It is my understanding that the WAAS satellites are best when you are nearer one coast or the other, not in the middle. It is my understanding that the WAAS satellites can be picked up here in the midwest, but you need to be standing out in the wide open to get any benefit.
I think that most geocachers turn the WAAS feature off, because some believe (correctly or incorrectly, I don’t know) that it actually decreases your accuracy when you are in the woods.
My information is old and coming from the deep dark recesses of my brain. Maybe somebody else has some more good information on it.
Here’s a link to Garmin’s site that has some additional info which pretty much echoes Buy_The_Tie’s post. It also has pictures, and how can you go wrong with picture? 🙂
Thank you for the feed back, and the link to Garmins web site. I had an older etrex that I used for hunting and kayaking, and I had never noticed the drifting before. I was concerned that my new E-trex Ventura might have been defective. I am still learning all the bells and whistles that this unit has over my older unit.
I think that WAAS DOES help. A local cacher had it disabled on her Map76csx and her posted coords were always about 45′ off, but had no problems dnding here caches last weekend.
