ABSTRACT:
A method for making a search coil frame assembly for a metal detector, the method comprising providing a plurality of frame members, each having an aperture therethrough, providing selected ones of the frame members, respectively, with first, second and third grooves in face surfaces thereof, the grooves being formed so as to extend substantially around the apertures and to an edge of the frame member, placing electrically conductive strands in the grooves, and bonding the frame members together to close the grooves with the strands therein, the grooves being disposed such that the first and third grooves are spaced from the second groove by substantially equal distances on opposite sides of the second groove, the apertures forming a passage through the bonded frame members, and the strands substantially encircling the passage and extending from the frame; and the search coil frame assembly made in accordance with the aforesaid method.
