TECH REVIEW: Kestrel 5700 Elite with Applied Ballistics Software

Kestrel Wind Meter F-Class John Applied Ballistics

The 2021 NRA F-Class National Championships are underway right now at Camp Atterbury, Indiana. The Mid-Range Nationals concluded yesterday with the Team Match, and the Long-Range F-Class Nationals commence today, July 27, 2021 and run through Friday, July 30th. For F-Class competitors, making the right wind call is a vital skill. Many shooters and team wind coaches will be using Kestrel Wind Meters, widely regarded as the best on the market.

Camp Atterbury F-Class Championships

This article reviews the advanced Kestrel 5700 Elite Wind Meter with sophisticated ballistics capabilities. Our review features three videos by F-Class John that show how the Kestrel 5700 Elite works with Applied Ballistics APP software and LiNK connection.

This Part I Video starts with a basic Kestrel Anemometer (blue case, 00:00-00:40) wind meter. Then reviewer F-Class John looks at the “smart” Kestrel 5700 Elite with Applied Ballistics functionality and LiNK Bluetooth connectivity. John explains the many features of the Kestrel 5700 and how it holds a powerful ballistics calculator in the convenient, easy-to-tote Kestrel package. With the Kestrel 5700 Elite, once you enter data about your bullets, velocity, zero, and rifle, the Kestrel can calculate come-ups and wind corrections. If you don’t yet own a Kestrel, we highly recommend you watch this series of videos that explains advanced Kestrel features in detail.

This Part II Video shows the key features of the advanced software APP used by the Kestrel 5700 Elite unit with Applied Ballistics. The Kestrel 5700 can “talk” to a mobile device that runs the Applied Ballistics software APP that contains bullet databases and allows you to enter key information such as muzzle velocity, bullet BC, zero distance, velocity, wind, and environmental factors (altitude, temperature etc.). There are also gun-specific factors such as scope height over bore and barrel twist rate. The video also explains how “range cards” are created and how to view them with your Elite Ballistics-enabled Kestrel. John notes: “The APP is great because you don’t have to fiddle with the Kestrel’s buttons. It’s much easier to enter data and change settings with the APP.”

This Part III video shows how to determine true wind direction by aligning the SIDE of the unit into the wind. You essentially want to set the unit 90 degrees to the wind direction so the impeller runs as slowly as possible. Then, after you set your target distance (See 3:03), the unit can give you precise come-ups for your intended target (10.28 MOA for 559 yards here). The Kestrel then calculates the cross-wind correction as well (See 3:12).

Lapua Ballistics App Basics — How to Get Started

Article by Matti Paananen
As smartphones and tablets are constantly developed, ballistic software and Apps are also improving, and with their help our ability to hit targets can improve significantly. This is a short introduction on why and how to use a ballistic calculator, namely the Lapua Ballistics App, and a few pointers that will help you use the App effectively.

CLICK HERE for FREE Lapua Ballistics App USER GUIDE

Ballistics software and Apps are designed to help shooters and hunters make calculations to hit distant targets or take down game in the field by offering ballistic solutions. Lapua Ballistics is the first App utilizing the 6DOF calculation model.

Toying around with ballistics apps is always fun, but effective use of ballistic software requires general understanding of how they work. The App gets information from the user and by using mathematical formulas it provides the solution that will give the user a solid starting point to hit the target.

However, it is also important to remember that the App can’t think — it only calculates a solution based on your parameters. You will not know the error until you have already fired the shot.

1. SET UP YOUR SCOPE RETICLE AND RIFLE
Scope manufactures use different units per click, so it’s important that you use the correct unit in the App. For example, in your scope, one click can be 0.1 mil, 1/4 MOA, [or 1/8 MOA depending on the model]. You can find this information in your scope manual and also usually from the scope turrets. Setting your scope reticle is very important, partly because if you use the wrong unit in the App, the ballistic solution will not match your scope. To set up your scope reticle in Lapua Ballistics, go to Manage Rifle / Cartridge Data –> Add Rifle Cartridge Data (or choose to edit a Rifle/Cartridge combo you’ve already set up) –> Reticle –>.

