Hello,
I have a jet boat with a sonar gps by Lowrance. I am using this to record my position and water depth. I then use insight Genesis software to generate contour maps of water depth. This allows me to determine the river channel which I drop way points in so I can follow these waypoints to stay in the channel. I joined this forum in hopes of getting information to questions such as
How to convert urs waypoint file to garmin
Bear in mind I have 1400 waypoints

How can I get more accurate gps location on gps
How to transfer the waypoints to maps like google maps

am I in the right forum?
