Update:

GPS unit. *The one I linked to in the original post has a pretty
consistant altitude error, of more than 200 feet. *The horizontal
position is consistantly quite good.

That altitude error is likely because the GPS is not using the WGS 84
ellipsoid. An issue with some GPS including those built into PDA/PNA/
cell phones etc.

That was my initial wag, but the manual states it is using the WGS 84
model. Whatever the reason for the error, that error may be the reason
the unit is soo cheap. I have asked a couple others in the club to
bring their Bluetooth GPS units out to the field for some comparison
testing (and maybe a BBQ!)
