MilGPS

I work in the Kuwaiti desert where I may have to navigate at night over long distances. Anybody that has ever had to navigate in the desert knows what a challenge it can be, especially at night. This app is by far the best land nav tool out there. When properly setup and calibrated, the accuracy is on par with a dedicated GPS. I have verified it against several GPSs and it has always been within 10-15 meters of the intended point versus the GPS. I highly recommended it. However, as
a word of caution, to ensure the best accuracy take the time and select the correct settings. If you are using MilGPS in the MGRS mode as I do, and you are using it in conjunction with a military map, be sure to select magnetic north versus the defaulted true north setting.
