Here’s how it does it... VLF-SLOW MOTION DISCRIMINATION. In the search mode, your 1225-X will simultaneously ignore minerals and trash as it detects valuable targets. Unlike earlier motion discriminators, you won’t have to whip it back and forth but, you will have to keep it moving at least slightly. ZERO MOTION PINPOINTING. A push-button, all metal mode which requires no motion for fast, precise target location. Also referred to as “electronic pinpointing.” AUTOMATIC OPERATION. There’s no ground adjust control on your 1225-X. Just turn it on, set two knobs and go. It couldn’t be simpler. PULSEGATE UNIPOLAR AUDIO PROCESSING. Fisher engineering jargon meaning that you won’t have to listen to a “threshold tone” for maximum sensitivity. Your 1225-X operates so you can hear even the faintest signals on small deep targets. DOUBLE DERIVATIVE MOTION CIRCUITRY. Provides a target response as the search coil passes over the target. Earlier motion detectors responded AFTER the coil passed over the target. Protected by U.S. Patent 4,514,692. And of course, there’s more. Like the built in arm rest and detector stand. And, the drop-in, no-wires battery compartment. And, most importantly the depth! Your 1225-X goes deep. It all adds up to one great state of the art metal detector. Treat it as you would any fine instrument and you’ll be rewarded with years of service and who knows how many treasures.

Fisher Research Laboratory 1 SETTING UP The 1225-X comes to you just about ready to use. The only adjustment required is the angle of the search coil. Take a look at Figure 1 and familiarize yourself with the parts of the 1225-X before proceeding. 1. Unpack your new 1225-X carefully. Save the carton and inserts they may come in handy in the future for storage or shipment. 2. Slip the lower stem into the upper stem. 3. Adjust the stem length (using the locknut) and the coil angle (using the nylon wing nut) so that the search coil rests flat on the ground about 6 inches in front and slightly to the right of your right foot (to the left of your left of your left foot for left handers). Your arm should be straight and relaxed, the grip held loosely. REMEMBER: The longer the shaft, the more you will have to bend your elbow and the sooner your arm will get tired. The 1225-X is balanced for comfortable searching in a tight semicircle around the front of the operator. 4. With the stem length properly adjusted, wind the cable loosely around the upper and lower stems and connect the cable connector to the control housing. CAUTION: Make sure that the cable is not pulled tight at the control housing and that you have enough slack at the search coil to adjust it to any angle. 5. With the shaft length and coil angle properly adjusted, you should be able to move into your “search” position by leaning forward very slightly and raising your arm (still straight) until the search coil is about 1 inch above the ground and 12 inches in front of your foot. The search coil should be parallel to the ground and may have to be slightly readjusted at this point. 2 SETTING UP Battery Access (not shown) Waterproof Search Coil Search Coil Cable Cable Connector (not shown) Control Housing Hand Grip Cable Strain Relief Padded Arm Rest Lock Nut Nylon Wing Nut Adjustable Lower Stem Upper Stem Figure 1.
