What kind of GPS is this?

The Trimble Geo Explorer CS.
http://www.anthroyeti.com/gpsmanual/chapter05.htm I have a line of a few of these but don't know much about them. It seems like serious over-kill for geocaching but if I can get the lot and sell all but one or two....

I'd be interested in one depending on the price.

They are high accuracy models used for data collection in surveying, bioloigical and environmental deliniation, engineering, trail and road planning.

You use these when you need to gather more than just a track, when you want to be able to see property lines and manhole covers, and roads, and have specific data about each one of those features all displayed in the plam of your hand.

These are used for professional geocachers, where the search is the job and cache is a paycheck.

let me know if you pick these up.

Same here, let me know if you need to sell off a few.

this is relevant to my interests.

As stated before, Trimble makes GPS for surveying and other high-accuracy jobs. They are accurate to 2 cm, which is roughly .8 inch. You can overlay GIS data and show property lines on satellite photos. Using one of these units for geocaching is like using a tactical nuke to free rusty bolts.

These units are $$$ so if you get them at a good price you can turn them. I'd sell 'em all and pick up a consumer handheld which will be more then fine.

Every Garmin GPS uses the same GPS chip so they're all equally accurate. It's the gravy that costs extra. For $150, you can own a Garmin eTrex Venture with a color screen (uses less power than the b&w) and download cache coordinates from the web without the $35 proprietary cable their cheapest GPS (the eTrex H) requires.

You don't even need mapping software. Learn to use the GPS with a $6 piece of plastic called a UTM square and a topo map (which is basically how the military uses it). I can teach you in ten minutes. You can teach the rest of the world after 20 minutes.

I'd love to have a Trimble for ArcPad so I could draw stuff back at the office and then flag a cooridor out in the field 30 minutes later.

To do that with a Garmin is ok as long as I don't need to show multiple layers. If I do, then its a very long complicated process to convert shapefiles into and map documents into something the Garmin can understand.

Funny how I posted this queston on this board, a forum dedicated to cheap-a$$ people who like cars as well as a geocaching form. 7 responses here with some very good, detailed info and one there. The one post there said "it'd be a PITA without a native way to handle .gpx files." with didn't really tell ME anything. Thanks guys.
I did an eBay search and only found two chargers for sale. What if I got a few for $100 each, could I make a buck?

If you sold one to me for $125, yes you could make 25 bucks.

If I remember correctly the are fairly old now. I'd like to try to find some specs on them. They run windows mobile, so more power the better.

Have a Timble ProXH for GIS use at work. It works very simular to the Geo-Explorer series of units. Most of these units require separate software, such as TerraSync or ArcPad/GPS Correct to operate properly. The instructional information in the link looks like TerraSync.

It looks like these units are several generations old, and will likely not be supported by Trimble. That why they may be so cheap.

The unit we use was a "on sale" demo unit that was about $13k. We since have had to update the data collector once and the software each time there is a new version of ArcGIS in use to the cost of several thousand dollars. This is to get sub-foot accuracy with post processing.

These are not consumer devices and can sometimes be very frustrating to use.

If it was me, I would get a consumer unit, much easer to use. = Fun to use.

Thanks for the info guys.
I have a e-Trex legend or vista and loved it, till it went and got broke-ded. I have a Nuvi now for on-road nav. It rather sucks.

Garmin is working on this as they've been outflanked in this respect. Both DeLorme and Magellan have platforms with GIS capabilities. Garmin's still pitching their ability to use sat photos. In my realm, (backpacking off-trail), I want the Garmin's throw-it-off-a-cliff-and-go-get-it durability rather than layering capabilities.

Also, the newest eTrex line (10, 20, 30) has a new faster processor yet shows much-improved battery life (25 hrs).

Those Trimbles are old so I think the OP needs to get them for less than $100 per. More like $50.
