FAQs: Installation and Setup of Garmin Echomap Ultra 122sv with LiveScope

While it’s possible to power both the Garmin 122 and the LiveScope black box with the same 10-gauge wire, it’s not typical due to the black box’s usual distance from the display unit. Additionally, you should install a switch on the power lead to the black box to prevent constant battery draw. It’s common to wire each unit individually, and a 12-gauge wire is sufficient for the LiveScope black box.
The transducer cable provided is 20 feet long. The network cable connecting the black box to the Garmin 122 unit is typically 6 feet long, but longer cables are available if needed.
Yes, both the Garmin 122sv and the LiveScope black box are factory fused at 7.5 amps each. Although they don’t typically draw that much power, they do require a few amps each.
To use LiveScope with the Garmin Echomap Ultra 122sv, you will need the complete system, which includes the black box and the LVS 34 or 32 transducer. The type of transducer, such as the LVS 34, can be chosen based on your fishing preferences, such as bass fishing or crappie fishing.
