Helix ice conversion kit works with CHIRP models 7,8,9,and 10.Take your unit and use it as a flasher,down imaging or split screen.You can use your lakemaster chip to locate drop offs and contours.Use your saved waypoints.It comes with a transducer,power switch,multiple 1/4"-20 mounting options,two rod holders and a battery cover.This kit is brand new and never used.I bought it with the intent of using it.Then Humminbird came out with Mega live 2 that dropped the price of Mega live 1 to an unbelievable price.I paid $450 for this kit yours for $250 or best offer,I take the loss.
