Der Active Imaging kann im Downscan nur 455kHz.

2 in 1 (part 000-14490-001)
The number 2 in the name relates to the transducer having two sets of ceramic elements. One set for SideScan and one set for DownScan. There is no 2D-element in 2 in 1, so you need a separate transducer for 2D. The SideScan-elements produce 455 or 800 kHz while DownScan is 455 kHz.
