My Galaxy Tab 2 has a micro SD slot and takes a USB host cord. This is a short $5 cord that plugs into the main port. Some GPSrs plug in directly, and others need a powered USB hub inserted between. The file management app that comes with the tablet works well. So, you can get your PQ by email into your tablet and transfer it to your GPSr. This tablet also has a very good GPS receiver (GPS and Glonass)and will run the Android geocache apps.

Since your Garmin keeps track and waypoint data in GPX file format, just drag them over to Google Earth.

I set all my GPSRs to True North and will only change it if a multi-cache specifies using magnetic north in a bearing or projection. My handheld compasses have declination adjustments so I read true north on them also. Makes is easy to keep maps and everything on true north.

SGT, what you are describing are segments in a track file. Many GPSrs create a new segment when you turn off/on. An essential Track utility is the program: G7toWin You can drag one or more track file into it and see the segments and track points in a spreadsheet format. You can easily edit, delete, add, or combine the segments or track points, and save as a new GPX file. Each line(track point) will show fields such as elevation, time (in UTC), distance between points. Right mouse click to bring up edit choices.

Many posting here do not know how good is the GPS receiver in the new Samsungs. My son and father have the S3 phone, and I have the Galaxy Tab which appears to have the same GPS. I just turned it on in my house, and in 5 seconds, I get a position with 18 satellites (GPS and Glonass.) Very sensitive and fast, and appears to be accurate. You do not need a cell signal for position or for maps if you cache them, or if you get a map app. The GPS in these Samsungs is much better than the one in my Droid X, and more sensitive than most GPSr units. I have not tested the Samsung at a Super-Accurate benchmark, but it compares to my Garmin 20. So, Dizz has a very good geocache finding tool.

Yes, this is a good idea. I did it with my 20 when I got it. For all my GPRs, I also stick a Brother label on the back and inside the battery area. Then make a text file named: ownerinfo.txt and put it in the internal memory.

I am assuming that the 10 works like the etrex 20. You can project from any waypoint. If you want to project from your location, first save it as a waypoint. Start with the Waypoint Manager and then from the list , choose one, click on the details, push Menu button, chose Project Waypoint, and enter the Distance and direction, save it then go to it.

I have a Galaxy Tab 2, 7". It has a very sensitive GPS that includes Glonass. For $6 I got a USB Host cord. I have connected and moved files from my GPSr (Etrex 20.) It also has a micro SD card slot that you can store and transfer files to. It also has a front and rear camera, and IR tansmiter for controlling your TV. WIFI only. I believe the larger Tab has all the same features.

GPS Apps that are on my Droid devices include one that is good for the original question: "GPS Averaging" which will give you the coordinates of your location, averaged for as long as you want. I would go back at another time or day and do it again. Other Apps that I use regularly: GPS Test, GPS Essentials, GPS Status, and My Tracks.

I just now picked up my son's S3 and tested it. It has a very sensitive GPS, quick to fix. It receives and uses glonass, and looks accurate with no bouncing. I have also been testing my Tab 2 which seems to have a similar GPS receiver. Inside my house it often receives and uses 16 to 18 satellites.

Yes, the Nuvi records the tract whether you have it displayed or not. To delete the tracks, all you need is a standard mini USB cord. So, if you are selling or giving away your Nuvi, or want to erase where you have been, you need to delete the file: \Garmin\GPX\Current.gpx You also need to go into \Garmin\GPX\Archive\xxx.gpx and delete all of the archive files. These are track files that are created when the current.gpx gets to a certain size. There will be a maximum of 20 of these archive files, the oldest dropping off when a new one is created. The current.gpx file can get to about 2MB (about 400 to 500 miles of urban and freeway driving), and each archive file about 1MB (about 200 miles of the same), so the tracks do not take much room. It is a privacy issue, for yourself, and can let you see where someone else drove your car (date,time, and location.)

