OK, understand.

OK on that.  We all have our methods and that can vary
depending on where we are DFing.  But, my question 
was about the particular type/style/model of COMPASS 
that you and others use/might use for their own DF'ing
antenna.  

Some may not use a compass at all, and some may
choose anything in between.  Some may use a "boat compass"
and others something else.  

So, guys, what style/type/model works best for YOU if you 
use a compass?

Charlie, N0TT
