SEARCH TECHNIQUES
Target Verification
After detecting a target, do the following:
1. Walk around the target in acircle.
2.While circling the target, conttinue 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- valuemetal.
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. Takevisual note of spot on ground where “beep” occurs.
3. Step 90° to the side of the target.
4. Sweep searchcoil over same area, at 90° to 1st sweep pattern.
5. This pinpoints the target location with an “X.”
TARGET PINPOINTING
After 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 searchcoil just barely off the ground, and to the sideof the target.
2. Now move the searchcoil 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 searchcoil
near the center of the response pattern, but not directly over the
center.
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.
The MD-6450 includes exclusive Target ID technology and patented discrimination features. This technology features two indicator scales that allow you to see the detector’s discrimination setting (Lower Scale) as well as the analysis of each detected target (Upper Scale)
The MD-6450 also featuresEnhanced Iron Resolution (additional resolution for separating desirable targets from iron junk in cluttered areas) and a standard 8.5" × 11" elliptical Double-D searchcoil engineered for optimum performance in more challenging mineralized soils.
MD-6350 metal detector is the most advanced of its kind in the industry.Whether you are experienced or a beginner, this machine is well suited for a widevariety of your detecting environments. With One-Touch operation, the MD-6450 powers on with the touch of a single button, adjusts easily for groundminerals and is immediately ready to begin searching.

Features
Mode—Indicates which of the five detection modes (Zero, Jewelry, Custom,Relics or Coins) has been selected by highlighting the corresponding word on the LCD screen.
Target ID Legend—Works in conjunction with the Target ID Cursor to
indicate a target's probable identity.
Target ID Cursor (Upper Scale)—The Target ID cursor, in conjunction withthe Target ID Legend, indicates the probable identity of a detected target. Theupper scale consists of twelve (12) graphic segments for Target ID.
Lower Scale—The lower scale, or Notch Discrimination Scale, indicates the discrimination pattern. The MD-6350 will produce an audible target response for the pixels that are switched on, and no audible response for those thathave been switched off. The Target ID Cursor will always indicate all targets.The discrimination pattern can be adjusted by changing modes and / orusing the DISCRIM and Accept/Reject (√/×) pushbuttons (see page 13).
Coin Depth Indicator—The depth of a coin, or similar sized target, is indicated in 2-inch incrementsBattery Level Indicator—Indicates the current battery condition.
You can expect 20 to 40 hours of operation depending on battery type andquality.Access and replace the batteries by sliding the cover off the control housing. Remove batteries when the MD-6350 will be stored for longer than 30 days.
Sensitivity Indicator—The MD-6450 has eight (8) settings for sensitivity.
