Use the same connection, firmware and profile when repeating a check. These measurements describe browser input and do not assign a hardware health score.

Trigger Travel · Last 6 Seconds
Slowly squeeze and release each trigger. A digital or instant-trigger mode can jump directly between endpoints.
— Left trigger– – Right trigger
Observed Press / Release Counts
↓ Presses · ↑ Releases. Counts start at observed state transitions; a control already held when sampling begins has no recorded press. Brief events between browser samples can be missed.
How to read these measurements
The guided sweep records the greatest radius in each of 32 direction sectors. A direction counts as covered at radius 0.75. Outline deviation is the mean absolute difference from radius 1, shown only after all directions are covered. An intended square response can have higher deviation.
Centring records four releases per stick: left, right, up and down. After input returns below radius 0.5, it settles for 0.4 seconds and averages the following 0.4 seconds, with at least five samples. Position spread is the greatest distance from the average of those four positions. Filtering can affect all results. This is not a latency or hardware polling-rate test.

Resting-Stick Measurement
This describes the input exposed by your browser. Firmware and remapping software can already apply deadzones. These readings do not certify hardware condition.

Connect Your Turtle Beach Controller
Recon is a wired Xbox/Windows controller. Stealth Ultra is a different family with its own connection and configuration options; use the correct manual for Ultra or Ultra II.
Start with a supported USB or receiver connection and record your profile. Audio controls and built-in controller display functions are separate from the browser’s gamepad input stream.
Confirm the controller’s platform mode and supported connection. Use a USB data cable or the receiver specified for that exact model.
Focus this page, press a face button and choose the responding device from the connected-controller menu.
Press and release each control. Check raw indices if the device has no standard mapping.
Record your connection, software profile and trigger-stop setting before saving a snapshot.

Before You Test
Use wired USB for Xbox/Windows. Audio controls are outside the browser gamepad test.
Start with the normal manufacturer-supported PC connection. Record firmware, connection and profile before saving a snapshot.
What To Check Here
Press each face button and direction once. Use the raw input list if the browser has no standard mapping.
Move the sticks around their range, release them and run the resting-stick test. Save the active profile alongside the results.
Squeeze and release both triggers. A short-travel or digital mode can change the values you observe.
Rear buttons can repeat existing inputs. Browser rumble does not test motion sensors, audio or adaptive-trigger resistance.

Stealth Ultra II includes configurable stick response and gate-shape options. A circular or more square trace can reflect that configuration. The tester’s geometric range display does not award a universal accuracy score.
Rear assignments may duplicate existing controls. Test a direct input and its assigned rear control separately; a matching button index can be expected.
Headset sound, microphone monitoring and controller audio features are not measured here. Use the manufacturer’s audio troubleshooting instructions for an audio-only symptom even if all gamepad inputs work.
Turn A Reading Into A Useful Comparison
Check one variable at a time. For unwanted stick movement, release the sticks onto a stable surface and run the ten-second resting test. For a missing action, compare a direct button press with its rear-button assignment. Save a note identifying the active profile so a later result can be reproduced.
The browser-reported device name can describe a virtual gamepad. The optional model reference is your selection, not automatic hardware identification. Brand listing does not guarantee vibration, independent paddles or vendor-specific controls in your browser.
No. The browser test covers exposed gamepad buttons and axes. Audio, microphone monitoring and display functions need their own manufacturer checks.
Why is my Stealth Ultra II stick outline square?
Gate-shape and response settings can affect the trace. Record those settings, sweep each direction slowly and compare against the same configuration. A round outline is not a universal quality target.
