The flexible ballistic turret (BTF) can be configured separately with three different types of rings and attached with a single click. You can use it as a top or side turret and combine it with all available sights. In this way, you can always have the target in sight at the desired distances. If you use the ballistic turret as the top turret, it can compensate for a falling bullet trajectory. If you instead use it as a side tower, it can compensate for drift or be used to estimate the look ahead. A locking mechanism also prevents accidental twisting. With the parallax turret on the Z8i, you can set up a parallax-free image that can be quickly adjusted – even in shooting position. The latches at the 100 m mark allow you to easily and reliably set the parallax tower even at dusk.
