I know you have to be moving for the SI to work but what about the DI? If I had it mounted up front while I'm easing around spider rigging, at times I'm stationary, would the DI work while sitting still or do I have to be moving. It would be to easy to add another GPS puck and make a drop mount for another Transducer, then just move it to the front so I can use it there. Say have a split screen with the DI and regular FF view. I'd also have my way points I collected ready to go
