I was pulling out of the parking lot of Jay's Sporting Good's "Jay's is like Cabela's" and a truck was pulling in with Lowrance written all over it. So, I did a quick u-turn and stopped and ask a few questions about the new iway600. First, they will be sending them out starting next week. They have already quit making the iway500 and the iway 600 will replace it. So, don't think you will want to buy a iway 500. He assured me that they spent a lot of time getting the quality control a lot better with the iway600. He also said he has seen the 500 and 600 side-by-side working and they are day and night different is the quality of screen display. The 600 uses J-peg and has some features not even listed on the description page of Lawrance. I forgot to ask them if it will have a card slot. He was really excited talking about the new unit. We will see in a couple weeks after it gets in some users hands.
