I just enter the Rx coordinates into my hand held Garmin 12 and it takes me right to it. I chose the hand held GPS option because you may not always have cell phone or internet reception like in Argonia!
Just make sure you practice with your chosen GPS and set it up to select the appropriate coordinates. Decimal Degrees? Degrees, decimal minutes? Degrees minutes, seconds? I know it's elementary but I've witnessed more than once, someone inputting the wrong parameters. Practice before a launch.
That was one advantage with APRS trackers. The prospect of having the coordinates automatically entered into a compatible handheld mapping GPS via an interface cable. Nice, but I paid a royally high price a couple of years ago for a compatible radio and Garmin 60Cs to do it. I believe the EggFinder trumps this by price, even if it involves manual input of coordinates.
Now for those with Android phones, GPS Rocket Locator will shoot a line to your rocket in real time. If it doesn't have access to online maps, it will still shoot a line to the rocket one can follow. With a B/T connection, one can have a fully automatic real time tracking station they can carry out to recovery. Maps out on the lakebeds probably aren't a help but for those in the central part of the nation, it can help to know which road the rocket is closest.
For flyers who are hams and already are doing APRS tracking, one can plug the EF receiver into a laptop as the "station" GPS and have their attached TNC crossband repeat their EggFinder position via an APRS packet. Can send out a packet every 2.5 to 3 seconds that will also have the GPS altitude in there that
the EF sends back. The MapSphere program can't read the altitude but Xastir, UIView and YAAC can do so and retransmit as APRS. Example in this message:

Folks who have APRS radios, (D7A(g), VX8GR, D72A FT1DR) can use them to read out position and altitude coming from the Eggfinders by having the position retransmitted by the tracking program to APRS on their laptop base station.
Just a neat little caveat one can apply to the EggFinder system to squeeze a little more info out of the returned packets.
Yeah, the perfectly capable bare minimum works with the EF LCD and a handheld mapping GPS for manual input.
Have an Android device already that has a GPS in it? Add a cheap B/T module to the EF LCD receiver and one can track automatically in
realtime on the Android device. Kurt
