DepthTrax 2B Boat Mount In Dash Digital Depth Finder
Depth readings cover 2.5 to 600 feet using a 200 kHz transducer. This unit is designed for dash mounting and supports installation on boats traveling up to 60 mph. It includes a dual transducer option that can be mounted through solid fiberglass hulls or through up to 1/8-inch aluminum hulls. An alarm system features an audible alert, a bright red LED, and LCD indicators for clear warnings.
Best for: Boat operators who want a large display, bright alarms, and flexible transducer mounting. The dual-mount/transom capability provides installation versatility for various hull types. Better for skippers who need fast, visible depth warnings at a glance.
Caution: Transducer installation may require hull penetration or through-hull mounting; ensure hull integrity and compliance with vessel regulations before drilling.
HawkEye DT2BX-TM In-Dash Depth Sounder
Delivers uninterrupted depth readings from 2.5 to 600 feet on a large in-dash display up to speeds of 60 mph. Includes a transom mount temperature transducer with 30 feet of cable. Features a 3-stage Advanced Warning System with audible alarm, LED warning light, and LCD indicators, plus one-touch alarm muting for convenience.
Best for: Boaters who want combined depth and temperature data with a robust warning system. This model is well-suited for anglers who rely on real-time environmental context, such as water temperature, alongside depth.
Caution: Temperature transducer line length is fixed to 30 feet; consider routing and space in your dash area to accommodate the wiring length.
Hawkeye DepthTrax Edge Depth Finder
Features a vibrant HD color display with 360-nit brightness, 2.5–600 ft depth range, and intelligent sonar that automatically adapts range and sensitivity for accurate readings. The DepthTrax Plus app connectivity mirrors depth, water and air temperature, voltage, and VDR data to a smartphone, and adds built-in fish finder capabilities for a connected boating experience.
Best for: Tech-forward boaters who value smartphone connectivity and a color display for quick readability in varied light. Choose this if you want integrated data presence on mobile devices and enhanced on-deck visibility.
Caution: App-based features require compatible devices and steady connectivity; ensure your phone’s compatibility and data plan coverage for real-time syncing.
Humminbird 407860-1 HDR 650 In Dash Digital Depth Sounder
This unit is supplied with a transom mount transducer and includes available bezel and face plate colors (white, black, chrome for bezels; white and black for face plates). It provides a straightforward, in-dash depth measurement solution suitable for boaters who want a simple, integrated display without extra frills.
Best for: Users seeking a reliable, no-fruss depth display that fits standard dash aesthetics. Suitable for boats where a clean, simple interface is preferred over extensive feature sets.
Caution: The package highlights color options rather than performance variances; verify that the included transducer matches your hull configuration before mounting.
Hawkeye Boat Depth Sounder Display Gauge DT2B
Part number DT2B; this 2-inch black display gauge is designed as a compact depth sounder option. It emphasizes straightforward, deck-level depth readings for small craft or as an add-on to larger navigation displays.
Best for: Small boats or as a supplementary gauge where space is limited and a compact display is sufficient. Good for integration as a secondary depth readout on smaller hulls.
Caution: As a compact gauge, it may not replace a full-depth sounder on larger vessels requiring large, illuminated displays for easy nighttime viewing.
HawkEye DT2BX-TH In-Dash Depth Sounder With Thru Hull Transducer
This model uses a thru-hull transducer and includes air and water temperature readouts. It supports in-dash viewing with the transducer penetrating the hull, a setup favored by boats that require deep readings without external protruding transducers.
Best for: Boaters who want depth and temperature data with a thru-hull installation, avoiding external transducers. Choose this if you have access to hull penetration and want a clean exterior profile.
Caution: Thru-hull installation requires drilling a hole in the hull; ensure watertight sealing and professional installation where needed.
Hawkeye in Dash Depth Finder w/Air & Temperature — Transom Mount
This in-dash depth finder includes air and water temperature readings with a transom mount setup. It provides a compact, straightforward depth gauge for dash installations on boats that prefer transom mounting over through-hull configurations.
Best for: Boaters who want a compact dash depth gauge with temperature readouts and a transom-mounted transducer. Suitable for vessels where hull penetration is undesirable or not feasible.
Caution: Transom-mounted transducers can be more susceptible to interference from hull makeup or mounting location; verify optimal placement to minimize noise and false readings.
Buying Guide: Key Purchase Considerations
- Depth range and precision: Most options cover 2.5–600 ft; verify that this aligns with your typical water depth and fishing depth needs.
- Transducer type and hull compatibility: Transom, thru-hull, and in-hull transducers have different installation requirements and hull impact. Choose based on boat type and ease of installation.
- Display features: Large, bright displays aid nighttime visibility. Consider HD color, brightness, and data presentation when choosing between dash-only and app-connected models.
- Temperature data: Models offering water and air temperature provide extra environmental context, helpful for locating fish and understanding conditions.
- Alarm and warning features: Depth alarms and audible alerts can improve safety in shallow areas or rapidly changing depths; check the alarm configuration and muting options.
- Smartphone connectivity: Some models offer app integration for real-time data mirroring and extended functionality. Ensure device compatibility and permissions.
