WAAS capability would increase your accuracy over a GPSr that doesn't have WAAS.&nbsp; Of course you have to be in an area where you are able to receive the additional WAAS signal.<br><br>An external antenna my also increase accuracy but results would vary greatly depending on the location and weather.&nbsp; the possible increased accuracy would probably not worth the added expense.&nbsp; I haven't priced out the antennas lately, but considering that the ammo can is usually somewhere within a 15-30 radius it's really not an expense I can justify.

They are all about the same.<br>
Each brand/unit will have it's quirks, but there really is very little
difference in accuracy.<br>
More money=more features, but probably not more accuracy.<br>

have a etrex legend that was about $100 and there were other units for
three to four times that amount.&nbsp; Does more expensive mean more
accurate?&nbsp; Or just more bells and whistles?

Thanks, Joe.&nbsp; Just hike.
