SKU: 010-01961-10 Category:

Get extremely clear probe images of objects, structures and fish that are under and on the sides of your boat thanks to this 12-rod transducer that is mounted through the stainless steel wheeled hull.

This transducer with built-in fast-response temperature sensor has a power of 500 W per unit (1,500 W in total), a depth of 750 ft (DownVü) and 500 ft left and right (SideVü) and a CHIRP operating frequency of 455/800 kHz¹;. It is suitable for helmet strut angles of less than 5 degrees. Link it with your GCV™ 10 scanning probe module.

Includes translator with stainless steel wheel, fairing block, insulation bushings and plate, extension cable, assembly components and installation instructions. Follow the instructions carefully to avoid damage to the boat.

¹CHIRP frequency bandwidth: 445 to 475 kHz and 805 to 840 kHz.

FAQs

What is the main installation consideration for thru-hull mounting?

Thru-hull installations require drilling a hole through the hull, which increases installation complexity and needs careful placement.

What installation guidance is given for optimum performance?

Install all transducers according to the included installation instructions to achieve best possible performance.

What is the key to optimal transducer performance during installation?

Install transducers according to the included instructions to ensure best performance.

Why might installation be more complex for external thru-hull transducers?

Placement is more complex for external models due to fairing installation and orientation requirements.

Where should thru-hull transducers ideally be located on the hull?

Install external thru-hull types with a fairing in clean water, forward of propellers and running gear.

When should a thru-hull transducer pair be used?

A thru-hull pair is recommended for mounting a SideVü transducer where the deadrise exceeds 5 degrees.

When is a fairing required for a thru-hull transducer?

A fairing is usually required for external thru-hull transducers to ensure the transducer face is parallel to the waterline.

Are there thru-hull options for different hull materials?

There are thru-hull transducers available for every hull material, ensuring broad compatibility.

Do thru-hull transducers sit flush with the hull?

Flush thru-hull transducers are designed to sit flush or nearly flush with the boat hull, minimizing drag.
