HawkEye DT2BX-TM In-Dash Depth Sounder
Depth readings span 2.5 to 600 feet on a large in-dash display. The unit includes a transom mount temperature transducer with 30 feet of cable, enabling simultaneous air and water temperature readings. A 3-stage Advanced Warning System provides audible alarms, LED warning, and LCD indicators with one-touch alarm mute. Best for boaters who want an all-in-one, high-contrast readout with reliable depth and temperature data. Choose this if you need integrated temperature sensing and strong alarm capabilities in a single instrument.
Best for: coastal and inland boaters who value clear depth data with temperature readouts and robust alerting. Caution: ensure proper mounting for optimal signal and verify the transducer’s cable reach for your hull layout.
DepthTrax 2B Boat Mount In Dash Depth Finder
This model delivers uninterrupted depth readings from 2.5 to 600 feet on a large in-dash display, supporting up to 60 mph boat speed. It uses a 200 kHz transducer and includes a dual-mount transom or glue-in transducer capable of shooting through solid fiberglass hulls and up to 1/8-inch aluminum hulls. A 3-stage warning system includes audible alarm, ultra-bright red LED, and LCD indicators. Best for: boaters who need flexible mounting options and reliable deep-water readings. Caution: compatibility with hull material should be confirmed before installation.
Faria 13752 Chesapeake Depth Sounder
This is a classic 2-inch dial depth gauge with air and water temperature readings. The perimeter-lighted black dial with a contoured white pointer and polished stainless steel bezel offers a traditional, easy-to-read display. Best for: boaters who prefer a conventional gauge look and straightforward depth monitoring. Limitation: analog dials may be less precise in dynamic seas compared to digital readouts.
HawkEye DT2BX-TH In-Dash Depth Sounder
Includes a thru-hull transducer and provides instant depth updates, plus air and water temperature readings. The requirement of drilling a 2-inch hole in the boat bottom is a notable installation consideration. Best for: boats where through-hull transducers offer the most direct, stable signal. Caution: installation involves hull drilling and proper sealing to prevent leaks.
Hawkeye DepthTrax Edge Depth Finder
HD color display with a vibrant 360-nit screen and adaptive colors for visibility in all lighting. Features intelligent sonar with a 200 kHz transducer, 14-degree beam angle, and automatic range and sensitivity adjustments for accurate readings from 2.5 to 600 feet. The DepthTrax Plus app connectivity mirrors depth, water and air temperature, voltage, and VDR data to a smartphone, with built-in fish finder capabilities. Best for: tech-savvy anglers who want smartphone syncing and enhanced sonar features. Caution: ensure compatibility with your mobile device and network requirements.
Buying Guide
What gauge type should you choose? Digital displays offer clearer, faster depth and temperature updates, while analog dials deliver a classic look. Transom mounts are easier to install on smaller boats, whereas thru-hull transducers tend to provide more stable readings on larger hulls. Consider alarm features: models with audible and visual alerts help you stay informed during rough conditions or shallow depths. If you value app connectivity, look for units that sync with a smartphone to log data and view temperature trends over time.
How to pick the best for your use case:
- Freshwater fishing boats: prioritize clear digital depth with temperature readings and reliable alarms (HawkEye DT2BX-TM or DT2BX-TH).
- Rough seas and fast boats: a bright, large display with robust warning indicators is beneficial (DepthTrax 2B or DepthTrax Edge).
- Classic cockpit aesthetics: consider an analog option with a durable steel bezel (Faria 13752).
- Want mobile data and fish finder features? The DepthTrax Edge offers app connectivity for extended data access.
Frequently Asked Questions
- What is the typical depth range for these gauges? Most models cover 2.5 to 600 feet, with some analog options showing more limited scales.
- Do these gauges measure water and air temperature? Yes, several models include both air and water temperature readings.
- Can transom-mount gauges work with fiberglass hulls? Yes, some models include transom transducers designed to work through fiberglass and certain aluminum hulls.
- Is a thru-hull transducer harder to install? It requires cutting a hole in the hull, so it’s more invasive but can offer more stable readings in larger vessels.
- Are these gauges compatible with smart devices? Some models offer app connectivity to mirror data to a smartphone.
- What installation should I prefer? For easy upgrades, transom-mount options are common; for optimal readings on larger boats, consider thru-hull or integrated in-dash units.
