Re: Hank held GP units...elevation accuracy?

I have a hand held Etrex 20 Garmin I use for measuring odd shaped fields.  I works good for that.  Today I was checking it for elevation and it was jumping up and down 2 to 3 feet when I was standing still. So, I would not recommend this model for your tile job.  There just may be other models out there that will work but for sure your tile has to work.
