Using a Hummingbird 797 as portable unit
Ok folks, I purchased a used Hummingbird 797ci unit and before mounting it on my boat, I would like to check a spot on a bridge that don’t allow boats of any kind. That means float tubes, kayaks nor rowboats. Only way to do it is from on the bridge.
I was wondering if the side scan worked if the sending unit was still, or does it need to be moving even the slightest bit. I planned on rigging the sending unit up on a piece of PVC long enough to reach the water which is roughly 8’ below the bridge. Thank you for any help
