I talked with Lakemaster a couple months ago and they said they were still making them but dont offer them on their website but he couldnt tell me how long they would continue making them!
So what I did was buy another new MN and LOW chipx. I now have MN 1 non HD, 2-HD and an insight chip. Then 2-HD LOW chips. I also run a Navionics and its got a few things that lakemaster doesnt but overall lakemaster has a lot more and I like the way it looks as well.
I think Lowrance has something up their sleeve Time will tell.
