OPERATING TIPS

1. Keep the search coil cable wound snugly

around the stem when diving around coral or

jagged rocks to keep it from snagging.

2. Divers should make sure the drain holes in the

headset are unobstructed. Better yet, wait until

you’re on the bottom before putting them on and

take them off before surfacing.

3. Divers should also keep the search coil at least

two feet away from their body. Metal gear

(weights, gauges, tanks, etc.) will be detected by

the 1280-X if held too close.

4. Practice pinpointing. There’s nothing sacred

about the method described in this manual. Many

1280-X users have developed their own

pinpointing methods.

5. False signals may be caused by rapidly moving

surf, highly mineralized or trashy ground, large or

irregular shaped trash and bumping or raising the

search coil very fast. A false signal will generally

sound suspicious to the experienced treasure

hunter. It may be very faint, or very sharp and

abrupt with static. Often when you go back over

the same spot a false signal will simply disappear.

You may reduce the number of false signals you

get by increasing the discrimination level and/or

reducing the sensitivity level.

6. If you’re wading or hunting on land, hold your

digging tool behind your back or above your waist.

Your 1280-X is sensitive enough to sound off each

time you sweep your coil beneath it.

7. There is some sensitivity loss at the higher levels

of trash rejection. The greater the ground

mineralization, the higher the sensitivity loss. For

example, you may be able to detect a penny 6

inches deep at zero discrimination, but you may

be able to detect it no deeper than 5 inches at the

pull tab discrimination point.

8. Some objects such as shallow bottle caps, bent

pull tabs or trash less than 2 inches from the coil
