Pinpointing Solved
After reading the manual better and testing outside with some targets, I was able to better understand the pinpointing with the Bounty Hunter Platinum.
Using what the manual said about narrow it down helped a lot.

PINPOINT
To activate this mode, you must first be in the DISCRIMINATION mode.
Press and hold the pinpoint button to activate pinpoint. This mode is equivalent to ALL METALS, but is momentary; pinpoint detection is only active for as long as you keep the pinpoint button depressed. Pinpoint is used to find the exact location of a target which was previously located and identified using the discrimination mode. As this mode does not require motion over the target, the user can move the coil more slowly and then narrow the detection field when near the target.
How to Pinpoint
Position the searchcoil an inch or two (2.5-5cm) above the ground, and to
the side of the target. Then press and hold the pinpoint button. Now move the searchcoil slowly across the target, and the sound will communicate the
target’s location. As you sweep from side to side, and hear no sound at the
ends of the sweep, the target is located in the middle of that zone,
where the sound is loudest. If the sound is loud over a wide area, the
buried object is large. Use Pinpoint to trace an outline of such large objects.
Narrow It Down
To further narrow the field of detection, position the searchcoil
near the center of the response pattern (but not at the exact center),
release the pinpoint button , and then quickly press-and-hold it again. Now you will only hear a response when the searchcoil is right over the top of the target. Repeat this procedure to narrow the zone even further. Each
time you repeat the procedure, the field of detection will narrow further.
