Maztech
20 in hotshoe-to-I/O cable that sends X4-LRF range data directly to an installed X4-FCS.

The Maztech X4 FCS-to-LRF Cable 20 in links the X4-FCS hotshoe to the X4-LRF I/O Accessory Port. A range measured by the LRF becomes available to the FCS without manual distance entry, so the projected aimpoint can update from the measured target range.
The cable leaves the X4-FCS I/O port available for either Maztech wired remote. The 20 in version is best matched to the physical placement of the two devices: short for an above-scope or close front-rail layout, long for a side-rail or widely separated layout.
Add the X4 FCS-to-LRF Cable 20 in to your build and see how it enhances your platform.
