Playing around with my friend's Etrex Legend HCx and reading the manual, I discovered something.
This applies only to the HCx series.The unit can write logs to both the internal memory and the SD card. In the internal memory, the 10,000-point limit applies and you are given an option whether or not to wrap (let the 10,001th track-point over-write point #1). However, if you choose in Track Setup to log tracks to the MicroSD card, by choosing the
Log Track to Data Card option, the 10,000 point limit does not apply. This is what the manual says:
This file is a continuous compilation of all track data for the indicated date. As long as this feature is enabled, a new file is recorded for each day you use the unit. Recording continues until the card is filled.
Using this option allows you to record a large number of track points (depending on the capacity of the microSD card). Track logs on the data card are .gpx GPS position data files and are not used by your unit.What a pity. Otherwise you can build big gpx files in MapSource and transfer to your microSD card. Anyway, it is good to know that you can have track logs bigger than 10,000 points.
Attached is one example of a log that has 10,534 points for a 3-hour hike.
