ForwardScan® Components

ForwardScan® transducers plug straight into Vulcan and Zeus³ series chartplotters, giving you immediate information about what lies ahead of your vessel. You can add ForwardScan® to Zeus², Zeus² Glass Helm and Zeus³ Glass Helm systems with a plug and play SonarHub Sounder Module. 


B&G Vulcan and Zeus³ chartplotters accept a ForwardScan® transducer plugged straight in.

ForwardScan® Transducer

ForwardScan® transducers are available in two sizes: Standard and Long Stem. Both come with a stainless steel thru-hull fitting


Zeus²,  Zeus² Glass Helm and Zeus3 Glass Helm MFDs need an extra plug and play SonarHub. Vulcan and Zeus³ MFDs will also need a SonarHub if a cable run greater than 12m is required

Look ahead

Explore poorly-chartered or unfamiliar waters confidently, avoid upcoming dangers or obstructions and set custom shallow depth alarms with B&G’s forward-looking sensor. With an effective range eight times the actual depth, ForwardScan® helps you avoid groundings or damage to keels and rudders while pinpointing the ideal spot for anchoring.

Look ahead with ForwardScan®

ForwardScan® is a powerful defence against running around, and an invaluable tool for locating secure sites to drop anchor.

The ForwardScan® transducer operates at 180 kHz to reduce interference from traditional 200 kHz echosounders, and provides:

• Maximum forward view of 8X your current depth e.g. at 3 m (10 ft) depth, see up to 24 m (80 ft) ahead.

• Nominal forward view of 4-5X your current depth e.g. At 3 m (10 ft) depth, see 12-15 m (40-50 ft) ahead.

Multifunction Display Integration

ForwardScan® connects quickly and easily to Vulcan* series displays via the Sonar port, with no additional hardware necessary. On the Zeus² and Zeus² Glass Helm modular systems, ForwardScan® may be connected via an optional SonarHub sounder module.

*Pre-2016 Vulcan 7 models (part number: 000-12213-001) are not ForwardScan® compatible.

Bottom Colour Tracking

Bottom Colour Tracking offers a solid 2D rendering of the bottom ahead of your vessel for an uncluttered, immediately understandable view. Make fast and well-informed navigational decisions, without needing to interpret the individual data points returned by the echosounder.

Heading Line View

Heading Line View integrates ForwardScan® depth data with the heading line displayed on the navigation page of your B&G multifunction display. The line is colour-coded in segments to represent deep, medium, and shallow water, with customisable depth ranges to suit your boat’s draught.

ForwardScan’s forward range scale is automatically synchronised with the length of the heading line: in split-screen ForwardScan®/Navigation view, the full distance from your vessel to the end of the heading line is represented in 2D on the ForwardScan® display. Quickly reconcile ForwardScan® data with charted depth and your present course, for a comprehensive understanding of what’s ahead.

Easy Installation

ForwardScan can be installed on almost any vessel, with a 50.8 mm (2 inch) stainless steel through-hull mount. The mount can accommodate 25.4 mm (1 inch) thick hulls at 12 degrees dead rise, or 19 mm (3/4 inch) hulls at 20 degrees.

An optional pre-install kit includes sleeve and blanking plug only, allowing boat-builders to provide ForwardScan as an upgrade option. A ForwardScan transducer can then be added by the dealer or customer, even once the boat has been splashed.
