TIP$ & TROUBLE$HOOTING GUIDE
The new Coin$trike utilizes state
of the art D.P.A. technology that
sounds and acts like no metal
detector before it. One must
set aside what you know
about your old units and
look toward the future! The
following suggestive guide
is a work in progress for
all of us, as everyday new
tips and quirks are dis-
covered. Long time Fisher
users may find that they
take longer to adapt to the
sights, sounds, and capa-
bilities of the Coin$trike.
However, as with any new
detector, patience, long
hours in the field, and a
willingness to experiment with settings are
the keys to $uccess.

• Analyze Targets From All Angles -
This is the best overall rule of thumb to follow, as initial sweeps may indicate a positive
reading on deep iron or hot rocks. The center-of-the-coil vs. target relationship can cause
the numbers to “jump”, so use a slower sweep from different directions. In some instances,
removing some soil can result in a better ID (and a negative reading for iron objects).
• Diggin’ On Day One -
Don’t be afraid to recover some negative or “jumpy” objects at first. This helps
in the process of learning what information the Coin$trike is offering. Confi-
dence and success will grow after several hours use and when in doubt, DIG!
• Low & Slow -
A huge cause of new user frustration centers around running the Threshold
and/or Sensitivity too high for fear of depth loss. Try a Threshold setting of
–20 or -30 combined with a Sensitivity setting below 5 as a better starting point.
• Take Your time -
The Coin$trike operates best with a moderate sweep speed and by overlapping your sweeps.
Fast “whipping” not only misses items, but can create poor ID’s or “falsing”.
• Auto Ground Balancing -
This is extremely important to the Coin$trike set-up. Be totally certain to balance on an area
totally void of metal. Holding the P/P (pinpoint) pad can assist in locating a “clean” spot.
Ground balancing in All Metal can also help, as the bobbing of the coil up & down without noise
indicates proper balance. Also, be sure to re-balance after changing modes and/or settings.
• Raise the Coil -
Shallow or large objects can prompt overloads or poor target ID. Lifting the coil up a couple
inches can help determine size, depth, and may even help to drop unwanted trash down several
ID digits. Raise the coil above overloads to be certain of not passing over shallow “goodies”.
• Use Your Features -
In some environments, such as those with heavy mineralization, keeping the Averaging (A1)
and Auto Track functions ON can help stabilize the Coin$trike for smoother operation.
When the Averaging function is OFF (A0), the Coin$trike produces a “real-time” numeric
output, which may cause target ID’s to appear “jumpy” in these conditions. Again, experiment to find suitable settings for each site.
• 99 is Fine -
The old theory that running iron disc maxed out at 99 takes away from depth
is untrue with the Coin$trike. With iron disc at 99, the Coin$trike nulls most
iron, and users should not be hesitant to use this setting in most conditions.
• Utilize Memory Banks -
Save your favorite settings to be ready for different environments. For example,
MEM 1 can be your “lower level” choice to bring up on a trashy site. MEM 2 may
then be your “hotter” (high Sens/Thresh) settings for better soils, or relic hunting.
• Tone Trouble?
The 4 higher-pitched tones can, at first, sound quite confusing (especially in trash). Detectorists stepping up from a one-tone unit should not get frustrated. Instead, choose a cleaner
(less-trashy) site, and when in doubt, just concentrate more on the LCD reading. It may take
hours to “learn” all the sounds of the Coin$trike.
• All Metal Quick Check -
Toggling into the very sensitive All Metal mode often rewards the user with a more solid ID
number (positive or negative) on jumpy, small, or deep items. Conversely, a relic hunter using the
All Metal mode may choose to do the opposite, and check a target by switching into disc mode.
• De-tune Pinpointing -
Although many hunters like to “de-tune” with the P/P (pinpoint) pad to further compress
the target signal, use caution; too much de-tuning may silence the item on the Coin$trike
completely.
• Fast Pinpoint -
Although the pinpointing number system gives accurate info for target depth, size,
and shape, one does not necessarily have to hold down the PP touch pad for competition-style pinpointing. With practice, listening for an increasing tone while
using a cross-over, X-style sweep produces decent results when speed counts.
• Positive Threshold -
Getting as deep as possible in the Disc mode may require becoming accustomed to hearing
a threshold hum (0 to +1 threshold) and/or running sensitivity as high as the soil permits.
Remember that tracking may need to be off with these settings. The All Metal mode also
offers superior depth, but the user must rely on the numeric ID for target information.
• Choosing a Coil -
Examine the situations you will encounter in the field to determine the best size, as there
are advantages to both. The 10.5 inch coil can provide more depth, and a better “lock-on”
ID for those smaller, weaker signals mentioned above. It’s added weight can be eased with
body mounting. The 8 inch standard spider coil helps to utilize the Coin$trike’s strength
of unmasking “good” items from heavy trash and is a fine, light weight, all-around choice.
