for 360 you want the biggest screen possible.........get the 12 and you will be glad you did...or at least 2 10's

also remember you can't run side/down imaging and 360 at the same time with both at 455hz you will get wagon wheel artifact on the 360....not as bad at 800hz......

the best 360 experience I have had IS WITH 2 helix 10 and top unit 360 front zoomed and lower unit 360 rear zoomed its like one giant virtual 20 inch 360. side imaging is useless when sitting still and 360 not too helpful unless trolling really slowwww
