How to Connect 2 Garmin Fish Finders Together

Garmin fish finders are renowned for their accuracy and reliability in providing fishermen with valuable information about the underwater world. If you own two Garmin fish finders and want to connect them together, you can take advantage of their combined capabilities to enhance your fishing experience. In this article, we will guide you through the process of connecting two Garmin fish finders and answer some frequently asked questions to help you get started.

Before proceeding with the connection, make sure you have the necessary equipment. You will need two Garmin fish finders, compatible cables, and a power source such as a battery or a power bank. Once you have all the required items, follow these steps:

Step 1: Determine the type of connection
Garmin fish finders can be connected through the NMEA 0183 or NMEA 2000 protocol. Check the specifications of your fish finders to determine the type of connection they support. If both fish finders support NMEA 0183, you can proceed with the first method. If both support NMEA 2000, follow the second method. If they support different protocols, you may need additional adapters or converters.

Method 1: NMEA 0183 Connection
Step 2: Connect the NMEA 0183 cables
Use the NMEA 0183 cables to connect the two fish finders. One cable should be connected to the “NMEA Out” port of the first fish finder and the other end to the “NMEA In” port of the second fish finder. Ensure that the connections are secure.

Step 3: Power up the fish finders
Connect the power cables of both fish finders to a power source. This can be a battery or a power bank. Make sure the power source is fully charged and compatible with the fish finders’ voltage requirements.

Step 4: Configure the settings
Access the settings menu on each fish finder and enable the data sharing option. This will allow the fish finders to exchange information between each other. Follow the user manual of your specific fish finders for detailed instructions on how to enable data sharing.

Method 2: NMEA 2000 Connection
Step 2: Connect the NMEA 2000 backbone
Create a NMEA 2000 backbone by connecting the backbone cables to both fish finders. The backbone cables are typically labeled “NMEA 2000” and can be purchased separately if not included with your fish finders. Connect one end of the backbone cable to the “NMEA 2000 Out” port of the first fish finder and the other end to the “NMEA 2000 In” port of the second fish finder.

Step 3: Power up the fish finders
Connect the power cables of both fish finders to a power source. Ensure that the power source is fully charged and compatible with the fish finders’ voltage requirements.

Step 4: Configure the settings
Access the settings menu on each fish finder and enable the data sharing option. This will allow the fish finders to exchange information between each other. Consult the user manual of your specific fish finders for detailed instructions on how to enable data sharing.
