Connect your detector to GeoDetectit

1. Works with many brands

GeoDetectit is not locked to one detector brand. The app can work with different machines as long as there is an audio signal to read.

• Use a ready-made model profile if your detector already exists in Configure.
• If your model is missing, you can still use the app by calibrating your own profile.
• Signal levels and tone patterns can vary between different detectors.
• The app may therefore need adjustment depending on the model, audio source and connection path.

2. Common ways to connect

• 3.5 mm TRS – most common on modern detectors.
• 6.3 mm TRS – larger jack on some models, used with a small 6.3 → 3.5 mm adapter.
• USB-C audio adapter – for example a BY-K2 type adapter, important that it supports external mic or line-in.
• Y-splitter – optional but useful if you want to hear the detector in headphones while the phone logs the audio.
• Bluetooth receiver – can be used when you get a stable audio signal into the phone.
• Mic mode – also works when the app listens through the phone microphone.

3. If your detector already exists

The quickest path is to choose an existing profile.

• Open Configure in the app.
• Select the correct detector model.
• Choose Input source: Mic, Cable or Bluetooth.
• Test over a clear target.
• Verify that Sound Tuner or signal logging reacts in a stable way.

4. If your model does not exist yet

Then use Sound Tuner to create your own compatible profile.

• Start microphone or cable input in Sound Tuner.
• Sweep over clear targets and watch which frequency areas react.
• Create slots or bands for different signal types.
• Save the profile with a clear name.
• Use that profile in the app as your own model configuration.

Phone mount

A weather-resistant mount on the shaft keeps the map visible and reduces cable strain while walking.

BY-K2 or similar

A simple TRS-to-USB-C adapter is often the easiest way to feed detector audio into the phone.

Short cable = fewer problems

Shorter cable runs and one loop of tape around the shaft reduce the chance of disconnects in the field.

6. Typical cable setup steps

• Connect the detector audio cable into the Y-splitter or directly into the USB adapter.
• Connect the adapter to the phone.
• Connect headphones to the second branch if you use a splitter.
• Open Configure and select Input source: Cable.
• Sweep over a clear target and verify that Sound Tuner reacts.

7. When you need more calibration

• If signals are too weak or too strong.
• If different targets end up in the wrong band.
• If your detector uses a tone profile that differs from the built-in defaults.
• If you switch between mic, cable and Bluetooth and get different levels.
