The GPS receiver has no way of knowing what the error is so it only estimates it. However, I frequently see my GPS showing an EPE of less that 15m. Note that 15m is the error that you can expect without SA. EPE is one thing on the GPS I choose to ignore unless it's significantly greater than 15m.

Piloting is what you do with chart, compass and land references. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
