Target offers the Bounty Hunter Gold Hunter Metal Detector, model no. GOLD-PL, for $55.99 with free shipping. (Amazon charges slightly more.) That's $2 under last month's mention and the lowest total price we've seen. (It's a current low by $8.) It identifies coin-size objects up to 6" underground and senses larger items up to two feet deep. It requires two 9V batteries (not included).
