HawkEye DT2BX-TM In-Dash Depth Sounder with Temperature
The HawkEye DT2BX-TM provides depth readings from 2.5 to 600 feet on a large in-dash display. It includes an air and water temperature sensor with a 30-foot cable transducer. Best for boaters who want an all-in-one depth and temperature package with an audible alarm and a bright LED warning light. The system supports a 60 mph speed threshold and uses a three-stage alarm to clearly signal depth risk. A transom mount transducer is included for quick setup.
Best for: boaters who want an in-dash depth gauge with integrated temperature data and robust alarm features. Choose this if you favor a large display and a single unit that combines depth, temperature, and alarms in one package.
Caution: The device relies on a transom transducer; ensure your mounting surface accommodates the transom cable routing and that you can run the 30-foot cable without interference.
Faria 13752 Chesapeake Depth Sounder (Transom Mounted)
The Faria 13752 Chesapeake depth sounder features a perimeter-lighted black dial with a contoured white pointer and polished stainless steel bezel. It’s a traditional, aesthetically pleasing option for boat dashboards that favor a classic look. This model excels in straightforward depth indication with a clean dial and durable stainless construction, making it suitable for boats where style and reliability matter.
Best for: planners who want a visually clear dial and a proven transom-mounted setup. Opt for this if you prefer a timeless instrument with durable materials and a refined finish.
Caution: This model emphasizes dial design and may have fewer digital features than modern digital gauges; confirm it covers your preferred depth range and installation needs before purchase.
Hawkeye DepthTrax In-Dash Digital Depth Gauge
The Hawkeye DepthTrax is an in-dash digital depth gauge with a transom-mount option. It offers user-selectable feet or meter readouts and automatic memory retention for all user settings. This model is ideal for boaters who prefer digital clarity and want to preserve custom alarm configurations across sessions. The one-touch alarm muting adds convenience during active navigation or fishing.
Best for: anglers and nav-focused users who value memory settings and flexible unit readings. Choose this if you want quick muting and consistent depth logging across trips.
Caution: Digital interfaces may require occasional calibration or screen readability in bright sun; verify display visibility under your typical lighting conditions.
HawkEye DT2BX-TH In-Dash Depth Sounder (Through Hull)
The DT2BX-TH combines depth with air and water temperature readings and includes a through-hull transducer. The package is designed for boats requiring a robust installation without a transom mount, though it requires a 2″ hole in the hull. Depth updates are fast, and temperature readings provide immediate environmental context for water conditions.
Best for: boaters with compatible hull types (where through-hull installation is feasible) who need both depth and temperature data displayed in one unit. Choose this if you prefer a compact through-hull setup over transom mounting.
Caution: Through-hull installation is invasive; ensure you’re prepared for hull drilling and consider professional installation if unsure about hull integrity or warranty implications.
Faria 13852 Chesapeake Depth Sounder (Transom)
The Faria 13852 model features a polished stainless steel bezel with blue and black graphics for a stylish dashboard presence. It’s a transom-mounted unit that highlights the classic look with a modern dial and reliable depth indication, complemented by air and water temperature readings when connected to the appropriate transducer. This option suits boats prioritizing both durability and a refined aesthetic.
Best for: sailors or boaters seeking a durable transom-mounted gauge with an elegant dial. Choose this if you want a blend of visual appeal and dependable depth/temperature data.
Caution: As with other transom setups, ensure the mounting location can accommodate the transducer cable routing and that the installation aligns with your vessel’s hull design and clearance requirements.
Buying Guide: Depth And Temperature Gauges For Boats
What should you consider when selecting a depth and temperature gauge?
- Mounting style: In-dash, transom-mounted, or through-hull. In-dash offers integrated displays; transom and through-hull require external installation considerations and potential hull work.
- Measurement range: Ensure the depth range covers your typical water depths and is compatible with your boat’s operation environment.
- Temperature readings: Decide if you need air, water, or both temperatures. Some models include a combined depth and temperature sensor; others require separate transducers.
- Alarms and notifications: Look for audible alarms, LED indicators, and muting options to avoid nuisance alerts while anchoring or navigating.
- Display readability: Large digits and contrasting displays improve readability in bright sun and rough seas. Consider digital vs. analog dial preferences.
- Power and memory: Some units retain user settings automatically and offer memory for alarms or thresholds, which is helpful for repeat trips.
- Installation considerations: Transom mounts require mounting strength and cable routing; through-hull transducers demand hull drilling and may affect vessel integrity or warranty.
Frequently Asked Questions
- Do depth gauges measure only depth, or can they measure water temperature too? Some models measure both depth and water temperature; others provide air temperature or require a separate transducer for water temperature.
- Is a through-hull transducer better than a transom transducer? Through-hull transducers can offer accurate readings but require hull modification; transom transducers are easier to install but may be more prone to interference in some setups.
- Can I use the depth gauge for commercial or saltwater boats? Yes, most models are designed for marine use, but verify corrosion resistance and compatibility with your vessel type and water salinity.
- Will alarms drain my boat’s power quickly? Most units are designed to be energy-efficient; alarms are typically low power, but check your model’s specifications for long trips.
- How accurate are these digital depth readings? Depth gauges provide reliable readings when properly installed and calibrated, with accuracy depending on transducer quality and mounting.
- Do these devices require professional installation? Some models are beginner-friendly, especially transom-mounted units; through-hull installations may benefit from professional help.