Another thing to setup in Lapua Ballistics is your scope height, i.e. Line of Sight to Bore in the Manage Rifle / Cartridge Data window. This is the distance between the center of the scope and the center of the bore. The default height is 45mm but with tactical rifles, the height can be even 70mm. So check! The height is easy to measure with a ruler. Then there’s also the twist rate of your rifle to set up — look it up in the rifle manual, it can also be stamped on the rifle barrel. The rifle twist rate is needed to calculate spin drift and bullet stability. Spin drift should be taken into account with longer distances, and it can be enabled or disabled in Lapua Ballistics.

2. SET UP YOUR BULLET CHOICE
You can add your bullet of choice from the bullet library, where you find all Lapua bullets. It is also possible to add information manually. In this case, you will need bullet weight, the ballistic coefficient BC and muzzle velocity. The Ballistic coefficient can be given in G1 or G7 values. G7 is designed for low-drag bullets with a boat tail and G1 is used for more traditional flat base bullets. Lapua on the other hand uses Doppler radar-based data to calculate a more accurate ballistic trajectory for Lapua bullets by 6DOF model. Anyway, it is good to remember that the ballistic coefficient changes with velocity, so all changes in a flight path cannot be predicted.

The following thing you will need to set up is the bullet’s actual muzzle velocity. You can reverse engineer the number based on your drop or by using a chronograph. It is good to remember that more rounds you shoot, the better average velocity you will get.

Lapua Bullets 6DOF Ballistics App Hunting G1 G7

Because temperature affects muzzle velocity, it would be good to shoot velocities in different temperatures and write them down. Those notes can be used with Lapua Ballistics as it is possible to set up the powder temperature variation in the App.

3. SET UP WEATHER CONDITIONS
Lapua Ballistics has settings for temperature, air pressure, and humidity. All these affect the ballistic solution and the chance to hit the target. In a nutshell, temperature affects the powder’s burn speed and in that way the bullet velocity. Air pressure and humidity also affect bullet drag.

If you are shooting approximately on sea level, you do not need to change air pressure values, but if you are shooting or hunting in mountain areas or where there is lot of elevation difference, you might want to check the air pressure. On sea level, the atmospheric pressure is 1013 hPa. The higher you go, the less air pressure you will have and thus less bullet drag. Some like to use handheld weather and wind meters that have a function to get actual air pressure and humidity, however the Get Current Weather function in Lapua Ballistics will give you the air pressure reading from your local and most close weather station, provided that your app is allowed to use your location data.

Temperature is an important variable. To understand how velocity change in different temperatures, only way is to shoot and keep notes. Some ballistic software and apps have values for muzzle velocity in different temperatures. The user needs to input muzzle velocity in different temperatures in order to software to calculate the effect. More velocities in different temperatures the user adds, the more accurate the calculation will be.

4. SET UP A BALLISTIC SOLUTION
After we have set up our own rifle / cartridge data, there are few things that need to be taken into account when shooting: the distance to the target, the wind and our shooting skills. Distance can be measured for example with a laser rangefinder and then put in. Wind can also be measured with a wind gauge but it is important to remember that the wind in the target area can be very different from that in the shooting position. Lapua Ballistics gives a ballistic solution based on stationary wind, so in the end, the shooter’s task is to estimate how much the wind factor will be.

It’s good to remember that Lapua Ballistics is a starting point and designed to assist the shooter. Software and apps have ways of helping us adjust the sight and predict the ballistic solution but they will not replace the shooter. We still have to pull the trigger and record our range data. By keeping good range notes and with the support of good ballistic software like Lapua Ballistics, we should be able hit in all environments.

Kestrel 5700 Elite Offers Ballistic Solutions for Multiple Targets

Kestrel 5700 elite link mobile app applied ballistics

GunsAmerica just released a detailed review of the recently-upgraded Kestrel 5700 Elite with LiNK, a software-enabled weather meter. If you compete in practical/tactical events (with targets at multiple distances), or campaign a wide selection of rifles, or shoot at Extreme Long Range, you may want to get this device. It offers unrivaled capabilities in a small package. This impressive handheld device combines weather-monitoring capabilities with a full-featured, very sophisticated ballistics solver that now calculates out to 5,500 yards. Using Bluetooth and LiNK technology it communicates with your mobile device as well as LiNK-enabled laser rangefinders.

