This is a Onyx 10 inch Side imaging touchscreen unit. It comes with a shoot through the hull transducer so you can use the unit at high-speeds to show the depth. And the Y cable to connect both Transducers to the unit This is $150 ad on and they are new in the box never mounted. 

The unit is in mint condition. 

I bought it to use on my boat but I traded boats and my new boat had a Lowrance side imaging already mounted in it so I decided to sell this Onix unit. It was only used about four months
