Central To Everything and Close to Nothing | Some Etrex models are WAAS enabled but don't fool yourself thinking it is as accurate as an ag guidance system using WAAS, ie. sub-meter. I have an Etrex Vista C and with the WAAS turned on the accuracy will improve to 2-3 meters vs. 6-7 without it. Since the new WAAS birds went up, I have been able to get a differential correction but up until then I could not in this part of the world. I found that with the WAAS enabled but not recieving any signal, the accuracy was worse than if it was shut off. Just my two cents. |
