I use my mid-price Garmin GPS60 handheld GPS device to record waypoints for vegetation surveys and other field surveys, often under tree cover.
In asking 'should I replace my old unit', I should say that I don't really care about colour screens, backdrop display maps or any other enhancements. I just want good waypoints.
Would a newer mid-price handheld GPS do an appreciably better job of getting satellite fixes and getting better positional accuracy than my 7 year old unit?
Is the basic technology now better in some way, or is it much the same as it was 7 years ago?
