DepthTrax 2B Boat Mount in Dash Digital Depth Finder - Large In-Dash

Our review of the DepthTrax 2B finds it is a practical choice for anglers and boaters who want a straightforward, reliable in-dash depth sounder with a large, easy-to-read display. The biggest reason to buy is its uninterrupted depth readings from 2.5 to 600 ft and an alarm system designed to draw attention when depth is critical, making it useful for navigation and fishing in varied conditions. Installation options and the polarized LCD mean it fits many small to mid-size boats, though glue-in mounting is limited to specific hull types.

Key Features

• Wide depth range: Provides continuous depth readings from 2.5 to 600 ft, giving confidence whether you are fishing shallow flats or navigating deeper channels.
• Large in-dash display: The biggest display available on an in-dash depth sounder makes numbers and icons easy to scan at a glance while underway.
• Dual transducer options: Includes a transom mount and a glue-in transducer that can transmit through solid fiberglass and up to 1/8 in aluminum for flexible installation on many hulls.
• Advanced alarm system: A 3-stage warning with an audible alarm, ultra bright red LED, and LCD indicators clearly signals shallow or alarm conditions for safer operation.
• Polarized LCD: A no-glare icon display with a storage sun cover allows spot-free viewing with or without sunglasses in bright daylight.
• Algorithmic signal processing: Built-in programming reduces false readings and improves accuracy, especially at higher speeds and during turns up to 60 mph.

Who It's For

The DepthTrax 2B is aimed at recreational anglers, small-boat owners, and coastal boaters who need a dependable, readable in-dash depth finder with both transom and glue-in transducer options. It suits those who run at higher speeds up to 60 mph and who value an obvious alarm if they approach shallow water.

Boaters with cored fiberglass or aluminum hulls thicker than 1/8 in should look elsewhere for a through-hull transducer solution, since the glue-in option is only for non-cored fiberglass or thin aluminum. If you need integrated sonar imaging or chartplotter features, this unit is focused on core depth measurement rather than mapping.

Pros & Cons

Pros

• Wide 2.5 to 600 ft depth range covers most recreational uses and offshore transitions.
• Large, polarized LCD with sun cover ensures readable icons and numbers in bright conditions.
• Dual transducer choice and algorithmic filtering deliver reliable, accurate readings at speed and during maneuvers.
• Clear 3-stage alarm system provides audible, visual LED, and on-screen warnings for safety.

Cons

• Glue-in transducer mounting is limited to non-cored fiberglass or aluminum thinner than 1/8 in, so not suitable for all boats.
• It is a dedicated depth finder without integrated mapping or fishfinder imaging features for advanced users.
