Installation Tip

Since this transducer does not come with a stopper, you will likely need to move your old one over. This video demonstrates how to quickly remove and install a transducer stop using pliers to avoid damaging the cable.

How to Install a Marcum Transducer Stop

This short tutorial is relevant because the transducer requires you to install a rubber stopper (not included) to hold the cable at the correct depth.

Frequently Asked Questions

What is the difference between the 8-degree and 20-degree cone?

20-Degree (Wide): Best for shallow water or searching for fish. It covers a larger area of the bottom.

8-Degree (Narrow): Best for deep water, fishing in heavy weeds, or when fishing near other sonar units. It provides better target separation and reduces interference.

Will this work with the new Lithium (Li) units?

Yes. The "Li" in models like the LX-7Li refers to the battery type (Lithium), not the sonar technology. The transducer port is identical, and this unit is fully compatible.

My current transducer is making a clicking sound. Is that normal?

Yes, a faint clicking sound from the transducer when the unit is powered on is normal; it indicates the crystal is transmitting sonar pulses. However, if your unit is not reading depth or shows a blank screen despite the clicking, you may need a replacement transducer.
