Could you give me any tips or advice regarding your program used with a Lowrance sonar log
1. Open the Lowrance Sonar Log Data  (*.SLG) file (menu File | Open)
2. Initially 3DField asks about the location of the SLG2TXT utility from the Lowrance Customer Service. You must have it available in your folders.
3. Also the program suggests to convert Mercator units to degrees and do negative depths (it is useful for 3D view).
4. Select Triangulation, Natural Neighbors or other gridding method in the toolbar.
5. Double-click on the Color Cells or Color Fill Contours tree item in the left window.