• Notching Screw Caps -
Always a problem with ID detectors, because they often show up in the coin range. Notching
ZINC may eliminate some, but risks the loss of good targets in that range, such as some
gold.
• 6 Volts -
Weak batteries can affect productivity, so try to avoid running them all the way down to the
wavering tone alert. Have new batteries on hand, and install them when you see 6V on the
LCD during turn-ON.
• Collect Troublesome Targets -
Keep those screw caps, iron rings, and other items that may have “fooled” you. Bring them
home and experiment with notch disc settings, raising the coil, etc… to find possible remedies.
T R O U B L E $ H O O T I N G
As mentioned earlier, Coin$trike problems often center around the settings of thresh-
old, sensitivity, and auto-ground balancing. Poor set-up, even in one of these 3 areas,
combined with hostile outside conditions (such as bad soil, power lines, and ground balancing too close to metal objects,…) may set the user up for frustration. The following
“troubleshooting” section may be useful to those experiencing questions or difficulties.
• Possible Sources of Erratic Numbers/ Falsing:
• Threshold/ Sensitivity too high (try Thresh @ –20 or -30 & Sens @ 4 or less)
• High mineralization/black sand (again, lower Threshold & Sensitivity)
• Poor Ground Balance
• Tracking and/or Averaging OFF
• Fast, whipping sweep speeds and/or hard “scrubbing” of coil
• Outside electronic interference/Power lines (again, lower Threshold & Sensitivity)
• FP (factory preset) mode with 0 threshold (lower Thresh to –20 or less)
• Is the coil cord plugged all the way into the housing and hand tight?
• Is the cord wrapped neatly around the rods using 3 Velcro straps provided?
(loose cord = falsing)
• Magnetized soil particles lodged in between coil and coil cover?
T R O U B L E $ H O O T I N G
• Max Sensitivity:
Treasure hunters may believe that they must run sensitivity on 10 (or Max), or they will lose
many inches. On the contrary, with the Coin$trike, setting sensitivity too high can lead to
accuracy problems.
Remember: Great effective depth can be achieved with lowered settings.
• How Can ID’s Be Different?
The exact same item (such as a coin) will not always be the same number,
but it will remain favorable (“diggable”) in the positive ID range. Many factors, such as target position in the soil (coins on edge), coil position, ha-
los, nearby trash, and different depths contribute to the ID number generated.
• Factory Preset Threshold:
The saved FP mode can be a good starting point for, as the manual says, “coins only” hunting.
However, some mineralized locations report stability problems or chatter with the Threshold
preset of 0. Again, start slow with say a -20 threshold for a more silent search. Once familiar
with the unit (and if soil permits), you can begin your climb back toward the 0 threshold level.
• Is Averaging ON or OFF?
Be careful when attempting to activate A1. Hold the All Metal/Disc touch pad, and when A1
appears on the display, release it. Holding the touch pad too long will advance it to A0 again,
which deactivates this feature.
• Powerlines/ Outside Interference:
All detectors suffer in these areas, and the sensitive Coin$trike is no different. Once more,
adjusting the threshold to -20 or less makes these situations “huntable”. Sensitivity may also
be lowered if necessary.
• Salt Mode/Beaches:
Although many would assume the salt mode should always be ON (S1) at the beach, in magnetized or wet black sands of some beaches, better performance can be attained with Salt
OFF (S0) and a negative threshold setting. Salt mode OFF also seems to be more conducive
to small items of gold as well. For beaches with little or no black sand, set S1 before balancing and adjusting threshold & sensitivity. Tracking and Averaging ON can be helpful for
beach stability as well.
• Hot Rocks:
Some parts of the country report black, hot rocks falling into “good” target ranges (examples: 02, 06, 12, & 51). But, just like iron that may read “good” on the initial swing, further
analysis of sweeps from different angles should cancel these hot rocks completely. Large,
and or, shallow hot rocks may “fool” you into recovery.
• Area #51:
Seeing #51 show up often? Though this does appear on the unit in the possible “high, silver coin” range, as mentioned above, various “hot rocks” and other false signals may ID as
#51. Solution: only dig #51 if it repeats from other angles.
• Coil Cover Drawback:
Though recommended as protection for those who “scrub” the ground, use caution as the ultra-sensitive Coin$trike can become very erratic when magnetized particles slip in between the
cover and coil. Beaches can be most troublesome, as black sands can build up inside quickly. TIP:
Coil cover users can fill the cracks with a type of silicone sealant to keep the mineralized soil out.
• Light Leaks?
Users have questioned a trace of light from the side of the LCD while hunting at night using the back light. This is normal, and due to the clear
plastic panel of the Coin$trike. Your unit is still dust & splashproof.
