I case anyone is about to go down the Mega Live rabbit hole I just did. I ordered a ice and boat setup for $3000. Humminbird has a $500 rebate on Helix 9 (and others) until the end of April. I ordered a Helix 9 DI G4N head only ($1100-500) and a Mega Live Ice Conversion Kit (shuttle-20ah battery-ice ducer-Mega Live transducer with pole-etc) for $1900 ($2500 from HB). A boat mount/rod with an Alumacraft bracket is under $400.
Not sure about site etiquette if I should say where since it’s not affiliated with IDO. PM me and I’ll tell you.