Does it have a USB out port? If you can plug a USB flash drive in, you can plug in a modern GPSr. Does it have "ICS", Android 4? If so, you can try it. - Save a GPX to the tablet from the web site (or do a Pocket Query and save that). - Plug the GPSr into the USB port. Be sure it's recognized as a drive. - Copy the GPX to the GPSr, into the appropriate directory. If you did a Pocket Query, it needs to be Unzipped. The free version of Astro file manager automatically does that, probably the other ones do, too. You will need a file manager to move any files. As robertlipe mentioned, you can't directly "Send To GPS" as you would on a PC. That requires plugins, drivers, and deep magic that the Android doesn't do. For this to work, you need a tablet with a host USB port or cord. You also need a GPSr that can take multiple GPX files. I have a Samsung Galaxy Tab 2,7 inch, and I got a $6 USB host cable. It's OS is Ice Cream Sandwich. I connected my eTrex 20 and it recognized it as a USB drive. Then GPX files of PQs can be transfered. It will not do a send-to-GPS, but should be able to create a GPX file for the individual cache instead and move this file. This Galaxy Tab has a very quick and sensitive GPS chip. In my house, it gets a position fix in seconds, and receives the Glonass satellites, so that it is using often 17 satellites for the fix.

the comments by Grasscatcher are right on. It is just what I would do. I would not assume the that "official" track is correct. It might have additional ground covered. I addition to Google Earth for comparing the GPX log files, I would use some utilities such as the online: GPSVisualizer. And utilities/apps such as "Analyze Track" and "G7toWin"

Want maps on your Magellan GC? above is the tread that describes the firmware change. The GPSr works great, but you will not have a working map, just a very basic base map. I have not taken the time to find and install maps on it. This may take some work, and cost. I do not recommend the conversion for most. I did it because I have several other functioning GPSrs, and I could experiment. For new GPSr users, I recommend buying the 110 or GC or 310 and use Vantage Point. In a couple of minutes you will have your PQ of caches loaded and out the door cache finding.

I have the GC, and the 110, and did the firmware conversion of the GC to a 310. Of the three get the 310. If you want lower price, get the 110 over the GC. You are limited to 500 caches on the 110, but the other features, like track logging are worth it to me.

Check the battery type in set up.

When you are on the map screen, press the menu button and you get options. The main one to decide here is to show the compass over the map or not. You also have the ability to show compass on the Dashboard screen choices. Show compass. In this Map screen option menu, there is another choice called "Map Options" Here are some suggestions: map view: 2D Orientation: Track up map Fields: 2 Fields (You can choose these fields in the main menu) Quick info: Distance/Bearing Degrees Post-Dest line: On Orig-Dest line: Off Show Tracks: On Map Detail: Medium Topo Lines: On Shaded Relief: Off geocaches: All, Icons and Name Waypoints: Icons only POI: off Current Location Icon: Smart Arrow Auto Zoom: On map Draw Mode: Exclusive Try these as a start and you can always change them later.

Consider an Explorist 110 that I saw on sale last week for $100. It has maps installed and you can use the free Vantage point program from Magellan. Become a premium member and this program will find your PQs and load up to 500 of them. it uses standard gpx file format, and keeps good tracks for use in other programs like google earth.

OK, we know that use will be camping and areas with no cell phone coverage, and that price is not an issue. So, we know that topo maps will be helpful. the other big question is how much tech experience the owner has, such as creating and loading maps to the GPSr. If you want a GPSr that you can just put in batteries and run out the door, then the Magellan 310 with topo maps installed, or the Magellan 510 that has the maps and larger touch screen. The Delorme PN60 is also excellent, and comes with topo and computer maps. As for Garmins, go for one with the T in the model name such as Montana 650t. The Garmin eTrex 20 or 30 mentioned are small, light, and have long battery life, and you can find and load free topo maps with minimal effort. As for GPS compass, many of us do not use it because: Have to calibrate, and then always worry that it is out of calibration, and uses battery life. I always carry a compass that is more accurate and better to site my bearing which is shown on the GOTO "compass" page.

If you have a windows pc get the Vantage point program from Magellan. Click on the Geocache icon and find your PQ. Then sync pc to gps. This method will get you cache images on your gps.

If you are a premium member, you can run a Pocket Query. Then get the free Magellan software: Vantage Point. It will connect and show you your PQs, choose one or more, and then export to .gs file format. If you are not a premium member,try to get individual gpx files and import them into Vantage Point.

will allow caching of their maps, so no connection needed.

The Lenovo Ideapad A 1, 7 inch,$170, is supposed to have a good GPS receiver. Get a geocaching App, and some GPS Apps like "GPS Essentials", and get your PQs sent to an accessible email. Soon, google maps

The etrex 20 does a decent job. It saves tracks in gpx format, and lets you archive unlimited number of tracks. I am using one for track logging several days a week. Also consider the Explorist 110 and 310. I own these and also use them for logging. Accurate and use gpx file format. I have a Delorme 30 which does a good job, but battery life is low. I understand the 60 has much improved battery life.

GPS Essentials. It does it all.
