Wholeheartedly agree ShotOne,
While I was struggling to get to grips with the Wessex on instruments without ASE (stab system), my instructor sat there chewing gum while repeating 'scan, scan, scan' with the occasional 'RELAX!' thrown in for good measure. Great instructional technique that obviously helped me to master the exercise in no time. Hopefully he later made a better AVM than QHI.
