with the introduction of the new humminbird 360 technology ,will this be the beginning of the end for si/di ? with humminbirds 360 degrees of coverage area compared to the old coverage area of only 6 degrees front to back for both lowrance and humminbird si/di units. doesnt this mean we are entering a new era of technology and leaving one behind? with this new technology the boat doesnt have to be moving to operate or for that matter doesnt even have to be moving to mark waypoints off the live updating 360 screen
