I used the Bushnell sport last year and did not care for it at all. Here are a few reasons why.

It has a 4X power monocular that leaves much to be desired in clarity. A big problem Ihad is on ocassion the unit would not range at all. Which I couldn't quite figure out why. It only ranged when it wanted to. I also had issues with where they have the battery located at. It is on the corner of the unit right on the edge where you grasp it when you pull it out of the carrying case. On a few ocassions the battery cover would pop off all together while removing the range finder for use.

So, just the other day I bought the Nikon ProStaff 440.

It has a bunch of great features that many other mid priced rangefinders do not have.

1/2 yard accuracy withmuch higher quality opticsthat has an 8X lense. It has a "continuous tracking feature that allows ranging of multiple or moving targets" This feature is rather cool You can choose between yards or meters for the display. It also has a focus on the monocular to go along with all the basic features such as automatic shut off etc etc.

The Nikon is just better than the sport in all aspects all the way down to something as simple as having a snap on the carrying case instead of velcro. You also never have to worry about the battery, it is 100% secure unlike the sport.
