Mike, 

You mention the Holux M-2000. Did you mean the M-1000 or is this is a
revision of the M-1000?

Thanks, 

Kevin

Hi Mike,

This is indeed interesting.  One question, when outside, did you test in a
stationery position or were you moving?  I am also interested in something
else if you were moving.  This morning I was monitoring my speed.  I was out
on the levy, and was moving steadily in a quite open area along the river.
I was noticing my heading varying plus or minus about 10 degrees, and my
speed jumping all over the place from 1 mph to around 6.  The truth was
likely around 4.  This was the royaltech 2110.  The accuracy I was seeing
most of the time around 29 feet.  In fairness I had just come from my run,
and I was carrying the receiver in the pocket of my running shorts.  This
means that it was swinging pretty freely which may impact all of the above.
