Chronograph Log was developed to record your bullet velocities, from your Chronograph, onto your iOS device. No more writing everything down on a pieces of paper to be lost in your range bag. When your friends ask about the loads you are using, you can pull out Chronograph Log and give them accurate info instead of guessing. Send them an email or message on the spot. Share your favorite loads via eMail, Facebook and more. Chronograph Log was primarily developed for USPSA IPSC and IDPA, where Minor and Major Power Factors are very important. It will color code those entries based on their velocities. Note that the Power Factors can be ignored if you are tracking rifle loads or don’t care about Power Factors. Note: This application is not a chronograph. You will need to enter readings from your chronograph into the Chronograph Log app. • Define: Bullets, Guns and Powder in the database. • Record velocities for each round from your chronograph. • Automatically calculate Average, Min and Max velocities. • Color coding to show each velocity’s Power Factor. • Export full tables to Mail. • Export favorite loads to Messages, Mail, Twitter or Facebook. • Backup / Restore to Dropbox. • Bluetooth integration with Competition Electronics "ProChrono Digital" using their "Digital Link" module.

About

Speed Tracker air

Read full description

SPEEDTRACKER air is an amazing piece of technology. Developed by a team of German and Czech Engineers. Case design in the Netherlands, mathematics and programming in Berlin and Prague. Tested by gunners in the Czech Republic , Italy, Canada and the UK. The radar beam formed by incredible lenses with an aluminium foam filter (patented) in Bohemia. The heart is a 120 GHz radar SiR-chip – made in Germany. These wavelength empower us to generate the biggest radar cross section of bullets on the market. This results in an extremely high accuracy and with a lot of detections in the first meter. The BULLETSEEKER air is detecting the bullet up 1000 times in the first 100 cm. This is the true muzzle speed and it is not affected much by wind and air pressure. The reason for this is the very short wavelength of only 2.5 mm - competitors are using 10 times longer radar waves. Certified with CE and FCC.
