- Sep 5, 2008I understand your dilemma. Hopefully you can find a product that will meet your needs. Let us know what you come up with in case others need the same capabilities.

like to use the Tracker2/Nuvi 350 combo to track balloons and chase teams,
then I'm sure I would not be happy with it. Balloons have an annoying way
of traveling outside any reasonable "maxrange" limit, even if you are
attempting to keep up with it in a car.
I already have a TH-D7ag and a GPSMAP76CS. The TH-D7ag, which has the "POS
LIMIT" feature (apparently equivalent to the Tracker2 "maxrange" feature),
and the GPSMAP76CS, which in this application (tracking moving targets on a
map) is the equal to the Nuvi 350. Well, to put it simply, they don't do
it for me.
Furthermore, I once read a review of the TH-D7ag, and the reviewer pointed
out that the "POS LIMIT" feature was of very limited value as it didn't (or
wasn't able to) delete the waypoints as they pass outside the range set by
the user. He wrote that you'll severely limit your ability to display APRS
beacons, but will still end up with your waypoint memory full, albeit at a
slightly slower rate, and a "circle of waypoints" will be left on your
display at the set "POS LIMIT" value.
In my own use of the function on my TH-D7ag, I've found that to be
absolutely true. Even more, if you are using the combo in a moving car,
your GPS leaves a trail of non-updated waypoints behind you as they pass
outside the "POS LIMIT" due to your own movement *even* for those waypoints
from stationary trackers along your way.
Also, the accumulation of unwanted waypoints, besides getting co-mingled
with (and difficult to delete from) your own non-APRS waypoints, add
additional clutter to the display and slow up the screen refresh.
If I have access to my laptop wherever I'm doing my tracking, I can do as
you suggest, backup (and restore) my own mostly non-APRS waypoints, but it
is yet another aggravation that I'd like to avoid, and doesn't address the
issue of display clutter and slowdown. BTW, there are other workarounds
such as using APRS Group Names or using a particular waypoint symbol for
waypoints from the TH-D7 (or Tracker2) so that a group "delete by symbol"
can quickly delete them, but these workarounds, like nearly all
workarounds, all have irritations and/or disadvantages of their own.Yeah, I suspected that. That is true of other Garmin GPS models as well,

even some handheld models. It is actually dependent on firmware version in
some models. The firmware version I'm using in my GPSMAP76CS (v4.00 I
think) updates existing waypoints with the new position, and doesn't leave
the trail, essentially "moving" the waypoint. I think there have been two
updates to the firmware beyond the version I'm using. According to a
poster in another forum, the newer versions cause a trail of the old
waypoints (with appended sequence numbers) left behind so I haven't
uploaded them. Fortunately for me, the other changes added to those newer
versions, I believe, only affect treatment of names in some foreign
languages, so I don't need them. Some newer models don't have earlier
firmware versions that handled updated waypoints in the way the Nuvi 350
does. Apparently Garmin's programmers had a change of philosophy with
regard to the method of handling duplicate waypoint names 2 or 3 years ago.
I think it was a mistake.Too expensive for my pocketbook since I already have a good mapping GPS and

two laptops. IIRC, the first two generations of the eeePC have a number of
limitations to reduce cost and size, so I'd be carful to confirm that it
has the hardware resources to run a useable installation of XASTIR before
plunking down the cash. For example, what source of mapping does XASTIR
use? Is it on a CD/DVD? If so, does the eeePC have a CD/DVD reader or
sufficient mass memory to hold a good collection of maps? If I remember
correctly, XASTIR runs natively under Linux, and I believe the first
versions of the eeePC also run Linux, so you'd probably be OK in that
regard, but I'd check it to be sure.
