ABOUT YOUR DETECTOR 1 The 1266-X was designed to excel in three ways: depth, discrimination and simplicity. It offers a better combination of these three characteristics than any other metal detector we’ve ever built. And we’ve been building metal detectors since 1931. Depth. Engineered to go deep in mineralized soil at high levels of discrimin ...

2 CONDENSED OPERATING INSTRUCTIONS The 1266-X is basically a turn-on-and-go metal detector. It doesn’t take an engineer to operate it but you’ll have more fun and a better chance of making that BIG find if you have a complete understanding of what you’re doing. That’s why we strongly recommend that you read the entire manual. But if you jus ...

3 SETTING UP Your 1266-X is just about ready to use. The only adjustment required is the angle of the search coil and the length of the stem. Take a look at Figure 1 and familiarize yourself with the parts of the 1266-X before proceeding. 1. Unpack it carefully. You may want to save the carton and inserts for future storage or shipment. 2. Depress ...

4 SETTING UP REMEMBER • THE LONGER THE SHAFT, THE MORE YOU WILL HAVE TO BEND YOUR ELBOW AND THE SOONER YOUR ARM WILL GET TIRED. THE 1266-X IS BALANCED FOR COMFORTABLE SEARCHING IN A TIGHT SEMICIRCLE AROUND THE FRONT OF THE OPERATOR. 6. With the stem length properly adjusted, tighten the lock nut and search coil wing nut. CAUTION: Never use a plie ...

5 1. DISC 1: DISCRIMINATE 1 is the search mode. The 1266-X automatically operates in DISC 1 unless the TRIGGER-SWITCH is pushed and held or pulled and held. DISC 1 is a full range discrimination mode. All types of metal are detected at the zero level and most small pieces of trash are rejected at the maximum level of ten. 2. DISC 2: DISCRIMINATE 2 ...

or weak batteries will give no tone. Batteries do not have to be replaced as long as you can hear a tone. As a general rule, you’ll be able to operate your 1266-X for an hour or two after the tone goes silent. 6. OFF/VOL: Power on-off and volume control. This control turns the power off at the full counter clockwise position and adjusts volume to ...

Turn the OFF/VOL control full clockwise. (If you’re wearing headphones reduce the volume to a comfortable level when the search coil is over a large target). 4. Set DISC 1 and DISC 2 at ...

8 others. You have now determined the approximate discrimination points for the rejected objects. For example, the small nail discrimination point may be 4 and the pull-tab discrimination point 6. 7. Push and hold the TRIGGER-SWITCH. The 1266-X is now operating in the DISC 2 mode. 8. Repeat steps 5 and 6 and you will note that the DISC 2 discrimina ...

9 Take a look at the illustration above and note how the discrimination level (as well as sweep speed and ground mineralization) affects the search coil detection pattern. Not only is depth reduced at high discrimination levels but also the width of the pattern is reduced. This change in width has a very important implication: if you’re searching ...

10 electrical interference caused by radio/TV stations, power lines, etc. Turn your sensitivity up if you want those deepest, smallest targets and you’re willing to put up with some background noise and more false signals. The maximum sensitivity position is with the knob pushed in and rotated full clockwise. 2. Decide how much discrimination you ...

11 Figure 6. Keep the search coil parallel and as close to the ground at all times. important for maximum coverage and depth. 4. If you’re hunting on a lawn you can set the coil right on the grass and search. 5. Take your time and overlap your sweeps by at least 50%. 6. Search in a methodical manner. Pay close attention to where you’re going an ...

12 ZERO MOTION PINPOINTING MODE Target location is a snap using the Zero-Motion Pinpointing mode. You do not have to keep the coil moving to get a response in this mode. 1. Once the presence of a buried target is indicated by the “beep-beep” of the 1266-X, simply place the coil LIGHTLY on the ground, away from the target area. Pull the TRIGGER- ...

13 TARGET RECOVERY Once you have pinpointed a target, your objective is to recover it quickly and neatly, leaving virtually 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 lo ...

14 OPERATING TIPS 1. We’ve already said it but it bears repeating: TAKE YOUR TIME AND OVERLAP YOUR SWEEPS. 2. Keep your discrimination levels set low. You’ll dig more trash but you’ll find more good targets, too. If you continually run at the pull-tab discrimination level you’ll find coins and silver rings but very few gold rings for exampl ...

15 ground mineralization, the higher the sensitivity loss. For example, you may be able to detect a penny 6 inches deep at zero discrimination, but no deeper than 4 inches at the pull tab discrimination point. Also, ground mineralization can reduce a detector’s ability to discriminate accurately. In highly mineralized soil, some trash targets may ...

16 FALSE SIGNALS Due to the extreme sensitivity of the 1266-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 1266-X does a good job of rejecting junk but it is so sensitive that “hot” mineralized spots in the soil, large, can fool it pieces of ...

17 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, smooth ...

18 BATTERY RECHARGING Rechargeable nicad batteries may take as many as 1,000 recharges, however they do have some limitations you should be aware of: 1. Nicads will last only about half as long as standard carbon-zinc batteries before recharging is required. 2. Nicads may develop a “memory” if you give them repeated “booster” charges. In ot ...

19 batteries will eventually only hold a three-hour charge. 3. Nicads may reverse polarity if discharged too far and will not recharge. Don’t leave your detector on and don’t continue to operate it more than an hour after the battery check tone goes silent. The optional 1266-X recharge kit includes (2) battery packs, (8) nicad batteries, (1) 11 ...

20 MAINTENANCE Your 1266-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 a while, 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 ...