Why You May Want to Buy the Kestrel 5700 Elite with LiNK:

— The Device can hold up to 30 different rifle/cartridge profiles, each with its own BC and muzzle velocity for ballistic calculations.

— The Device registers current windspeed, wind direction, air temp and pressure, and other variables, and then sends that info via Bluetooth to your smart-phone, updating the ballistic solution. It essentially updates your drop chart in real time.

— The Device “talks” to your smart-phone, providing a large, convenient display that can show both elevation clicks and wind corrections. The display essentially replaces your data card. The Smartphone integration also makes it easy to modify your different rifle/ammo profiles.

— The Device gives you come-ups and wind corrections for multiple targets (at various ranges). These can be displayed in a list, ordered by distance. This is a great feature, check it out:

Quick and Accurate Solutions for all Cartridge Types — Big and Small
The Kestrel 5700 Elite can work for everything from a .22 LR to a .50 BMG. In fact, GunsAmerica’s tester used the Kestrel 5700 for a 6.5 Creedmoor shooting out to 1070 yards, and then used the solver for a .22 LR match out to 300 yards. The data for the 6.5 CM was spot on, but even more remarkably, the holdover for the .22 LR was precise to 0.2 mils at 300 yards. The GunsAmerica Reviewer, Ian Kenney, was impressed:

“I think the best testament to the capabilities of the Kestrel 5700 Elite were on display at a recent range trip where I was getting my modified Ruger 10/22 ready for an upcoming precision rimfire match. I started out with a sort of hodgepodge of information, using an unconfirmed BC [for Eley Force ammo] that I’d heard from a friend along with a muzzle velocity that another friend had gotten with the same ammo. I created a new profile using this assortment of data and entered in target distances for 200 and 300 yards. Imagine the smile on my face then when I got hits at both distances with the elevation setting only being 0.2 mils off at the farthest target.

It’s impressive that the technology allowed me to only be 0.2 mils off with .22 LR ammunition at 300 yards, which is only about two inches, all the while starting out with imperfect data. If that’s not an exquisite demonstration of the versatility of this technology, to be able to toggle between such diverse calibers and get accurate data to long distances, I don’t know what is.”

Kestrel 5700 Elite Special Capabilities
The LiNK Ballistics App lets you set up multiple targets for single-screen viewing. The Kestrel 5700 Elite can also be wirelessly paired with LiNK-compatible laser rangefinders. Being able to instantly accees exact target range data allows a more rapid and and more precise ballistic solution.

In addition to the ballistics solver capabilities, the Kestrel 5700 Elite is a comprehensive weather meter that monitors all key variables including: wind speed and direction, temperature, humidity, heat index, pressure, and altitude. Your data log can be transferred to a iOS/Android device wirelessly with the LiNK wireless communication option and Kestrel LiNK app. The 5700 Elite now uses a single AA Battery housed separately from the circuit board.

More Features of the Kestrel 5700 Elite
The Kestrel 5700 elite has almost too many features to list. One notable capability allows you to quickly “tune” a profile by entering field-confirmed data. Kenney explains: “You can go into the gun profile and calibrate the muzzle velocity by telling it how much elevation you used to get a hit, effectively truing your dope in short order. This is ten times faster than logging it in your data book, going back to an online solver, and making adjustments[.]”

Ian Kenney’s Kestrel 5700 Elite Review is very thorough, and contains many more details and insights than we can cover here. For anyone considering purchase of a high-end Kestrel, we strongly recommend you read Kenney’s review. Ian concludes: “I’m not going to lie… with an MSRP of $699, I recognize [the Kestrel 5700 Elite] may not be for everyone. Considering how often I shoot long range and the number of rifles that I have, it makes sense for me[.] The Applied Ballistics solver also gives me the confidence that my dope is going to be accurate no matter what conditions I might find myself in. So for me… this Kestrel delivers the goods.”
