I have a e97 unit for sale, I know just a little bit about them, it's a 9 inch touch screen unit, it is wifi and bluetooth, so not only can you control if from your phone or iPad you can view data on other devices. You can also (purchase separately) connect a thermal or analog camera to the unit and view. I have the unit, power cable, bracket for mounting and adapter cable to use Minnkota universal transducer. I do not have any other transducers. I actually have two of these units, selling one now but if someone wanted both we could work something out. $1,100 for the unit.
