BRAVA BACK ECHO
BRAVA, one of two horses at the centre of the controversial non-trier inquiry which eventually resulted in Jim Best receiving a six-month suspension, will have his first start for Best's wife Suzi today.
Devised by former University of Mississippi scientist Robert Derrow in close collaboration with ARS scientists, BASIS emits a pulse of acoustic energy and then gauges the strength and travel time of the back echo
to determine sediment's location and concentration.
Typically a front echo and back echo
will be seen as the sound wave bounces off the front and back surface of the casting.
