BHelman,

people should really read for themselves. Here are some quotes I saw:

You said "inconsistent explanations coming from Surecheck with
regard to the issue."

from AvCon:
"As noted, this allows the SureCheck to make relative altitude determinations
when the host aircraft Mode-C isn’t available, which appears to be the case
about 20 percent of the time for reasons that aren’t clear. "

and
" For some reason, this doesn’t seem to be a problem with the signal
received from other aircraft."


The only edge they even mention for the Monroy is price and display,
but not functionality. Performance wise they clearly state the Monroy
did not perform as well, but is cheaper too.

Well, this quote at the end clearly says the opposite:

"We give a razor-thin edge to the Monroy ATD-300. It’s $400 cheaper than the
SureCheck, has a lower profile on the panel and a simpler, easier-to-read
display. Our impression is that the ATD-300 more often saw traffic that
the SureCheck missed but, to be fair, the performance of both units is
strongly influenced by antenna position."

Only then does it go on to say what you quoted:

Their LAST and ENDING consclusion states clearly. And, yes this is
word for word.

"If that capability is important to
you or you can't run on ship's
power alone,
