Will I be able to obtain high speed readings from my side imaging sonar?
Side imaging technology generally works
best in speeds up to 10 MPH. This will vary depending on the boat hull
and the location of the installation. Compact side imaging transducers like those that come with the 899ci HD SI are more conducive to faster speeds due to the smaller size.
the standard 2D sonar built into the side imaging transducer will work
to much higher speeds, high speed readings with the transom mounted HD SI transducers on faster boats are often limited by the turbulence that
occurs around the back of the boat. The HD Side Imaging transducers are especially sensitive to this so due to their size so we suggest the following solution.
The AS SI DB Y connects to the XP 9 20 and the AS 14 SI DB Y which connects to the XP 14 20, are Y cables that connect a dual beam transducer (for inside the hull mounting),and the SI transducer (mounted on the transom) to the unit. This solution will only work when shooting through the hull of a single layer fiberglass hull boat.
