I have the Garmin vista HXC and love it. I use it out west and in Mo. with no problems. I can still receive a signal while it is in my pocket. On my last elk hunt 2 guys in camp had a Dakota and the 60csx. The dakota is way over priced and the touch screen could not be used while wearing gloves. I played with it around camp one day and I did not care for it.
The 60csx was a good unit, but it would loose the signal if placd in a pocket or pack, easy navigation with the 60 and it came with some nice options. Neither of the units would link as fast as the Vista HX-c.
And the Dakota did like to eat the batteries.
Just a few of my observations on both units.
