Hunting the elusive whitetail can be enough of a challenge in itself that I want to have products in my arsenal to help give me an extra edge. When the moment of truth finally happens I want to be confident in myself and confident in my equipment. There is nothing worse then putting a lot of money into your hunting equipment and hours in the woods and field only to have something malfunction. Therefore, I try to buy quality products from companies with reputations for delivering the best items in their respective fields.


If there is one area that is responsible for the most misses, I would say it is misjudging yardage. Depending on the distance, you can usually get away with small miscues in shooting form, but nothing sends your arrow (or bullet) sailing over the animals back or falling short quicker then overestimating or underestimating the distance to the target you are shooting at. When it came to choosing a new rangefinder I knew I wanted the best.

I recently got the Leupold RX-850i TBR Compact Digital Rangefinder. The first thing I noticed was the size of the rangefinder. We all have way to many things that we haul into the woods with us for each hunt. Smaller and lighter is better. This is where the Leupold really sets itself above the rest. Some other key features are: 60% Light Transmission which will come in handy while having to range in low light conditions which hunters are accustomed too. The range finder ranges from 6-850 yards so it is perfect for ranging those close archery shots and also suitable for hunters taking long range rifle shots. True Ballistic Range is another key component. Leupold RX Series rangefinders are the only rangefinders to provide accurate aiming information matched to the performance of your rifle. True Ballistic Range is calculated using a propriety state-of-the-art ballistics algorithm in combination with the following variables: shooting angle, line-of-sight range, and rifle cartridge ballistics. TBR provides hunters with the equivalent horizontal range for precise shooting with any change in elevation. TBR for rifles is effective to 800 yards, while TBR for bows is effective to 125 yards.

This rangefinder also boasts Leupolds DNA (Digitally eNhanced Accuracy). This makes significant improvements in what matters most: distance measurement accuracy and displayed range precision. This produces .5 yard accuracy and the displayed range precision using 1/10th yard increments out to 125 yards.

For those who have a hard time judging the size of trophy racks then you will be impressed with the Trophy Scale which allows you to instantly judge the with (or height) of your target. All you do is pre-set the scale to represent your desired width and you get a visual indicator for you preferred width at any practical distance.

The rangefinder is waterproof so there is no need to worry about it failing if you are hunting in inclement weather. It also features fully multicoated lenses and a lanyard. Included in the box is also a cordura holster that can be placed in a pack, pocket or clipped to a belt loop.

Other Specification:

Magnification-6x

Field of view (ft @ 1000yd)-310

Angular Field of view (degrees)-6.0

Weight-7.0oz

Objective Aperture-23.0mm

Twilight Factor-11.5

Exit Pupil-3.6mm

Eye Relief-14.0mm

Dimensions (LxHxW)-4.2"x3.0"x1.6"

If you're in the market for a new rangefinder, do yourself a favor and check out the Leupold website. You will be glad you did.

I have limited experience with rangefinders. What I do know is a common shortfall is the limited capabilities when ranging a deer, trees, etc.

For example, a rangefinder may advertise capabilities to 1000 yards, but that only works on a reflective surface size like a car. To range a deer, coyote, or smaller nonreflective target, the realistic maximum range capability drops to 500-600 yards.

How does this model respond with such a situation?

The best range finders on the market today are the Sig Kilo's. I've had several range finders over the years,and unless you spent $500+ you were buying junk that would only range game animals out to a couple hundred yards.

That Leupold 850i might range a deer sized animal out to maybe 350-400 yards,that's it.

The Sig Kilo 2000 that I have will range reflective targets out to 3400 yards. I know it will easily do 2775 because I've ranged it that far. Deer sized animals can be ranged out to around a 1000 yards,I've ranged cows at the ranch at over 1100 yards.

It does cost more than your Leupold 850i,but it's worth every penny. I'll take the Sig over any of the competition any day of the week.

Comments better than the review

Kudos to the comments, I think they are better than the review.

Ranging with typical equipment in typical brush situations is not very reliable beyond 400 yards.

I suggest addressing the ranging issue either by strategic choice of your zero range for up to 400 yards and by using a 1st focal plane mil-dot optic for longer ranges.

If I zero my 7mm Rem Mag 4 inches high at 100 yards it will be zero at 300 yards and 12 inches low at 400 yards. So aim 1 mil-dot low at close range and 1 mil-dot high at long (400 yd) range. (1 mil-dot = 3.44 MOA)

After 400 yards I suggest MOA adjustment based on ranging via the Optic's 1st focal plane / Mil-dot reticle combo. You won't have to worry about brush giving you false readings and you can set up your dope chart to convert right from reticle mil-dots to turret MOA adjustment. The range finder cannot do that.

There is an example of a FFP Balistic Calculator chart at www.OptiCo.us

I would never waste money or shooting setup time on a range finder.
