looking to upgrade this year from the old 1199hd si combo to a gen3 or 4 helix mega unit 8or9. can't decide if i want to go si or di, in the spring we fish 10 to 15 ft water, later up to50ft. was wondering what would be your preference for the upgrade? does the si really show the detail in deeper water ,all the pics i've came across seem to be from shallower water . or what would be your choice.
