The Quest Scuba Tector Pros modular design makes switching to the STP20 coil surprisingly straightforward. This coil change transforms your pinpointer into a more versatile detecting tool for underwater treasure hunting.
The process involves removing the control pod from your Scuba Tector Pro and transferring it to the STP20 coil assembly. Here's how to do it properly.
Removing the Control Pod from Scuba Tector Pro
Start by preparing your detector for disassembly. Make sure it's powered off and dry before you begin.
- Unscrew the Scuba Tector Pro battery cap completely.
- Locate the small screw securing the detachable control pod.
- Remove this screw carefully - it's small and easy to lose.
- Gently pull the control pod straight out of the handle assembly.
The control pod should slide out smoothly once the securing screw is removed. Don't force it - check that you've completely removed the screw if it feels stuck.
Installing Control Pod into STP20 Coil
The STP20 coil uses the same control pod system, but proper alignment is critical for a secure connection.
- Examine the slide rails on both the control pod and the round STP20 coil handle - they must align perfectly.
- Insert the control pod down into the STP20 handle, following the slide rail guides.
- Push firmly until you hear a distinct click sound - this confirms proper seating.
- Replace and tighten the securing screw snugly, but don't overtighten.
Essential Coil Retune Process
Any time you change coils on a Questmetal detector, you need to retune the system to prevent false signals and optimize performance.
- Position the detector away from all metal objects - at least 3 feet from anything metallic.
- Ensure the angle between handle and coil exceeds 90 degrees, then power on.
- Locate the RESET button inside the body compartment.
- Press and hold the RESET button for approximately 2 seconds.
- Listen for the confirmation sequence: one long beep followed by two short beeps.
This reset calibrates the detector to current ground conditions without changing your saved settings. The detection range must be completely clear of metal during this process.
Final Assembly and Testing
With the control pod properly seated in the STP20 coil and the retune complete, you can reassemble everything.
Replace the battery cap and ensure it's properly sealed - this maintains the waterproof integrity essential for underwater detecting. Before heading out, test the detector on a known target to confirm everything's working correctly.
Always review the complete Scuba Tector Pro operation manual before each detecting session, especially when using different coil configurations.
