[TowerTalk] Actual LP Performance vs Tribanders

[Jim Smith]

Hi Dave,

Maybe it's different now, but earlier GPS units were pretty inaccurate 
in the up and down direction.  For example, I was trying out my Garmin 
GPS II on the ferry boat between Vancouver and Vancouver Island.  It 
informed me at one point that I was 400 ft below sea level!  I 
considered complaining to the Captain about his poor seamanship skills 
but thought better of it. :-)
