Description: TX850 Professional Waterproof Metal Detector Underground Scanner Search Finder Gold Detector Treasure Hunter Pinpointer The New TX-850 is unique among gold prospecting metal detectors for its combination of high sensitivity to small gold nuggets and its versatile function as an all purpose treasure detector.The controls and features are tailored to gold prospecting, including a sophisticated ground balancing system, separate control over signal gain and threshold,and aunique discrimination control system. These features also make for agreatrelic hunting detector. While theTX-850 makes fora highly competentcoin-shootingdetector,its user interface and features are not specifically designed for this purpose. As a coin-shooter,you will notice that the TX-850 exhibits slightly lower sensitivity to high-conductivity coins, like a U.S. quarter; this is a resul to fits specialized design to empha-size sensitivity to small, low conductivity metals like gold nuggets.

Walk around the target in a circle.2.While circling the target, continue sweeping the search coil across the target.3.Sweep once every 30° or 40° of the circle.If the tone does not change and the Target-ID value is consistent as you circle the target, you can be highly confident of the target’s identification.If the tone or Target-ID changes as you circle the target, you may have multiple targets or an irregularly shaped object.If the tone completely disappears at different angles, the target may be trash or a low- value metal.If you are new to the hobby, dig all targets. With practice in the field, you will soon be able to correlate audible and visual target feedback with certain types of metal objects. Pinpointing in Discrimination Mode:1. Sweep over target in narrowing side-to-side pattern.2. Take visual note of spot on ground where “beep” occurs.3. Step 90° to the side of the target.4. Sweep search coil over same area, at 90° to 1st sweep pattern.5. This pinpoints the target location with an “X.” TARGET PINPOINTINGAfter you have identified a target using Discrimination Mode, press-and-hold the PINPOINT button to identify the target’s exact location. This technique can yield more information about the target’s shape and size and also find its exact location to facilitate extraction.Pinpoint as follows:1. Position the search coil just barely off the ground, and to the side of the target.2. Now move the search coil slowly across the target; you can locate it by the sound. The target is located directly under where the sound is loudest.Narrow It Down:1. Tonarrow the response further, position the center of the search coil near the center of the response pattern, but not directly over thecenter.2. Release the PINPOINT button.3. Press-and-hold PINPOINT button again.4. Repeat this narrowing procedure to narrow the field of detection further.Note: Depth indication is less accurate after narrowing. NOTE: If you do not have prior experience with a metal detector, we strongly recommend that you:1): Adjust the Gain to a low setting in the event of false signals.2): Do not use indoors.This detector is for outdoor use only.Many household appliances emit electromagnetic energy, which can interfere with the detector. If conducting an indoor demonstration, turn the Gain down and keep the search coil away from appliances such as computers, televisions and microwave ovens. If your detector beeps erratically, turn off appliances and lights.Also keep the search coil away from objects containing metal, such as floors and walls.3): Use a 9-volt ALKALINE battery only. Do not use Heavy Duty Batteries.Item InformationColorBlackStretch Length42-52 incheBattery1*9V battery (not included)Working Voltage9VBasic SensitivityU.S coin (15 inch)Detect DepthMax: 2.5 meters (50*50*1.2cm Aluminium Board)Search Coil11-inch DD, waterproofFrequency19KHz, crystal controlIndication ModesLCD and Sound Indicator1Package Weight2.6kgNet Weight1.4kgFeatureEarphone Jack, Volume and Sensitivity AdjustmentGround Balance RangeFrom ferrite to sait water inclusiveBattery LiftUp to 15 hoursOperating Temperature(-10 to +50) Degree CelsiusOperating Humidiy Range0 to 90% noncondensingPortsAudio Jack
