Transducers

Fishing is all about knowing what’s below the surface. That’s where transducers come in. They’re the key to turning sound waves into a clear view of the underwater world.

Here in Australia, there’s a transducer for every type of boater. Whether you’re chasing fish in the shallows or heading out deep, there’s a perfect option waiting for you. Let’s make choosing one easy.

Why Do You Need a Transducer?

A transducer gives you a clear view of what’s below the surface. It’s perfect for finding fish, checking depth, and spotting underwater structures, making your time on the water easier and more enjoyable.

It works by using sonar to scan beneath your boat. The transducer sends out signals that bounce back when they hit objects. These signals are then turned into detailed images on your fishfinder screen.

How to Position a Transducer

Getting the placement right makes all the difference.

• Transom-Mount: Set it just below the hull so it stays in the water, even when you’re moving fast.
• Thru-Hull: Place it near the keel where the water flows smoothly.
• In-Hull: Stick it on solid fiberglass and keep it free from air bubbles for the best signal.
• Portable: Make sure it’s fully under the water to get accurate readings.

Can You Use Two Transducers on One Boat?

Yes, you can run two transducers on the same boat, but be mindful of potential interference. To minimize this, choose transducers that operate on different frequencies, such as pairing a 50 kHz unit with a 200 kHz one. This frequency separation helps prevent the signals from clashing. Additionally, mounting them on opposite sides of the transom can further reduce the chance of interference.

Using two transducers lets you get more out of your fishfinder. You can cover different depths with varied frequencies, like 50 kHz for deep water and 200 kHz for shallow. It’s also handy for combining sonar with speed or temperature readings, or even as a backup in case one fails. This setup is great for fishers who want detailed data or fish in different environments.

Will a Transducer Work Out of Water?

No, transducers need water to work. Without water, the sonar waves don’t transmit properly, and the unit could overheat or get damaged.

Frequency in Transducers

The frequency of your transducer makes a big difference in how it works.

• Low kHz (50): Great for deep water. It reaches further but doesn’t show as much detail.
• High kHz (200): Perfect for shallow spots. It gives sharper, clearer images of fish and structures.
• Dual-Frequency: This is the best of both worlds. It’s versatile enough to handle both shallow and deep waters.
