Orbitor Prospector 100 Metal Detector Manual Site

The Orbitor Prospector 100 is a beginner-friendly metal detector designed for hobbyists looking for a straightforward, lightweight tool for land and shallow water exploration. This guide provides a comprehensive manual for setup, operation, and maintenance to help you maximize your treasure-hunting results. Core Features and Specifications

The Prospector 100 is built for ease of use, featuring controls that allow for both general searching and basic target filtering.

Operating Frequency: Typically operates around 6–7.8 kHz, a standard range for finding coins, relics, and jewelry.

Search Modes: Includes All-Metal (detects everything) and Discrimination (filters out junk like iron).

Search Coil: Usually features a waterproof coil allowing for use in wet grass or shallow puddles (though the control box is not waterproof).

Power Source: Most models require two 9V batteries or a rechargeable unit, offering approximately 8 hours of use. Quick Start Guide: Setup and Calibration Orbitor Prospector 100 Metal Detector Manual

Assembly: Extend the adjustable stem to a comfortable length and secure the search coil. Ensure the cable is wrapped loosely around the shaft to prevent signal interference or cable strain.

Power On: Turn the volume/power knob clockwise to activate the unit.

Sensitivity Adjustment: Set the sensitivity to the highest level possible without the detector "chirping" or becoming unstable. If you encounter mineralized soil or electrical interference, lower the sensitivity slightly.

Air Test: Before heading out, pass a coin or iron nail in front of the coil to hear the different audio tones. Operating Techniques Prospector 100 Metal Detector(958) - Alibaba.com

The Orbitor Prospector 100 is an entry-level, hobbyist metal detector featuring "All Metal" and "Discrimination" modes, a 7.4-inch waterproof coil, and 9V battery power. Designed for detecting precious metals, the unit operates best with a 1-2 inch ground clearance and can detect objects at depths of 6–8 inches.

The Orbitor Prospector 100 is an entry-level, lightweight metal detector designed for beginners, featuring adjustable discrimination modes and a waterproof search coil for shallow ground treasure hunting. The manual outlines simple, tool-free assembly and advises maintaining a "low and slow" sweep, with sensitivity adjustments to manage ground mineralization.

I couldn’t find a verified user manual for a model called “Orbitor Prospector 100” in major detector brands (Minelab, Garrett, Fisher, Nokta, XP, Bounty Hunter, Tesoro, Whites, Quest, Rutus).

It’s possible this is:

• A very old / discontinued model (1970s–90s)
• A generic rebrand (common on Amazon/eBay/Alibaba)
• A local market name (India, Middle East, Africa, South America)
• A typo (maybe “Orbitor Prospector 100” vs “Orbitor Pro 100” or “Prospector 100”)

7. Understanding the Audio Feedback System

The Prospector 100 does not have a digital screen for VDI numbers. Instead, it uses a three-tone audio system.

• Low Tone (Growl): Iron, steel bottle caps (usually indicates junk). Dig only if relic hunting.
• Mid Tone (Buzzing): Nickel, pull tabs, gold jewelry (size dependent), shotgun shells.
• High Tone (Clean Bell): Copper pennies, dimes, silver quarters, brass. Always dig.

Broken Signal: A crackling sound that cuts in and out usually indicates a rusted nail or a can near the surface. The manual advises: "If it doesn't sound pretty, it's probably trash." A very old / discontinued model (1970s–90s) A

The Discrimination Dial

Discrimination is a filter. It tells the machine to ignore certain metals.

• Position 0 (All Metal): You hear every piece of iron, nail, and bottle cap. Good for relic hunting.
• Position 3-4 (Iron Accept): Silences most iron nails. Pull tabs still sound off.
• Position 6-7 (Foil Reject): Silences aluminum foil and most gold chains (unfortunately, you will also lose small gold rings).
• Position 9-10 (Pull Tab Reject): Silences modern pull tabs. Use this for coin shooting. You will lose some mid-sized gold rings.

Warning from the manual: “Do not set Discrimination above 8 unless you are specifically hunting for large silver. You will miss all nickel and gold targets.”

The Sensitivity Dial

Higher sensitivity = deeper detection, but more "noise."

• Low (1-3): Super trashy parks with lots of interference.
• Medium (4-6): General hunting, wet beach sand (dry sand).
• High (7-9): Open fields, rural farms. If the detector beeps when you lift the coil, turn Sensitivity down.

Noise Cancellation Trick: If you hear a rapid chirping (electrical interference from power lines), reduce Sensitivity until the chirping stops.
