ForwardScan® Forward-Looking Sonar Long Stem Transducer & Housing Kit

Confidently navigate in shallow or poorly charted waters with ForwardScan® Sonar.
The ForwardScan Long Stem Transducer features an extended stainless steel through-hull mount and specially designed fairing block to accommodate hulls up to 1 7/8" in thickness and up to 28° deadrise.
ForwardScan® provides forward-looking, two-dimensional sonar views of the bottom ahead of your boat. ForwardScan® is a powerful defense against running aground, and an invaluable tool for locating secure sites to drop anchor.
The ForwardScan transducer operates at 180kHz to reduce interference from traditional 200kHz sonar, and provides a maximum forward view of eight times your current depth, so you’ll see up to 80' ahead in water 10' deep.
Simple to install using a standard 2"dia. stainless steel thru-hull housing, the transducer plug can be removed for servicing with the boat in the water. Transmits and receives up to 10 times faster than previous forward-looking systems, and networks with compatible displays.
Key Features
- Simrad ForwardScan® Technology: ForwardScan provides forward-looking, two-dimensional sonar views of the bottom ahead of your boat. In shallow, unfamiliar, or poorly-charted waters, ForwardScan is a powerful defense against running around, and an invaluable tool for locating secure sites to drop anchor.
- Bottom Color 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 sonar.
- Heading Line View integrates ForwardScan depth data with the heading line displayed on the navigation page of your Simrad multi-function display. The line is color-coded in segments to represent deep, medium, and shallow water, with customizable depth ranges to suit your boat’s draft.
- Intuitive Information Display: ForwardScan’s forward range scale is automatically synchronized 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.

Comments about ForwardScan® Forward-Looking Sonar Long Stem Transducer & Housing Kit by Simrad | Electronics & Navigation at West Marine
I purchased the long stem forward-looking sonar transducer based upon specifications that indicated that it could be mounted in a hull 1.5 in in a dead rise of up to 28 degrees. Upon cutting my fairing block to the correct angles and inserting the transducer thru hull it is very apparent that this device is about two and a half inch too short it has a measurements of 4.5 in in order for it to accommodate a dead rise of 28 degrees it would need to be 7.5 in in length. Do not purchase this item unless you are ready to build a custom blister on the bottom of the boat. Basically it doesn't work as advertised

- Q
I have an Ingrid 38 double ended. The slope of the hull is about 45 degrees were it is suitable to mount the transducer. How is the fairing block faired to fit the 45 degree hillside? How can I see both transducers? Down and forward scan. How can I switch between the transducers down and forward scan? Do I need to connect the down sonar to my cockpit mfd and have the forward scan connected to my navigation mfd. and if I do that can I see the forward scan I the cockpit?
- Asked by Cai
- Verified Reply - West Marine Customer ServiceThe fairing block is cut in half at the proper 45-degree angle so half is mounted outside the hull and the other half is mounted inside the boat. How you look at the transducers will depend on how you have connected them and selecting the proper source for the transducer. Yes, you can connect one transducer to one display and the other transducer to a second display.Was this answer helpful to you
- Q
Is this compatible with the EVO 3 and what about the installation in an AIREX Cored hull
- Asked by John
- Verified Reply - West Marine Customer ServiceYes, the Simrad ForwardScan Forward-Looking Sonar Long Stem Transducer & Housing Kit is compatible with the Simrad NSS evo3 displays. You may install a through hull transducer in an Airex cored hull, but you must follow the instructions for dealing with the foam core issues.Was this answer helpful to you
