Cabelas has the panoptix LVS32 system for 999 and the Garmin Echomap ultra 106SV for 1,000 for a total of 1,999 verses reglar price of both together being 3,300 for a savings of roughly 1,300. Is this a good price? Is it worth it? Is this a good unit or is there something better or comparable that is reasonably priced?
