Today I trolled around a local lake and set about 25 waypoints.
Some of them displayed as a colored circle with the WP### label beside them.
Others were displayed as a smaller black circle with a white dot in the middle but no label beside them.
This was with a Helix 9 G3 and the waypoints were created with the "GoTo" button on the front panel.
Why were two different type waypoints created?
