Hi Plainview,
The laser box or reticle is small for a reason. It helps you be more certain of what it is that you are actually ranging. The laser beam is 2.5m wide by .5 m tall at 1000m. You need both a small beam and a small reticle to be certain of what it is you are ranging. Just like shooting a rifle (but not as bad) it is going to be tough to hold steady on objects at long distances.
As to your Geovids not ranging anything past 600 yards, if that is the case, there is definitely a problem. Send them back to Leica and ask them to check collimation of the laser. Email me if you need any help.
