When the Spire IV is paired with the Virtue Ace or iFI compatible boards, the loader maintains instant communication with the marker's eyes which allows for significant improvements as both the gun and the loader are now synced together for faster and more consistent feeding, stopping and idle performance. This new feeding technology allows for a tight integration between the loader and the gun and also maintains backwards compatibility on guns without iFI technology using the new Proactive Feeding logic pioneered on the CTRL loader. The Spire IV has been upgraded to work with the Virtue Ace wireless iFI platform. This is the same proven technology incorporated into the CTRL loader, which works more consistently and reliably on every type of marker. Now your Spire IV starts feeding the instant the first shot is fired, and continues to feed automatically, without relying on continuous sensor readings until the stack is full. Unlike previous Spire models, which required constant sensor readings from every shot (with the potential for adding in extra unnecessary spins while shooting, and could potentially result in slow rates of fire from a sensor malfunction), the Spire IV features the new Proactive Logic. The Spire IV features all new proactive feeding logic. Toolless electronics for easy N-Charge battery pack installation. Virtue iFI wireless integration with compatible markers.
