Nice solid unit for the money, small screen is shortfall.
12 November 2013
Summary: Review wouldn't let me rate anything other than excellent on "display" so I left that one blank. This is a nice solid little unit but the display is too small for any real detail and at times the toggle can be a bit difficult to operate. It does have a lot of nice features and is fairly quick to initialize(find satellites). I'd recommend the touch screen 510 if you can afford it, but all in all, this one isn't bad for the money.
