Whats everyones opinions of these? would it be benificial to update from a 12degree on my FL18? are they worth it($100 @ Cabelas). I'm mainly fishing less that 20 fow i figure it would help me out. its a little over a foot bigger radius @10ft than a 12 degree. the 9degree is 1.6 ft radius at 10ft i'm hoping that when i am fishing where there is alot of fish that the 9degree will let the vex read clearer than the wider transducers ???maybe??? i know they just came out for this season but i have some giftcards from last year to use, i just wanted some opinions on them before i buy one.
