Page 3: About Your 1280-X
Fisher Research Laboratory has been producing rugged, high quality, high performance metal detectors since 1931, longer than any other company in the world. Your 1280-X Aquanaut is a product of that proud heritage. Designed for deep sea treasure hunting, the 1280-X will also do the job in fresh water or on land. -

ASSEMBLY Battery Access Panel 8-inch Spider Coil Control Panel Derlin Screw and Nylon Wing Nut LED (Light Emitting Diode) Lower Stem Upper Stem Search Coil Cable Adjustable Arm Rest Waterproof Headphones Arm Rest Screws Spring Lock (Not visible) The 1280-X requires very little assembly. Unpack it carefully and save the carton which may come in handy for future storage or shipment. -
Page 5: Setting Up
SETTING UP FOR LAND OR SHALLOW WATER (See Figure 2-A) Put the headphones around your neck to keep them out of the way while making the following adjustments. 1. Adjust the length and coil angle so that the search coil rests flat on the ground about 6 inches in front of and slightly to the right of your right foot (to the left of your left foot for left handers.) Your arm should be straight and relaxed with the handle... - Page 6 SETTING UP 3. You should now be able to move into your “search” position by leaning slightly forward and raising the search coil approximately 1 inch above the ground. Your arm should still be straight and the coil should be parallel to the ground, about 12 inches in front of your foot.

Page 7: Hipmounting
HIPMOUNTING For almost effortless treasure hunting, the control housing is easily removed from the handle and attached to a belt clip. “Hipmounting” the 1280-X in this manner takes half the weight off the handle and allows the land or shallow water Treasure Hunter to search much longer without arm fatigue. - Page 8 HIPMOUNTING 5. Slip the control housing onto your belt, left side for right handers, right side for left-handers. CAUTION: Hipmounting is not recommended for underwater use. The search coil cable may become entangled with a submerged object, making it difficult for the diver to resurface quickly in case of emergency.

CONTROL PANEL 1. POWER/VOLUME CONTROL: Turns the power on and off. Also controls the target response volume in the headphones. The volume control should be set no louder than comfortable when the search coil is passed over a large, close target. 2. -
Page 10: Discrimination Points
DISCRIMINATION POINTS By adjusting the DISCRIMINATION control you will be able to ignore (or “reject”) small pieces of metallic trash and ground minerals while detecting valuable targets. The lowest setting at which an object is rejected is referred to as the object’s “discrimination point”. - Page 11 DISCRIMINATION POINTS are rejected, however other objects may “snap, crackle and pop” as they are rejected. This is a perfectly normal response indicating that the powerful discrimination circuitry is doing its job. 9. Large pieces of trash such as beer cans or jar lids may sound like good targets no matter what you do.

Page 12: Searching
SEARCHING Good search techniques remain the same whether you’re using your 1280-X in the desert or on the bottom of the ocean. 1. Decide how much discrimination you want to use. a. In relatively non-trashy areas you may wish to search at zero discrimination. - Page 13 SEARCHING 1. Minimum Depth a. Very slow or fast sweep speed. b. Discrimination set at “10.” 2. Good Depth a. Moderate sweep speed. b. Discrimination set at “5.” 3. Maximum Depth a. Moderate sweep speed. b. Discrimination set at “0.” 4.

Page 14: Pinpointing
PINPOINTING Pinpointing takes practice. The more time you spend with your 1280-X, the faster and more accurate you’ll become. 1. Once a buried target is indicated by the tell-tale “Beep” of the 1280-X, continue moving the search coil from side-to-side across the target in a narrower and narrower search pattern. -
Page 15: Target Recovery
TARGET RECOVERY Once you have pinpointed a target, your objective is to recover it quickly and neatly, leaving virtually no trace of your excavation. There are almost as many ways to do this as there are treasure hunters. Whatever works best for you is good enough as long as you don’t break any laws or leave your search area looking like a World War II Battlefield. - Page 16 TARGET RECOVERY up by inserting the screwdriver into the ground next to the hole and pulling in towards the center. Do this 4 to 5 times around the edge of the hole until it is no longer visible. PLUGGING METHOD This method of recovery is not allowed in many areas and should never be used in dry lawns or in very hot weather.

TARGET RECOVERY and around the hole. 8. Recheck the hole and the area around the hole with your 1280-X if you still can’t find it. 9. Once you have recovered the target, check the area again. Two or more coins are often found in the same spot. - Page 18 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.

Page 19: Operating Tips
OPERATING TIPS may be difficult to reject. The 1280-X will instead respond with a strong broken signal which will usually disappear if the coil is speeded up or raised slightly. 9. If you hear two beeps very close together and can’t find anything under either one, you’re probably over a nail or some other elonggated ferrous object. -
Page 20: Battery Replacement
BATTERY REPLACEMENT Eight 1.5V size AA batteries are located in the rear section of the Control Housing. The batteries are sealed off from the electronics so that accidental water leakage into the battery compartment will not damage the circuitry. 1. Remove the battery cover by partially unscrewing the two knurled thumb screws with a coin. - Page 21 BATTERY RECHARGING batteries will eventually only hold a three-hour charge. 3. Nicads may reverse polarity if discharged too far and will not recharge. Don’t leave your detector on and don’t continue to operate it more than an hour after the battery check tone goes silent.

Page 22: Maintenance
MAINTENANCE CLEANING Hose down your 1280-X with clean fresh water whenever you’ve had it on the beach or in the water. Pay particular attention to the following areas: 1. Stem adapter. Sand or dirt between the coil “ears” and stem adapter will literally grind away the ears and adapter. -
Page 23: Search Coils
SEARCH COILS The 1280-X is available with either the standard 8 inch “Spider” coil or the 10.5 inch “Spider” coil. As a general rule, the 8 inch coil is preferred for tight spots, fast moving surf and high density trash areas. For normal conditions however, the 10.5 inch coil will cover a little more ground with each sweep and will give slightly more depth 5 to 20 percent in air, less in soil, depending on target size and mineralization. -
