1) I have purchased a screen anti-glare overlay for the peng-pod which seems to make the screen readable in bright daylight - big plus
2) I have LibreCAD working on my PengPod - which willl be used as the interface program for the Surveyor. Big-plus
3) Currently writing Coordinate Geometry (COGO) routines for LibreCAD which will make the PengPod functional for Surveyors. This will take time but should open a sizable market to the PengPod which would be very competitively priced.
I will keep you all updated on progress - especially step 3.
Thanks for your time
