To familiarize yourself with this
Grid Square app, here are some things to try.
Only GPS location services may be required for the following 1-12:
1) Change Screen Orientation (rotate device or hold Options button to switch Portrait/Landscape).
Note: Sensor orientation is used when app is launched. Hold the Options button to switch and lock Portrait/Landscape for that session. Sensor orientation is restored when the app is restarted.
2) Set GPS Scan Rate (hold Get Location button).
Note: the GPS Scan Rate is the minimum amount of time the GPS locator will wait to request information and can fire at any time after the Scan Rate interval.
3) Get your current Location and Grid Square (tap Get Location button).
Note: prior manual GPS activation required.
4) Have the Grid Square value read to you in phonetics (tap the Grid Square value).
5) Toggle Altitude between meters and feet (tap the Altitude value).
7) Show/hide Azimuth reading (tap the Azimuth reading).
Note: If your device does not have an Orientation Sensor, then this will read "Azimuth n/a" and will not respond).
8) Switch among D.D, D:DM and D:M:S (tap the Latitude/Longitude values).
9) Enter custom Latitude and Longitude (hold the Latitude/Longitude values to enable numpad).
10) Change the numpad font size (hold Latitude/Longitude to enable numpad, then hold numeral "1" key as many times as desired).
11) Use Extended/Super Extended squares (Options > check Ext. Square/Super Ext.).
