The Kestrel Sportsman Ballistics Weather Meter was made for the hunter or amateur long-range shooter with an in mind.  It contains same environmental data as all the 4500 models, and the option to open up in a Ballistic mode with a G1/G7 ballistics calculator to instantly provide accurate targeting DOPE for shots within the Supersonic range of the bullet or approximately 800 yards. It stores up to 16 personalized gun/bullet combinations. The complete weather meter with built-in recording also allows you to log the environmental conditions of your best hunts and identify animal behavior patterns using your specific captured data.

You have the optics, ammunition, and gun - this meter helps take the guesswork out of your shot as well as aid you in practice of reading the mirage and recognizing environmental conditions that affect your shot.

G1 - G7 Ballistics Coefficients
Muzzle Velocity Calibration
Applied Ballistics Gun Loader Software
Built-in crosswind calculator and target range estimator
All in one environmental meter and ballistic solver
Rugged, Waterproof, Compact
High precision, local environmental measurements for more accurate ballistics solution
Up to the second calculations account for changes in wind, altitude, and temp
Unlike ballistically calibrated turrets, Sportsman is always accurate for all ammunition, at
all elevations, and in all conditions.
 
800 Yards:
While the Sportsman will provide a ballistic solution for distances further than 800 yards, it is best suited for the supersonic ranges typically involved in long range hunting. For accuracy at extremely long range, the 4500 Applied Ballistic Meter includes even more variables and allows input of Bryan Litz's library of custom drag curves in its solution, allowing for an even higher level of precision.

As you've likely read, the 4500 Applied Ballistic Meter contains the full Applied Ballistics solver for extreme long range accuracy and costs a couple hundred dollars more.   This Sportsman has software by the same company, but the Sportsman calculations are limited.  While it can still be used at long ranges, it will take more work on your part if you use it beyond that, as those custom curves are limited to the high-end meter.
