Hofmann Geodyna 7100 Features
Digital LED Display with Touchpad Controls
The Geodyna 7100 features a weight-tray integrated touchpad with an intuitive LED display for streamlined operation. All balancing functions are controlled directly from the weight tray position, eliminating unnecessary movement around the machine and reducing cycle time. The clear digital readout provides instant weight values and placement guidance for both static and dynamic balancing modes.
Semi-Automatic Data Entry with easyALU Technology
Equipped with a user-friendly gauge arm featuring easyALU assisted rim measurement technology, the Geodyna 7100 simplifies the data entry process.

Split Weight Mode for Aesthetic Balancing
The split weight mode feature ensures accurate balancing while maintaining the wheel's visual appeal by concealing weights discreetly behind spokes. This mode calculates optimal weight placement to achieve perfect balance while keeping weights hidden from view, ideal for custom wheels, alloy rims, and high-end vehicles where aesthetics matter as much as performance.
QuickNut Manual Wheel Clamp
The QuickNut manual clamping device provides secure wheel attachment to the balancer shaft with user-friendly operation. Designed for ease of use and reliability, this clamping system facilitates efficient wheel mounting and guarantees stable positioning throughout the balancing cycle. The manual design offers tactile feedback for proper tightening without risk of over-torque damage to wheels.

By selecting the vehicle make and model, technicians can compare available mounting tools and assess their benefits, ensuring proper wheel mounting for accurate balancing results across diverse vehicle types.
Protective Wheel Cover
An included wheel cover prevents objects from flying off during the spin cycle, protecting technicians from potential accidents. This safety feature is essential for high-speed balancing operations and provides peace of mind when working with damaged wheels, loose tire beads, or wheels with debris that could become projectiles during rotation.
