Improved experience with the mobile application.

Firmware Update Labradar LX – April 22, 2025 – Version 1.4.1

Enabled series selection from the mobile application: Users can now change the active series
directly from the mobile application. New shots will be recorded under the selected series.
Implemented BC data transfer: Ballistic coefficient (BC) data is now transmitted to the mobile
application.
Added barometric pressure unit (inHg): The inHg (inches of mercury) unit is now available for
barometric pressure settings.
Enhanced CSV export: Meteorological data and ballistic coefficient (BC) values are now included
in CSV exports for individual shots.
Various minor bug fixes.
Compatible with the Mobile Application version 2.12.1 or later.

Firmware Update Labradar LX – January 24, 2025 – Version 1.3.2

Added a new graphical indicator that lights up green to clearly notify the user of a valid shot,
eliminating the need to closely monitor the screen to confirm successful data recording by the
Labradar.
Results are now processed and displayed 0.25 seconds faster.
Corrected the Fahrenheit to Celsius unit conversion when processing temperature information
provided by the user.
Fixed a bug where the projectile diameter, temperature, and barometric pressure inputs were
incorrectly applied to the last series instead of the current series. These parameters are now
correctly applied to the current series.
Various minor bug fixes.

Firmware Update Labradar LX – November 1, 2024 – Version 1.2.1

New user interface with enhanced navigation for series and shots, along with multi-page result
displays.

Release Notes

Labradar LX Firmware 1.5.3 beta – Release Notes

We are pleased to announce a new beta release of the Labradar software, focused on enhancing radar performance, data precision, and overall usability. This version introduces several significant improvements. Usability has also been improved with simplified operating modes. As a beta version, this release is made available for users who wish to evaluate the new capabilities and features ahead of the official release. We encourage users to test the software in real-world scenarios and share their feedback, observations, or suggestions to help us fine-tune the final version.

Changes and new features

Enhanced velocity measurement accuracy in noisy environments (better noise rejection).
Increased number of velocity data points stored in each shot’s CSV files (providing finer time/distance
resolution).
Automatic radar disarms after 15 minutes of inactivity to conserve power.
Improved ballistic coefficient BC calculation accuracy.
Automatic save and restore of current selected series, shot and results page at power-on.

Simplified operating modes:

The previous Rifle, Handgun, and Archery modes have been replaced with two new modes for easier
configuration:

Standard Mode

Velocity detection range: 20 to 1500 m/s (65 to 4921 ft/s)
Trigger: Internal or external microphone.

Suitable for:
Rifles, handguns, air rifles, airsoft guns, bows, crossbows and guns equipped with silencers
that produce a sufficient sound signature detectable by the internal microphone.

Quiet Mode

Velocity detection range: 20 to 350 m/s (65 to 1148 ft/s).
Trigger: Radar signal (Doppler trigger).

Suitable for:
Very quiet and subsonic rifles, handguns, air rifles, guns equipped with silencers, along with
bows and crossbows – if they produce sound signatures that cannot be easily detected by
the internal microphone.

Note: Battery consumption is higher in this mode.
