How to Operate Kestrel 4500 NV Shooters Weather Meter
The Kestrel weather meter is an invaluable tool for shooters. While the standard model Kestrels can record wind and atmospheric conditions, the advanced Kestrel 4500 Shooter’s Weather Meter with Applied Ballistics incorporates a built-in ballistics program developed by Bryan Litz of Applied Ballistics. This is a very powerful tool, but it can be a bit complicated to program at first.
In this detailed 22-minute video, John McQuay of 8541 Tactical shows how to input firearm specs, MV, and BC into a Kestrel 4500 NV (Applied Ballistics model). This handy unit combines a Kestrel Weather meter with a full-fledged ballistics computer.

Step-by-step the video shows how to set up all the important variables. The video shows how to input Muzzle Velocity, Bullet BC (G1 or G7), Zero Distance and the other key ballistics variables. In addition, the video explains how to input gun-specific data such as bore height, barrel twist rate, and barrel rifle twist direction (right-hand vs. left-hand). (Twist direction comes into play in long range spin drift calculations). If you own a Kestrel 4500 NV (Applied Ballistics), we think you’ll find this video helpful — particularly when it comes to setting up some of the lesser-known data items. The video also offers tips on navigating through the menus most efficiently. |
Horus ATrag Ballistics software is now embedded in Kestrel 4500 NV Pocket Weather Trackers, eliminating the need for a PDA. Since the ballistics software is built into the Kestrel unit, environmental data automatically flows from the Kestrel side to the ATrag solver for accurate and instant ballistics solutions. You don’t have to punch in wind speed, temp, or air pressure — that’s all done automatically. The 4500 NV Weather Tracker is IP67 waterproof and MIL-STD-810F rugged. MSRP for the Kestrel with Horus Ballistics is $619.00 (non-Bluetooth).
