2. Turn the headhunter pirate power on. Set volume to a desired level. This can be
accomplished by passing a coin back and forth under the search-coil.
3. Rotate the “SENS” clockwise till some solid sounding audio is heard.
4. Then rotate it counterclockwise a little till the audio signal is disappeared.
5. Set the “DISC” to ALL METAL position, in case it will reject some metal targets
you want.
6. Keep the search-coil be parallel with the ground,-and about 1/2 to 1 inch above the
surface. Sweep the search-coil in a side-to-side motion. When you find metal
targets, the metal detector will respond with “di-di” tone.( see Figure 5)
7. Slowly rotate “DISC” clockwise till “di-di” tone disappears, you may determine
the type of the metal targets.
8. By the following operation, you can pinpoint the location of the targets. First raise
the search-coil off the target, slowly sweep the search-coil until the unit sounds a
“di-di” tone. Then you pass 90 degrees, slowing sweep the search-coil, keep the
sweeping direction of this time in an opposing direction with the last time, you can
also hear a “di-di” tone. The intersection of the two “di-di” tones is the appropriate
position of the target.
9. Retrieving targets submerged in water is more difficult than on land. If you are
wading in the surf, make sure you use some kind of sand scoop. This will make
you easier to dig out the targets.
10. This ear-cup is O-ring sealed. Be sure to carefully clean the O-ring, lubricate
O-ring sparingly with silicone grease only. Do not use Vaseline.
11. Always thoroughly rinse your headhunter pirate in fresh water after using in salt
water. Store your detector in a dry and cool place.
