Could be... Brochure doesn't say much,

I find the claim of range accuracy at 0.2 nm *on average* to be highly
suspect. I doubt very seriously they can hit that number. But I don't
find that to be a show stopper. The other numbers they give should be
doable, although bearing quadrant will have some significant error in
it.

Wonder how big a deal the antenna installation is. They don't say
anything about that, yet it will need at least one and preferably two
antennas installed outside. STC???
