For those of you using the Helix depthfinders do you use the LakeMaster or the LakeMaster Plus chip? And all I can find is the Version 5 chip for the LakeMaster chip so I assume that is the newest version?

I know there are some of you that download each lake or just use the base map preloaded onto your unit but I'm only referring to those that have purchased the LM chip. Thanks guys.
