Buy the biggest screen you can afford....most prospective SI buyers do not realize the "structure" image size ratio of SI images vs 2D images...
for example...I have the HB 1197 (10 in screen)...a
brushpile that shows as the size of a golfball on the 2D images shows as the size of a quarter on the SI image...now take that
same brushpile on a 798 (5 in screen) ...that
very same brushpile is the size of dime on the 2D image shows as the size of a pea on the SI screen...therfore I say again...buy the biggest screen you can afford......
HB or L is personal choice...both will give you great images...
HB SI has less hardware...head unit / 1 xducer / gps antenna...
Lowrance SI has more hardware...head unit / 2 xducers / LSS-1 module / GPS antenna...
Best place to mount the hardware depends on what you expect to use the SI for...
Bass fishin and lookin for structure with the big motor would lend towards a console (head unit) /transom (xducer) mount..
Trolling and lookin for structure with the trolling motor would lend towards bow (head unit) / trolling motor (xducer) mount...
AS wiskers stated it is somewhat difficult to get good images with the xducer on the TM because the SI xducers are designed to operate in a straight line with the boat path...turning the TM with the Xducer on the TM will skew the images on the screen somewhat...A lot of guys still mount the Xducer on the TM..you just have to turn the TM slowly and learn to interpret the images as you see them...
Give us more info on what/ where you think the SI would be most advantagious to you...I'm sure you'll get lots of help here...
