Bubble levels placed on monitors lose accuracy during panning due to acceleration forces and require time to settle back to accuracy.
Bubble levels work adequately for static shots without panning and remain an affordable solution for small rigs.
Frame line generators, built into or separate from monitors, display adjustable borders to help visualize frame edges.
Digital levels built into or separate from monitors show level information overlaid on the monitor and are generally more accurate than bubble levels, but still suffer accuracy loss during panning.
iPhone and iPod touch level applications are available at low cost and perform similarly to Steadicam-integrated electronic levels in compensating for acceleration.
All electronic level sensors, whether in dedicated devices or smartphone apps, use accelerometers to measure gravity and cannot distinguish between leveling and acceleration, requiring the operator to learn when to trust the indicator.
Electronic levels can drift with temperature changes.
Bubble levels should be positioned at the top of the monitor to remain visible during normal operation.
A monitor may be tilted at 45 degrees during operation, making only the horizon level useful as a reference.
The camera itself may be at a different angle than the monitor or sled, so levels should be adjusted to match the camera position and rechecked after monitor adjustments.
Electronic levels outperform bubble levels in compensating for acceleration when tested side-by-side.

Most tests of electronic versus bubble level accuracy were not conducted on an actual rig.
Some operators achieved consistent results with bubble levels alone over extended periods.
The cost and mass requirements of professional digital level systems were not detailed.
Whether smartphone level applications remain accurate during sustained panning on an actual Steadicam was not tested.
