Entry GTI imaging platform — target depth and size display

The Garrett GTI 1500 is the entry GTI imaging platform, offering Garrett's target depth and size display at a lower price than the 2500. It helps newer hunters understand what may be in the ground before cutting a plug. Garrett aimed it at intermediate hobbyists who want more feedback than basic target ID numbers. Schoolyards, picnic lawns, and permission yards are good places to let the GTI imaging features guide smarter digs.
