<p>Trail Sense is a tool, and just like any other tool that you bring into the wilderness,
it's essential to have backup equipment and skills.
This app is intended for information purposes only and the accuracy of the predictions and sensors are determined by a number of factors, including calibration, sensor quality, external sources, etc.
Use at your own risk, always have backup tools (ex. compass), and stay safe.</p>

<p>This app also does not, and will never, use the Internet - all information in Trail Sense comes directly from your phone's sensors, and no data will leave Trail Sense.</p>

<h3>COMMON ISSUES</h3>
<ul>
<li>No compass: If your phone does not have a compass sensor, there is nothing I can do to make it work because that is hardware.
You will still be able to use other features of Trail Sense.</li>
<li>No weather: The Weather tool is only available if your phone has a barometer sensor.</li>
</ul>

The Sensors tool can be used to test the sensors on your device.

## Sensor List
The sensor list shows all the sensors available on your device that Trail Sense uses. If the accuracy of the sensor is available, it will be shown on the left, and the sensor's value will appear to the right of that.

## All Sensors
To see all available sensors on your device, click the button in the top-right corner of the screen. This will show a list of all sensors available on your device, including those that Trail Sense does not use.

The Metal Detector tool allows you to detect magnetic metals like iron. It's useful for finding dropped keys or knives. It cannot detect coins or jewelry.

## Calibration
Calibrating the metal detector improves the accuracy of readings. To calibrate:

1. Hold your phone 2-3 inches (5-8 cm) above the ground with the screen facing up.
2. Press 'Calibrate'.
3. Recalibrate occasionally for accuracy.

The detector automatically calibrates when started.

## Detecting Metal
The detector only finds magnetic metals like iron. To detect metal:

1. After calibrating, hold your phone 2-3 inches (5-8 cm) above the area to scan with the screen facing up.
2. Slowly move your phone, keeping the distance and orientation consistent.
3. When metal is detected, the phone will vibrate and indicate detection.

## Understanding Readings
The graph shows magnetic field strength over time. Metal causes spikes up or down. If spikes occur that don't trigger the metal detector, lower the threshold to increase sensitivity.

Readings at the top of the screen show field strength in microteslas (uT).

## Threshold
Lower threshold values increase sensitivity. Higher values decrease it. Adjust with the on-screen slider.

## High Sensitivity Mode
This removes noise filtering for maximum sensitivity. The graph becomes noisier and false positives occur more frequently. Enable with the 'High sensitivity' switch.

## Audio Feedback
Tapping the speaker icon in the top-right corner enables audio feedback. A tone will play when metal is detected, and the volume increases with field strength.

## Metal Direction (Experimental)
This experimental feature attempts to indicate metal direction with two on-screen dots. One points towards the metal and the other away from it. Unfortunately, it's uncertain which is which. Move your phone towards one dot; if the number in the center increases, you are getting closer. If the dots swap, it likely means you just passed over the metal. This requires a gyroscope sensor.

Enable it on Settings > Experimental > Show metal direction.

## Beacons
Nearby beacons are displayed as markers on the screen. You can tap on a beacon to start navigation (See the Navigation section below). The view distance can be adjusted in Settings > Augmented Reality > Beacons > "View distance".

## Paths
Nearby paths are displayed below your feet. Due to GPS inaccuracy, the paths may not be perfectly aligned with the real world. The view distance can be adjusted in Settings > Augmented Reality > Paths > "View distance"

You can choose to adjust paths using their recorded elevation by enabling Settings > Augmented Reality > "Use path elevation". This should make the paths line up better with hills and valleys, but is dependent on the accuracy of the elevation data.

## Sun / Moon
The paths that the sun and moon will take today are displayed as markers on the screen. The sun's path is displayed in yellow and the moon's path is displayed in white. A larger marker is displayed at the current time, and will also show the moon phase. Times in the past are lighter.

If you bring the sun or moon into the reticle, you will see more details about the marker such as the time.

If you tapped the "View in 3D" button on the Astronomy tool, you can use the guide to see where the sun or moon currently is and change the previewed date in the bottom panel.

## Grid / Compass
A grid is displayed on the screen to help orient you. The grid is aligned with the cardinal directions and is spaced at 30 degrees. The grid line for North is highlighted in orange. The cardinal directions are displayed over the grid.

## Orientation
The orientation of your device is displayed at the top of the screen. This includes the compass bearing and the tilt angle. The Augmented Reality tool respects the True North setting found on Settings > Sensors > Compass > True North.

## Navigation
Tap on a beacon to navigate to it.

While navigating, you will see an arrow around the reticle pointing in the direction of the beacon. Move your phone toward the arrow to bring the beacon into view. When the beacon is in the reticle, the arrow will disappear.

## Calibration
If the Augmented Reality tool is not aligned with the real world, you can calibrate it by tapping the compass icon in the top-left corner of the screen. This will prompt you to center either the sun or moon in the reticle and click "Calibrate".

Always check the accuracy against the sun, moon, or known landmarks before using this tool. Depending on the quality of your phone's sensors, you may need to repeat calibration frequently.

You will not be able to calibration on a moonless night.

If your device has a gyroscope, calibrating will switch the tool to use the gyroscope for orientation. You can disable this in Settings > Augmented Reality > "Use gyroscope after calibration".

To reset the calibration, long press the compass icon or close and reopen the tool.

### Accuracy
The accuracy of the compass and GPS are shown in the bottom-left of the screen. You can tap the status icons to see more details about the accuracy and for further instructions on calibrating your compass.
