Swapping from Lowrance to Garmin and with all the transducer selection I am hoping to get a little help in making transducer selections. These will be on a 21' Skeeter 21I bass boat.

1042XSV Bow = ? Looking for Chirp, DV & SV would be nice.
PS21 ( Panoptix )

1042XSV Console= In Hull ( GT8HW-IH or GT15M-IH )
DV / SV ( Clueless on this, too many )

Any Feedback is appreciated.
