Chapter 5 DFX Pro Options ™ (Audio section) 5. Modulation Allows motion modes to produce different volume levels based on target depth. Modulation is used in the discriminate or motion modes. When ON, it allows the depth of the target to dictate the volume of the response.

Chapter 5 DFX Pro Options ™ (Discrimination section) 17. Recovery Speed Speeds target responses, so several targets that are close together can each respond. When a metal is detected, it takes a fraction of a second for the detector to process the signal before it can respond to another metal target nearby.
Chapter 5 DFX Pro Options ™ (Discrimination section) 18. Bottlecap Reject Adjusts how strongly the instrument rejects or breaks up on iron. Most starting programs use the minimum setting. As larger numbers are selected, more bias rejection against iron occurs.
Chapter 5 DFX Pro Options ™ (Discrimination section) 19. Hot Rock Reject Hot rocks (rocks higher or different in mineraliza- tion than the surrounding ground) respond as +95 on the V.D.I. scale. Unfortunately in some ground conditions very deep, small, or unusual real metal targets may also indicate +95.
