NOTES

1.Subject to improvement or modification without notice.

2.In Search Mode, the 1236-X2 operates under two modes of discrimination. With the SILENCER off, it operates in a classic 2nd derivative discrimination mode that allows all pops, clicks and partial target responsestobeheardformaximumtargetinformation. With the SILENCER on, the 1236-X2 operates in 3rd derivative SILENCER mode. This is especially useful for eliminating noise in extremely trashy areas.

3.The Search Mode has a 416 Hz target response. The

Pinpoint Mode has a Voltage Controlled Oscillator (VCO) target response that responds to the precise location of a target with increasing volume and pitch.

4.A slight audio threshold is provided in Search Mode when the SENSITIVITY control is set to its maximum setting. This aids in detecting the faintest of target signals.

5.Approximate.

6.Electro-Static-Insulated to eliminate certain types of false signals.

7.The transmitter frequency is centered nominally at 5.7 KHz and is user adjustable from 5KHz to 5.9 KHz to eliminate interference from nearby detectors.

ABOUT YOUR DETECTOR

Your 1236-X2 was designed to do one thing well, provide all the quality tools necessary to help you find good, deep targets in trashy or mineralized soil with minimum hassle. The 1236-X2 does this by providing you a wealth of powerfully, well designed

instrument controls and features that give you maximum flexibility of adjustment to accommodate your unique style of detecting. These are the controls on your 1236-X2 .

Sensitivity Control: Along with an increase in sensitivity to find those deeply buried targets, we’ve provided a versatile SENSITIVITY control to adjust the sensitivity when searching near large metallic objects or extremely trashy areas. At the

maximum SENSITIVITY setting a slight amount of audio threshold is provided so the faintest of target signals can be heard.

Dual Mode Discrimination: The 1236-X2 provides two powerful modes of discrimination for you to choose as you hunt in different environments. In both discrimination modes you can adjust the DISC control to accept certain types of metallic targets while simultaneously rejecting ground minerals, trash, and other less conductive metallic targets. With the SILENCER switch “off” the 1236-X2 operates in a classic 2nd derivative discrimination mode that allows all pops, clicks, and partial target responses to be heard for maximum target information. With the SILENCER switch “on” the 1236-X2 operates in a newly developed 3rd derivative SILENCER mode, eliminating all pops, clicks, and partial target responses for a quieter mode of operation. This mode of discrimination is especially useful for eliminating excessive pops and clicks heard when searching in extremely trashy areas.

ABOUT YOUR DETECTOR

Search Mode Motion Circuitry: In this mode of operation the motion circuitry in the 1236-X2 responds with a 416 Hz tone as the search coil is moved over a target. This makes the 1236-X2 less sensitive to soil mineralization and false target responses associated with the temperature drift and aging of electronic components.

No-Motion Pinpoint Mode With VCO Audio: At the push of a button, the all-metal no-motion pinpoint mode kicks in with

VCO (Voltage Controlled Oscillator) audio response for precise target locating. A located target responds with increasing volume and pitch. The tone gets louder and higher, so there’s virtually no doubt when you’re directly over a target.

VOLUME Control: For an extra measure of versatility, we’ve included a VOLUME control so you can set the audio level to suit your needs. You’ll no longer have to buy a special headset with extra controls to adjust the audio level.

FREQUENCY Control: You can vary the transmit frequency of your 1236-X2 from 5.5 KHz to 5.9 KHz. This control allows you to eliminate electrical interference from nearby metal detectors. A must for competition hunting.

User Setpoints And Factory Presets: The SENSITIVITY, VOLUME, FREQUENCY, and DISC controls all have recommended user setpoints that are indicated by a red-colored number on each control’s number dial. These setpoints provide a useful starting point for the new user. In addition, we’ve included a convenient factory preset IRON discrimination setting. When the DISC control is fully rotated counterclockwise to the IRON position, the 1236-X2 is set to reject common iron trash and nails.

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 swimming areas. New Corps lakes and lands must be okayed by the main office of the Army Corps of Engineers. Each area has a district office.

State Parks and Lands—Some state parks are open to metal detecting, but some are not. Always check with the park ranger before attempting to use your detector.

Bureau of Land Management (BLM) Lands—Some areas are open for metal detecting, and some are not. Always check with the district office.

City or County Park Lands—Most are open to metal detecting unless notice is given by a sign or city ordinance. When in doubt, always check with the city’s Parks and Recreation Department.

Public School Grounds—Most are open to metal detecting unless notice is given by a sign, city ordinance, law enforcement official, or school employee. You should always check with the school office first.

Privately Owned Lands (Private Property)—Permission required. And it is always best to have the permission in writing. Historically Marked Lands or Sites—Metal detecting is not allowed. Don’t even think about it.

ABOUT YOUR DETECTOR

Battery Test: A convenient battery test switch has been incorporated into your 1236-X2 to check the relative strength of the batteries. Rotating the SENSITIVITY control counterclockwise to the “BATTERY” position causes the 1236-X2 to give off an audio tone with the intensity indicating the strength of the battery. A low or absent audio tone indicates a weak or dead battery.

Built with the latest high-tech digital and analog surface mount circuitry, it all adds up to one great state-of-the-art metal detector with loads of versatile features. Treat it as you would any fine instrument and you’ll be rewarded with years of quality service and who knows how many treasures. If you have any questions, suggestions, or interesting 1236-X2 stories, drop us a line. In the meantime...

Happy Hunting!
