curves and bends. It also displays the mini compass arrow, the
straight line trail to the POI, the distance from the POI and a
scale reading.

2. Trail Data Recording: This is the hidden power of the reTrace

Deluxe. Depending on the time interval settings (see Data
Log Period setting – in Settings section) the reTrace
can save from 14 hours to 50,000 hours of data! That’s not
a misprint. The design of the reTrace

benchmark setting method, press the SET key.

The Data Log setting tells the reTrace™ Deluxe how often to
record data. This is a powerful tool that collects info about your
