A better Fishfinder?

When i was a kid on family car trips I would fantasize fishing in every. new body of water dove by,  still do actually.  But now you can do away with the fantasy part (fantasy and wonder are still the best parts for me)

I thought about this and even shared the drop bait idea with people and here we are.  Great idea and seems a no brainer for 21st century fish tech.  Bye bye kite fishing...........
