The SIRUI CVM-145P+CT5X is a modular monopod kit built for run-and-gun shooters who need to switch quickly between a monopod, an extension rod, and a tabletop tripod on the same outing. Patent One-Step Height Adjustment: A single twist of the lock fast-extends or retracts the monopod, even with heavy equipment attached. Side-Loading Fluid Head: Tilts -60° to +90° and automatically returns to position on release, for smooth, accurate video. 3-in-1 Modular Design: The mounting plate, leg, tripod base, and rubber pad combine into a monopod, an extension rod, or a tabletop tripod. Switchable 3/8" or 1/4" Thread: Self-adaptive thread size fits heads, gimbal stabilizers, and phone clamps. Automatic-Lock Quick Release: Pull down once to release, then mount equipment with both hands and let the plate lock automatically. Rated -30°C to 70°C: Tested to 35kg vertical and 25kg transverse pressure loads for harsh-environment reliability.
