Geo-Scouter

I have a Sportrak Map and use both programs. You have to use Mapsend topo to download to your GPSr if it is capable of receiving downloads. I do not know if the yellow one is or not. NG Topo! has more detailed topographic information but can not download to GPSr. It can read route and waypoint info from your GPSr and display the information on it's maps. I'm glad I have both and would recommend both.
