Leofoto FDM-03 Binocular Rangefinder Rail Kit

The Leofoto FDM-03 is the most powerful rail system in the FDM series and was developed for maximum stability, reach and modularity. With its extra-long rail, it is particularly suited to complex multi-optic setups and professional applications in which several devices must be used precisely at the same time.

Maximum length for maximum flexibility

The BPL-320 rail, 320 mm in length, offers significantly more space than the FDM-01 and FDM-02. This allows several optics to be mounted at the same time and positioned optimally.

This enables complex setups such as:

• Spotting scope + rangefinder + additional device (e.g. Kestrel)
• Binoculars + thermal imaging + laser
• Camera + spotting scope + measuring system

The longer rail also improves balance and reduces disruptive micro-movements.

Working in parallel with several optics

The FDM-03 is designed specifically for the parallel use of several devices. All components stay mounted and ready for use at the same time, which completely eliminates unnecessary reconfiguring.

This significantly increases efficiency in the field, especially for:

• Long Range Shooting
• Hunting and observation
• tactical applications
• professional spotting work

Dual-Arca system for maximum modularity

The rail has an Arca-Swiss profile on both sides (top and bottom), which allows components to be positioned freely along the entire length.

In addition, the system offers numerous 1/4" and 3/8" connections for further accessories and extensions.

The integrated spirit level allows quick and precise alignment for smooth panning and accurate observation.

Integrated ball head for dynamic applications

The specially adapted LH-22 ball head allows independent movement of one optic. This makes it possible to actively track a target while other devices stay stable.

Rugged CNC construction

Made from 6061-T6 aluminum and fully CNC-milled, the FDM-03 offers very high structural strength at a controlled weight.

The system is designed for a load capacity of up to approx. 5 kg and is therefore also suitable for larger optics.

The design is consistently geared towards stability, repeatability and durability.

The FDM-03 is supplied as a complete kit and consists of:

• BPL-320 Dual Arca Rail (320 mm)
• LH-22 ball head (FDM version)
