I think he is talking about EMC( Electronics Marine Concepts ).I used the guys on Rt. 9 over by Walmart in RioGrande. They were fast and reasonable. They even replaced the antenna and were still the cheapest I found in the C M W W area.
Just curious here. why in the hell would they design these things so they have to be changed out by a dealer? cannot understand this, I have two scuba computers that I can change the battery out very easily and I take this thing down up to 140 feet and it does not leak.
