Location: MN | Side Imaging transducers read SI, DI and 2D sonar all during off plane movement with a very high level of accuracy when adjusted to the conditions. It will work if you plug it in and use it, but you'll get more out of your electronics if you take a little time to learn them and tune them in for your use. It's like using a new reel out of the box without adjusting the drag or spool tension/brakes.
Side imaging is not intended for high speed readings (typical use is 3-5 mph and likely not more than 10mph). Due to the size of the transducers, significant water displacement occurs with all Side Imaging/Side Scan transducers at higher speeds creates a small air pocket underneath the transducer, causing you to loose depth and sonar readings. This is because sonar cannot read through air.
The solution? In reference to Humminbird SI units, per the original question, you can run a second transducer that will be dedicated to your hi-speed 2D sonar readings so that you will always have sonar and depth. Both the hi-speed transducer and Side Imaging transducer are connected to the unit via the use of a "AS SIDB Y" cable. A diagram is attached.
