Purchased August 25, 2021, sat on my rig, no longer needed. Has some quirks but helpful in judging level and balance. From the manufacturer:The SmartCAM Zen Digital Level from SmartSystem provides accurate level readings for your Steadicam or other stabilizer systems. This system uses dual LED bands to display up to two axes simultaneously. In addition to roll, tilt, and pan, the Zen can display roll/tile, roll/pan, tilt/pan, and roll/side-to-side combinations. Four display speeds, auto-zeroing, and a beta-zeroing by gesture function make it easy to set the display for multiple takes. The Zen digital level can be powered via USB or a 2-pin LEMO input.
