DON'T PURCHASE A LOWRANCE!! The customer service at Lowrance is the biggest joke in the industry. You absolutely cannot purchase individual parts from Lowrance without giving a kidney. The folks at Hummingbird are hands down sooooooo much nicer to deal with. I recently purchased my dad a new Hummingbird with the built in GPS like the M68, and strongly believe it is a superior machine. Several Hummingbird machines also can be changed between two different frequencies where the lower end Lowrance's cannot. This is nice when fishing in close quarters.
I purchase a new HD5 Lowrance last year, and called Lowrance to purchase the bag from them, and they would not sell just the bag by itself. They wanted $150 to purchase a kit when all I needed was the bag. I called Hummingbird, and purchased a bag from them, and can truly say that it is much better than the Lowrance bag. I actually fits the Lowrance HD5 better than Lowrance's own bag. It is a much better thought out bag.
Yesterday my brothers M67's charger started smoking when he plugged it into the wall, and he also called Lowrance this morning to purchase a new charge cord, and they would not sell him a new charger either. They told him that he would have to buy the whole kit with bag, and that now it is running $180. He said that Hummingbird had it with a battery for $40, and the Lowrance guy told him that he better buy it from Hummingbird. This is the saddest customer service department I have ever encountered.
Also, you will be on hold with Lowrance most of the time for about a half hour before you get someone on the phone. Another reason to look at is that Lowrance sends all units to China when a repair is needed I have been told by a dealer while Hummingbird does all their repairs in Louisiana. Lowrance's turnaround is supposedly up to 8 weeks where Hummingbird guarantees your unit back in less than 2.
I sure wish I would have went with the Hummingbird after knowing all that I have found out about Lowrance. I hope this may help you in your decisions. I had to learn the hard way.
