Lap Counter operation
The lap counter, if used, can count either up or down. Initially, before any laps have started, it
displays “-”. If set for counting up, then at the beginning of the first lap it will display “1”, and “1”
will continue to be displayed during the hold time. It will keep counting up, no matter what the
setting for “number of laps”.
If set for counting down (say the number of laps is 5), then it will display "5" during the first lap
and its hold time, and will decrease by one each lap. When that number of laps is complete, the
lap display will revert to “-“.
Tracks
The GPX automatically determines if you race at a new track that it has not yet encountered, or if
you are at a track that you have been to before. It does this by monitoring the size and shape of
the track’s “loop” and either matching it to a track that is stored in its memory, or else creating a
new track.
Example: You go to a new track for the first time, and start racing. Once you have completed a
“loop”, the GPX determines that you are at a new track. It records your session, and when it is
done, it will default the track name to something like “NEW TRACK 1”, and you may then change
the name to the track’s actual name.
Start/Finish Line
Each track layout in the GPX has a start/finish line associated with it. (In actuality, it is a start/
finish “point”). The start-finish line is that point on the track at which a line across the track goes
through that point.
The simplest way to get a start/finish line at a new track is to do nothing. Race around the track,
and the GPX will find the “loop” point and use it for the start/finish line.
There are two modes for having the GPX determine the start/finish line (menu item
Track
detection method
).
First loop
(the default) is just that – the GPX determines the first time a loop
is “closed” and makes that point the start/finish line
. Longest straight
requires an additional 1-2
loops around the track, and in this case the GPX sets the start/finish line about one-third of the
way down the “longest straightaway”. (The straightaway that the GPX calculates allows for some
slight variation from a straight line]
The other way to set a start/finish at a new track is to walk over to near where you want the start/
