Query: Nice

So far, I've been very happy with this unit. It looks and feels well-made. The LCD is extremely sharp. Navigating the software is intuitive. There are endless ways to customize the unit to your tastes. I almost always have better than 20 foot accuracy. Battery life seems reasonable.My only complaint is the backlight. It's quite dim, and so is not really helpful unless you're in pretty dark conditions.
