Even in handheld GPS GT-31 has various features.

 Below the set speed and stop the logging. As an example [2] to not record log data set drops below 2 Km below when you can.


 Features sound the alert exceeds the configured rate. As an example [60 KMH] into ring alert and set more than 60 km per hour and will warn you.


 It is possible to save and select the item you want to record from the middle of the GGA, GLL, GSA, GSV, RMC, VTG, ZDA, SBN NMEA-0183 sentence * 1.

It is also the Japan language display. (Available in English while also some Japan translation is hard for you)
When you purchase [Japan language show hope: take advantage because ships we hope you'll choose Japan to display the settings.
