which screen frequency will be shown

For all the Elite 7 HDI owners. If a HST-WSBL transducer is on the back. Which frequency will be shown when changing to the transom transducer . Will the 83 or 200 frequency be shown? I dont think this unit will show 83 and 200 together.Thanks to all of the sonar experts....

Just bought one and installed it myself. From my limited experience with it, you hafta choose one or the other, but it will not display them both at the same time. You can select which one you wanna use from the sonar drop down menu.

Thanks for the reply. That's what i thought, but wasn't sure......
