Depends on if you use your graph more when you are fishing or cruising and scouting. I personally liek to have a good graph at both the console and the bow.
Exactly, and honestly I have a hard time reading the 797 side imaging, to small IMO. If i had it on the bow, it would be so far away from me while I was standing, I honestly think it would be useless... I probably would never use it on the bow.I have fished the 797 for about a year and upgraded to the 1100 series. This is a no brainier if you have used side imaging. You MUST mount it at the console and the transducer at the rear. Side imaging only works between 3 and 6 MPH. Mounting on the bow with your trolling motor is useless except for standard down looking sonar and side imaging distorts every time you rotate the trolling motor. The 797 has an excellent GPS system that is worth it's weight at night from the drivers seat.
It has split screen for viewing side, down, GPS, mapping, and in any combination.
Side imaging is used to see the entire structure on a slow roll by, then position for the sweet spots and use any down looking unit at the bow.
