Sounds like one of those "You got to be smarter than the thing your working with" deals.
I been on this board for alot longer than the 620 has been out and never read anything but great reviews on it.
That coupled with how much I love my old 582 is why I recommended it.
If you want to fire it up in the driveway, I'll come over and give you a hand setting it up as the controls are very similiar to my 582.
If not I can't do it until I get back from up north in a couple weeks and the back is healed up a bit.
I know on my 582 you can change all the digital information fields to display the information you want to see as well as the size of those fields and text. I used to always change it back and forth to display est time to arrival when I fished tournaments.
Until then don't get your pantys all in a bunch.
