You can reverse this pinpointing technique to pinpoint off
the DD coil's tail; in this case, push the coil away from you.
The audio and LCD meter will place the target just off the
searchcoil's tail.
• Alternative pinpointing technique: DD-wiggle. Quickly
locate targets without using the Pinpoint button as follows.
Continuously swing the searchcoil side-to-side using fast,
narrow swings of 5–10cm (i.e. wiggle). While continuing
this side-to-side wiggle, slowly move the searchcoil sideways
toward the target's suspected position until the audio response
produces a consistent, symmetric beat. This indicates the
lateral left-to-right position of the target. Then locate the
target's front-to-back position by rotating around 90° and
repeating the same process.
Tip: Practice any or all of these various pinpointing options in
your test plot. Choose the technique that works best for you.
As you improve your pinpointing accuracy, you will dig smaller
holes and increase your productive hunting time.
