Furthermore, this model is equipped with the HAL2™ system.
HAL2 ™ is a Polish system in which the trigger, based on the Hall effect, offers unprecedented sensitivity (up to 500 points), responsive operation, whilst remaining unaffected by dirt and external light. The HAL2™ Widget is compatible with all standard triggers, allowing you to choose from the numerous models available on the market and further personalise your replica. The built-in Bluetooth® Low Energy module enables an easy and stable connection to your phone whilst ensuring the replica’s battery lasts for a long time. Simply switch it on and you can configure the settings straight away. Meanwhile, a range of sensors ensures the replica operates faultlessly and prevents damage should a problem be detected.?

With the free Specna Link™ app from Google Play or the App Store, you’ll discover the full potential of the HAL2™ system. This intuitive tool, designed for use whilst wearing gloves, allows you to quickly adjust the replica’s settings to suit the requirements of a particular shooting scenario. You can create several profiles for a single replica – each with different settings – or set up accounts for several different replicas. Then all you need to do is select the relevant option in the app and you’re ready to play!?

- trigger sensitivity adjustment,?
- precocking for a faster response when the trigger is pulled,?
