Wi-Fish Sidae Imaging future

I have had a Raymarine Wi-Fish for about a year & live it. A large, touch screen using my iPad and for a very reasonable cost. I've had other wireless fishfinders (3 different brands) & they were all horrible. I cannot say enough good things about how simple this is to use or how flawlessly it connects (had trouble wiit ALL of the other units I have owned).

Having said all that, what would really rock would be a version that supports side imaging. Is there any plan to offer an add-on or another version of Wi-Fish?

Thanks for making solid products!
