This kit consists of 2 parts:
NR-200 Double Arca Long Rail ( 230mm/ 9.06in)
This rail clamp combo features an Arca-dovetail on both sides of the rail, which allows for multiple mounting options at any position. The bottom profile enables the rail to be moved to any position in an Arca clamp, accommodating a variety of installed equipment. A large top-mounted bubble level allows for quick and easy leveling of the rail for level panning and accurate measurements.
LH-22 Mini Ball Head (FDM ver.)
The LH-22 Ball Head with Arca Clamp is a versatile and adjustable accessory that is designed to securely hold your spotting scope or camera. With its ability to independently maneuver one of the installed items, it is perfect for tracking moving targets. Please note that this is not a standard LH-22, as it is permanently attached to an Arca clamp, which allows for easy attachment to the rail.
This is a perfect way to use a rangefinder and scope or binoculars. All leophoto products are extremely well made. Customer service is awesome.
