Waas (wide area augmentation system) is a form of differential correction. It is satellite based and decoded by the gps reciever as opposed to the radio based diff corrections. Waas is generally accurate to around 2-3 meters where as the radio based signals may be a little more accurate depending... Id say go waas as you only need the waas ready gps reciever and the corrections are recieved by your gps antenna, as opposed to the radio antenna and decoder, plus gps reciever of the radio based system. Hope that helps... Chris

I can just add that I have both on my boat and there is virtually no difference. I am generally using it to find some pretty small sites so accuracy is important. (by small I mean a single 5 gallon bucket on the bottom in 100ft of water maybe 10 miles off the coast, etc). I hope that helps
