NMEALog is a small, intelligent logger that captures NMEA data for position and depth and stores it in a format suitable for amending existing charts.

NMEALog accepts data from up to two instruments natively, or several via a mux and logs data based on settable criteria, such as delta position, delta depth, delta time. Data is logged onto an SD-card and one card can hold several months worth of data.
