Can You Use Two Fish Finders From the Same Transducer?
Many anglers have asked whether they can use two fish finders from the same transducers. It is possible to connect two fish finders to the same transducer by using a Y-cable or a special dual-frequency transducer. This solution has many advantages, but it can also be inconvenient. fish finders for bank fishing
One problem associated with using two fish finders from the same transducers is the interference they cause. Although there are some modern fish finders that can work together on the same frequency, many manufacturers recommend that you use two transducers with different frequencies. You can also run two fish finders on different sides of your boat to avoid interference.
Transducers come in two different shapes: cylindrical and cone. Cylindrical ones emit a circle-shaped beam of sonar waves around the transducer. This feature helps you focus your fishing efforts in one area of the water. Cylindrical ones are better suited for fishing in shallow water, while cone-shaped ones are better for fishing in deep waters. Each fish finder is calibrated for its type of transducer, so make sure you have the correct transducer for your fishing needs.
Standard sonar uses 200 kHz transducers, which can cause interference if two units are used on the same boat. This interference will appear as rain on the screen, and will interfere with the signals sent out by the fish finders. The longer the distance between the two transducers, the more interference there will be.
Low frequency transducers use a wider beam and are more sensitive. This allows them to find large objects and structures where fish hide. In addition, lower frequency transducers may not work as well if you are fishing in shallow waters. For maximum clarity, consider using a higher-frequency transducer.
For mid-sized boats, a combination of a fish finder and chartplotter makes sense. You can use the fish finder for navigation to your fishing grounds, or you can view the chartplotter separately. A common way to convert a chartplotter into a combo unit is to install a “black box” sounder module. These modules can be attached to the transducer.
The two transducers can be connected using a User Data Sharing cable. The two devices will then share waypoints. The two devices should be mounted close to each other. The cable will connect the devices over blue and brown wires. Once connected, the two devices will share the same user data.
