Hydrascope

Overview

The Hydrascope is a series of telescoping camera cranes manufactured by US-based Chapman/Leonard Studio Equipment. Unlike a classic crane with a fixed arm length, the Hydrascope arm extends and retracts hydraulically, allowing the lens height to be changed during a shot without repositioning the entire setup. Its waterproof construction is a distinctive feature: the crane is designed for rain scenes, spray, and dusty or harsh shooting conditions.

Operation is via a rotating handset, which the manufacturer claims replicates the booming feel of a dolly. The nose allows for quick switching between over- and under-slung operation and accepts standard Mitchell Mount heads.

Models and Reach

The series is categorized by maximum arm reach (in feet). Available models:

• Hydrascope 70
• Hydrascope 50
• Hydrascope 40
• Hydrascope 32 (also available with a sliding weight system variant)
• Hydrascope 20
• Hydrascope 15

Technical Specifications (Selection)

Example values for two models according to manufacturer specifications (Chapman/Leonard):

Note: Total weight depends heavily on the base and camera package (the Hydrascope 70 with Hydrabase, M7, and a standard camera package reaches approximately 15,000 lbs). Values for other models can be found in their respective data sheets.

On-Set Usage

The Hydrascope is primarily used where large, dynamic camera movements with variable height are required, such as in commercials, action, and VFX-heavy productions. The telescoping function allows for ascents and descents that a rigid arm cannot achieve. Due to its weight, hydraulics, and counterweights, operation requires an experienced grip team and a correspondingly stable or mobile base (e.g., UCS-Base, Hydrabase, or vehicle mount).
