Spire IV Enhancements
What's new on the Spire IV? The main differences are in the electronics and feeding logic. The Spire IV has been upgraded to work with the Virtue Ace wireless iFI platform. 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.
Spire IV iFI Wireless Technology
When the Spire IV is paired with the Virtue Ace, 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. And if the gun's eyes are turned off, dirty or if the Spire IV is used on a different gun, the Spire IV automatically transitions to the new proactive feeding mode, which will automatically feed with every shot until the stack is full.
Spire IV Upgraded Cosmetics
To help differentiate the Spire IV and give this latest model of the Spire family a new look, we've upgraded the color ring around the side with a more aggressive racing stripe that's also injected in stronger, more reliable glass filled nylon. Additionally, the side badges now feature injected Virtue logos, rather than a sticker badge.
Spire IV Toolless N-Charge
Near the end of the Spire III production, we upgraded the circuit board to allow for plug-n-play toolless installation of the N-Charge battery pack to make the transition to the Spire IV. All Spire IVs come with the electronics designed to install the Virtue N-Charge without the use of any tools.
