Terrapin-X TDH Firmeware Update

Terrapin-X TDH Firmeware Update

We are excited to announce a new firmware update for the TERRAPIN X, which will be available in Australia from 1 am on the 6th of June AEST.

The new TDH protocol allows the TERRAPIN X, to connect with certain other devices or dedicated ballistic smartphone apps that have partnered up with the Safran Vectronix Terrapin X team.

We are especially happy to let you know that the update will make your Terrapin X capable of connecting to the famous Hornady 4DOF ballistics app.

TERRAPIN X now fueled by Hornady

The Hornady 4DOF (4 Degrees of Freedom) ballistic calculator determines trajectory solutions based on the projectile drag coefficient along with exact physical modeling of the projectile, it's mass and aerodynamic properties. The free app version (available for Android and iOS) of the Hornady 4DOF calculator allows shooters to get highly accurate solutions even in areas lacking wireless connectivity. Since the release of the app in August 2016, its user base has grown to over 300000 active users – a clear testament to the high quality of the Hornady 4DOF ballistic calculator.

We are excited to announce that the TERRAPIN X now connects via Bluetooth to the Hornady 4DOF app. This means that when a connection is established, the TERRAPIN X sends the measured distance, azimuth, and inclination to the Hornady 4DOF app. The result is a much faster calculation of the ballistic corrections by the app, as otherwise, this data would have to be manually entered by the shooter. Just as the Hornady 4DOF app, this new functionality is free of charge for TERRAPIN X owners.

In order to connect your TERRAPIN X to the Hornady 4DOF app, you will only have to update your TERRAPIN X to the latest firmware version (TerPin 13.01). After having successfully updated your TERRAPIN X you will able to connect to the Hornady 4DOF app.

Detailed instructions on how to do this you will find via the following link:
