This is a generic mechanical sector scanner, traded in by a customer upgrading to the ScanX Pro.
It is suitable for very basic imaging: yes/no canine pregnancy detection, for example. It is not veterinary grade or suitable for advanced scanning. It is best suited for someone taking their first steps into scanning on a very limited budget. Expect to need to upgrade to a better machine later down the line.
This is not a stock item (this is the only one of its kind we have) and we cannot provide you with training on this specific machine. We highly recommend you accompany your learning with this book on canine pregnancy scanning.
