Howdy fullas, great site my question is does anyone have a fcv585 with a1kw transom mount (TM 258) and if so what is the max depth you can see and fish. The hapuka/blue eye country down here is 180-280 fathom and we are struggling with the 600w ducer, mounting a through hull on my boat (233edencraft) will be difficult cause its got diesel inboard and access is tight. thanks
