OP didn't mention DSI..I called it a combo because of both gps and sonar along with the DSI which is regularly $599.99. I paid cabelas $299.99 for the Elite5 DSI after I returned the $350 bass pro black friday Elite-5 DSI sale last year.The OP is referring to a DSI unit, not a standard elite 5.
$249 is not the combo. There is no GPS chart on that unit.So general consensus is that this is a quality unit and a great deal at 250?
