In order for the beam of the SI piezo to be pointing straight down ...the HDSI xducer needs to be tilted 60°...



You will also need a HB Dual Beam 200kHz/83kHz xducer and the AS SIDB Y cable for the system to be able to obtain depth...(because the 2d piezo will be pointing also 60° from vertical)...

The digital depth is used is the processing of the SI image...so it's important that the setup gets accurate depth readings..(from an additional 2d xducer)...

You can use any HB xducer that is capable of 200kHz/83kHz ...because the pin configuration in the "Dual Beam" leg of the AS SIDB Y cable will only connect the 2d piezo...
