, some use transom-mount or through-hull transducers depending on hull type and installation.
  3. Can depth finders measure water temperature? Many models include a temperature sensor to supplement depth data, aiding navigation in variable conditions.
  4. Is a larger display always better? Generally, yes for readability at high speeds, but it depends on your cockpit space and mounting options.
  5. What maintenance is needed for depth finders? Regularly inspect seals, clean the display glass, and verify transducer integrity to maintain accuracy.
  6. Can I replace just the transducer? Yes, many brands offer replacement transducers, but ensure compatibility with your existing display and model.
