Yesterday I received my GeoBallistics WeatherFlow WEATHERmeter . It’s a new product that sticks to the budget friendly side of measuring important environmental data. It will measure wind speed, temperature, barometric pressure, and humidity. The GeoBallistic WeatherFlow WEATHERmeter uses a software called BallisticsArc that is available for both android and apple users. Today I want to give a brief overview of the BallisticsArc app as it uses all of the data from the WeatherFlow WEATHERmeter to complete an environmentally correct firing solution.
BallisticsArc Rifle Page
The first page you are brought to when you open up the BallisticsArc app is the Rifle page. This is where you are going to input the information about your rifle and ammunition. As with any ballistic program make sure to check your work. Bad data in will result in bad data out.
If you are using the free version of the app you will not be able to delete the sample rifle. I have the premium version and have deleted the sample rifle and have replaced it with my rifle data. The data it asks for is shown below.
Skipping over the bullet information you will need to input information about your rifle. The sight height, zero range, twist rate, and velocity of the bullet are all required. If you have an elevation or windage offset you will also need to provide that information in the appropriate places.
Next you will set up a list of parameters in the GeoBallistic Overlay section.
The first one is your vital size overlay. This will give you the maximum range in which you can hit a target of a specified size without dialing or using any hold overs.
Next you can set an energy threshold which will tell you when your bullet has reached a specified ft-lbs of energy. Both the vital size and energy threshold overlay are useful to hunters who want to know the maximum distance they can use their zero to take game without adjustment and the maximum distance they can ethically take a shot.
Finally we can program in a velocity thresholds. This threshold can be set at a set velocity and will normally be used to indicate that our bullet has gone transonic. This is generally regarded as the maximum effective range of the bullet however many experienced shooters can and will shoot past this distance.
Ballisticsarc Bullet Library and Manual bullet additional features
The first thing you will want to do is find the bullet that you are shooting from the rifle. If you intend to shoot multiple different bullets from the rifle you will need to make multiple profiles of the same rifle with the different bullets. The app uses the JBM bullet library and has a majority of bullets available, however if the bullet you intend to shoot is not listed you will need to manually add the bullet information. The bullet library allows you to select caliber and even bullet weight to narrow down your list of choices.
BallisticsArc Weather Page
The next page after all of your rifle and bullet data has been saved is the weather page. If you are not using their WeatherFlow WEATHERmeter to collect this data this is where you will manually input the environmental information. The app will use you local internet connection and the compass in your phone to find the information needed. You also have the ability to manually enter this information if you so choose.
Weather page: online weather
The bottom section of the weather page is the online weather section. If you click reload you will provided with a list of weather stations in your area. If you select a weather station it will then populate all the information from that site as well the time the data was last refreshed at the weather station. Once this has been done you can click either use button to use that information for a ballistic solution.
Below I selected the Penn Yan weather station and imported the data into the fields above.
Weather Page: wind and atmosphere
You can also manually input the wind and atmospheric information if you choose. The blue compass next to the direction (deg) field will allow you to use your phones compass. In order to get a correct reading stand in the direction the wind is coming and point your phone into the wind and click the compass. Pictured below is the proper way to point your phone. This will also come into play when finding the shot angle and shot bearing in other features of the app.
BallisticsArc Hardware Page
If you have the GeoBallistics WeatherFlow WEATHERmeter you can bypass the weather page and get everything you need at your location. I will be covering the weather meter in part 2 of this review at a later date.
Once your weather meter is paired it will start giving you real-time data. With your device facing the direction of the wind and the WeatherFlow WEATHERmeter facing back first into the wind (front facing towards you) you can then hit take sample. I used a 5 second interval and below is the information I got. By selecting the use button the wind speed, direction, and density altitude will now be used in your firing solution.
BallisticsArc Chart Page
Once you have the environmental factors covered you can move on to getting a firing solution. Clicking the blue button next to the location line will use gps on your phone to get your location. Next you will point your phone at the target and click the angle button. This is best done behind the rifle while aiming at your target and will get you your shot angle. Next click the compass button to get your shot bearing. This will complete the data needed to apply the wind speed and direction into a firing solution.
In the chart above you will notice that there are 3 lines that are outlined. These are you GeoBallistics Overlays. The first gray overlay is the maximum distance for your vital size inputs. The red outline is you energy threshold. This is the distance at which your round is at the minimum ft-lbs of energy you input. Finally the yellow outline corresponds to your velocity threshold. This is the point where your bullet will drop below the velocity that you input.
BallisticsArc Map Page
Next up is a page that will allow you to find your location and map out targets or known points. Using a google earth overlay you can get a bird’s eye view of what is around you. You can drop a pin for your location as well as target. You can also connect the dots with a GeoBallistics Overlay showing you your preset thresholds. This information will give you the distance to your target and the corrections for them. It will also tell you the corrections and distances for each of your thresholds.
BallisticsArc: Competition Page
One of the most attractive parts of the premium BallisticsArc app is the Competition page. You are able to set up stages and targets before hand. Before running the stage all you need to do is collect environmental information from the WeatherFlow WEATHERmeter and it will give you all the information you need to dial or hold for each target on that stage.
When entering in the targets you will follow the same steps as the chart page. This includes location, shot angle, shot bearing, and finally the specific range to the target you are loading. You can save range cards and access them at any time. Once all the information has been added and the environmental data input you will get a firing solution for each target.
Stay tuned for part two of this review. I will be testing the GeoBallistics WeatherFlow WEATHERmeter against a weather station to ensure that it is giving accurate data. Part 3 will be coming soon after that where I run the firing solutions against the Applied Ballistics program to see which is more accurate with their firing solutions.
