Read this instruction manual from cover to cover and treat your 1212-X as you would any high quality precision instrument. Drop us a line if you have any questions, comments, or exciting 1212-X stories. In the meantime . . .
SETTING UP The 1212-X comes to you just about ready to use. The only adjustment required is the angle of the stem. Take a look at page 3 and familiarize yourself with the parts of the 1212-X before proceeding. 1. Unpack your new 1212-X carefully. Save the carton and inserts—they may come in handy for...

CAUTION: Since the 1212-X has a fixed volume setting (loud), always use headphones with individual volume controls adjusted to a comfortable level. Also, If you use a stereo headphone, make sure the stereo/mono switch is in the “stereo”...
Typical 1212-X audio responses over 1 inch deep targets with search coil sweeping 2 to 3 inches above ground. Note that the terms “discrimination” and “trash rejection” are used interchangeably.

NOTE: The discriination levels shown are typical values only and may vary from detector to detector. Figure 4. Typical 1212-X audio responses over 1-inch deep targets with search coil sweeping 2 to 3 inches above ground.
In relatively non-trashy soil you may wish to search at zero trash rejection. In this manner, your 1212-X is at its most sensitive and will detect all metal targets within its range. Once an object is detected, you can increase the trash rejection level for further identification.

Other motion detectors may require a fast sweep speed for maximum sensitivity. If you try that with your 1212-X, you’ll actually lose sensitivity. When the stem length is properly adjusted, the 1212-X is balanced for sweeping in a tight semicircle. Always overlap your sweeps at least 50%.
PINPOINTING Pinpointing takes practice. The more time you spend with your 1212-X the faster and more accurate you’ll become. 1. Once a buried target is indicated by the tell- tale “beep” of the 1212-X, continue moving the search coil from side-to-side across the target in a narrower and narrower search pattern.

Generally speaking, beachcombers do little if any damage to the environment while recovering targets. However, if you plan to use your 1212-X on lawns or in parks, your target recovery method can be very important. Two of the most successful methods are illustrated in a separate booklet enclosed with your 1212-X.
6. When in doubt about the possible identity of a target, dig it up. 7. The 1212-X is an easy detector to use but if you’re having trouble with any aspect of its operation (pinpointing, searching false sig- nals, etc.) go back and reread the part of this manual relating to your problem.
FALSE SIGNALS Due to the sensitivity of the 1212-X, you’re bound to get some “false signals” once in awhile. A false signal occurs when something that shouldn’t sounds like a good target. The 1212-X does a good job of rejecting junk but it can be fooled by “hot” mineralized spots in the soil, large pieces of junk, some kinds of bottle caps and pull tabs or trash less than 2 inches from the coil.
6. DIGGING TOOL: If you’re carrying a metal sand scoop, digging knife or screwdriver, hold it behind your back or keep it above your waist. Your 1212-X is sensitive enough (depending on how big the digging tool and how low you hold it) to sound off each time you sweep your search coil beneath it.
MAINTENANCE Your 1212-X doesn’t require a lot of care but there are a few things you should do to keep it in peak operating condition. 1. If you’re not going to be using it for awhile, take the batteries out. Acid damage caused by a leaking battery can be severe.
Where To Use Your Metal Detector In The National Forest and Federal Lands—Metal detecting is allowed only by special permit acquired from the federal government. Each area has a district office. Corps of Engineers, Lakes, Shorelines and Lands—Permission has been granted only on predisturbed sites, such as beaches and attached swimming areas.
3. Pulsegate Unipolar Audio Processing. Advanced Fisher circuitry which allows silent operation below “audio threshold tone” with no loss in sensitivity. 4. The 1212-X is a “motion” detector while in the search mode. The search coil must be moving at least slightly to detect a target.
