Eagle 3 Quick Reference Guide, “An Automated Test sequence guides the operator through a simple yet thorough tuning fork test. The operator may use the eFork in the remote control or traditional tuning forks.”
The eFork apparently has a patent pending. It is new technology, so the judge very well could require use and identification of the traditional assigned tuning forks.
However if no certification is available at the court as directed by the prosecutor, your wife’s first defense should be a preliminary motion to suppress or exclude for lack of foundation the speed reading based on inability to follow the prosecutor’s discovery instructions.
If the cert is at the court, then she can try a motion to suppress or exclude the speed reading for lack of foundation because tuning forks are not identified.
She should announce her motions immediately when her case is called, before the officer’s statement is read into the record and before she is sworn in for testimony. If any motion to suppress or exclude is granted, then she can move for dismissal.
