How is the SFR / SFR vario system attached to the shaker?
The SFR and SFR vario are delivered with fitting screw sets for most common shaker trays. With these the readers can be screwed securely to your shaker tray, so they are held in position during shaking. All data transfer is wireless (via Bluetooth), so there are no additional cables or connections running into or out of the shaker.
