Hi

Back when the Z3801 was new, some GPS's would let you pick a specific geoid
model to use for altitude. Apparently it's a receiver side choice of what
model to use.

I had a Tbolt and a Z3801 both fed from the same antenna and they indicated
26 meters differenence in altitude. The 3801 seemed closer to right. If
geoid error were the cause, it seems that both would indicate about the
same.
