ABOUT YOUR DETECTOR Your 1225 -X was designed to do one thing well: find good, deep tar get s in tr ash y or mi ner ali zed soil with a mini mal amou nt of hass le. Here’s how it does it... VLF-SLOW MOTION DISCRIMINATION . In the sear ch mode, your 1225-X will simultaneously ignore minerals and trash as it detects valuable targets. Unlike earlie[...]

2 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.[...]

4 CONTROL FUNCTIONS 1. D ISC: This control turns the power on and auto mat ical ly tune s the 1225 -X for ins tant opera tion . All types of metal are detected at the zero level while the most pieces of trash are rejected at ten. The DISC control has no effect when the PINPOINT button is pushed in. 2. SENS: Normally set at ten, this control adjusts[...]

5 By adjusting the DISC (“Discrimination”) control, you will be able to ignore or (“reject”) small pieces of metallic target trash a n d g r o un d m i n e ra l s w h i l e d e t e c ti n g v a l u ab l e t a r g et s . T h e lowest setting at which an object is rejected is reffered to as its “discrimination point.” Discrimination point[...]

8. Some objects will cause sharp static or “ticking” when rejected. This is a perfectly normal response indicating that the powerful discrimination circuitry of the 1225-X is doing the job. 9. Large pieces of trash such as beer cans or jar lids may sound like a good target no matter what you do. With a little practice however, you will be able [...]

Now comes the fun part - if you follow a few simple rules. Good search techniques are every bit as important as a good detector. 1. Th e 12 25 -X ha s tw o ope ra ti n g mod es . The “S ea r ch ” mode is activated simply be turning the unit on. This is a “VLF-Motion Discrimination” mode which automatically ignores most ground minerals, reje[...]

8 SEARCHING 7. Search in a methodical manner sweeping in a tight semicircle. Pay close attention to where you’re going and where you’ve been. 8. TAKE YOUR TIME. If you walk too fast you can’t o v e r l a p y o u r s w e e p s a n d y o u ’ l l m i s s a l o t o f ground. If you sweep too fast, you’ll lose sensitivity and miss the faint to[...]

9 ZERO MOTION PINPOINT MODE The pinpoint mode requires no tuning, no motion, detects all metals and in normal soil it’s even more sensitive than the search mode. Precise target location is a snap. 1. Once the presence of a buried target is identified by the “beep beep” of the 1225-X, simply place the coil lightly on the ground away from the [...]

10 PINPOINTING IN MOTION SEARCH MODE Pinpointing in the search mode will take a little practice but you may find that for most targets, it’s even quicker than the Zero Motion Pinpointing Mode. Simply use the same procedure as in steps 2 through 5 above. The only difference will be that when you stop the coil over the target you will lose the aud[...]

11 Once you have pinpointed a target, your objective is to recover it quickly and neatly, leaving no trace of your excavation. There are almost as many ways to do this as there are Treasure Hunters. Whatever works for you is good enough as long as you don’t break any laws, damage vegetation, or leave your search area looking like a World War II b[...]

12 RECOVERY TOOLS 1. A heavy duty, blunt screwd river is common ly used by expert Treasure Hunters. 2. A s tu rd y hun ti ng kn if e wi th a 5” bl a de wi ll do th e job in most soils. A high quality double-edged “survival” knife is an even better (and more expensiv e) choice since it will be almost impossible to bend or break. CAUTION: Using[...]

13 OPERATING TIPS 1. We’ve already said it but it bears repeating: TAKE YOUR TIME AND OVERLAP YOUR SWEEPS. 2. U s e g o o d h e a d ph o n es . Y o u w o n ’t m i ss f a i nt targets, you won’t attract unwanted attention and you won’t bother others. 3. Practi ce pinpointing. There’s nothing sacred about the methods described in this manua[...]

14 A “false signal” occurs when something that shouldn’t, sounds like a good target. Your 1225-X does an excellent job of ignoring junk but it’s so sensitive to good targets that it can be fooled by bad targets with similar electrical characteristics. Large pieces of trash for example, or even some kind of bottle caps and pull tabs. Small p[...]

15 between the beeps, or if you sweep at right angles to your original direction, you’ll receive a single beep directly over the target (except for the very shallow coin). One way to tell the difference between a coin and a nail is to set your discrimination at about 5. Most small nails will be tuned out while most coins will respond with a good,[...]

16 BATTERY REPLACEMENT Two nine volt transistor batteries are located in separate com pa rtm en ts at the rear of the hou sin g. When it’ s tim e to repl ac e batteries, always replace both of them. 1. To op en , pr es s ge nt ly dow n an d ou t on the bat te ry door latch. The doors are hinged, do not attempt to completely remove them. 2. Tilt t[...]

17 MAINTENANCE Your 1225-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 leaking batteries can be severe. 2. Avoid extreme temperatures like the inside of a closed car sitting in the s[...]

18 Where To Use Your Metal Detector In The U.S. 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 swimmin[...]
