The new Kestrel Elite Weather Meter with Applied Ballistics which has been referred to as the Kestrel 5700, is an updated version from the Discontinued Kestrel 4500 Applied Ballistics Meter in November of 2015. That being said... functionally, you're not getting more environmental or ballistic features. So don't feel the need to upgrade unless you find the other exciting changes necessary.
If you select the Bluetooth Kestrel LINK model, you'll want to download the Kestrel LiNK Ballistics app to your smart phone to load your guns / ammo to the meter. The new Kestrel Meters with Bluetooth include the software necessary to communicate wirelessly at a range of up to 100 feet with a clear line of site (walls or obstacles will effect this range).
There is a free app for both Android and iPhone for the Ballistic Profile Loader. This is what you use to load your Gun/Ammo combinations to the Kestrel. You can NOT load your gun profiles from the Dongle.
The Kestrel 5000 USB cable is an option. This is most common to use with multiple meters. Example being, you need 20 AB meters, and you want to save money by not purchasing the LINK meters. You could get 20 non LINK meters, with just 1 cable and load up all your meters with the Mac/PC version of the Profile Loader.
All 5000 series meters will have both a bright green backlight, which is great for even high sunlight conditions, and a night-vision preserving backlight. The red night vision (NV) backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. (Note: This 'night vision' is not compatible with night-vision equipment.) Basically, with the red backlight, your eyes don't need to adjust when looking from your meter to the horizon in night time use.
This Kestrel 5500 with Kestrel LINK will work in conjunction with compatible range finders like the new Bushnell Elite 1 Mile CONX range finder you've been reading about. It will also work with many other apps on the market for ballistics and weather functions. It's the most popular for ballistic applications due to the compass with crosswind functions.
The Kestrel applied ballistics meter combines sophisticated environmental sensing features with long-range shooting ballistics information in one hand-held device. The built in Applied Ballistics software provides all of the following:
The Kestrel Shooter's Weather Meter with Applied Ballistics Technology measures up to 15 environmental parameters and allows users to select from either G1 or G7 ballistic coefficients (BC) when calculating a trajectory at the range. The handy, portable meter also offers the “Litz” measured BC library of over 225 bullets, which is considered to be the most extensive source of measured data for modern small arms bullets. Users can also train the Kestrel Shooters Weather Meter with Applied Ballistics software to match a specific rifle based on observed impacts at long range with the ballistics calibration feature, which offers even more accurate data points for users to rely on. With easy access to more accurate BC data, shooters have everything they need to make a much more precise trajectory calculation in a compact and durable Kestrel meter design.
The Kestrel Shooter’s Weather Meter with Applied Ballistics allows users to select either G1 or G7 ballistic coefficients, or to be even more specific and select from an entire library of Applied Ballistics Custom Curves for more than 200 common long-range bullets.
Please note that access to the full Applied Ballistics Custom Curve library REQUIRES the Applied Ballistics Profile Loader via the Cable, or loaded from you smartphone, free from the App Store or Google Play. For full gun and bullet profile customization and backup, we recommend our customers purchase the unit with Bluetooth wireless data transfer for ease of use and functionality.
Read up Books or watch the DVD's by Bryan Litz of Applied Ballistics and the Litz Library. Books include Applied Ballistics: Accuracy and Precision for Long Range Shooting: A Practical Guide for Riflemen, and Applied Ballistics for Long Range Shooting.
Kestrel 5700 Elite Weather Meter with Applied Ballistics with integrated Bluetooth® technology offer the ultimate in portable and accurate environmental data. Now, both real-time and logged data can be transferred wirelessly and automatically to a MAC/PC, or Smartphone. Yes, even iPhone. It also connects via LiNK to the Bushnell CONX Range Finder where you can view results from the AB Kestrel right on your Range Finder.
You can enter all your data manually except for custom curves. There are several custom curves preloaded, but if you want a different one, you have to download it from your phone.
You can load up to 16 guns, one bullet each. In the case where you have multiple ammo types for a given rifle, you have to enter a whole new gun for each ammo type.
The main differences between the two models is The Applied Ballistics model has a different truing application with drop scale factor, it has bullet length as a standard gun input (used to calculate spin drift) offers +\- angle input and has the ability to use G1,G7 and custom drag profiles. The unit comes Pre loaded with 7 custom curves, and the Gun loader will have over 100 custom drag profiles to use.
Please see this simple manual explaining how it works.
