FIFISH V-EVO Support

Use the FIFISH APP listed on this support page for your device and region. Download options may include iOS, Google Play, or APK where available.

Power on the device and follow the connection steps shown in the user manual and app interface. If pairing fails, check your app version, device permissions, connection status, and the troubleshooting section.

Before first use, fully charge the battery, review the quick-start or user manual, confirm your app version, check storage availability, and make sure all external parts and connections are properly secured.

Ensure both the V-EVO and the remote controller are fully charged before use.

Step 1 — Hardware Connection:
- Plug the tether (3.5 mm plug) into the remote controller.
- Connect the tether cable to the FIFISH V-EVO's communication port (Ensure the safety loop is secured to the tail wing).
- Power on the remote controller. The ROV will power up automatically once connected to the active controller.

Step 2 — Software Connection:
- Open the FIFISH App on your smartphone or tablet.
- Connect your device to the remote controller's Wi-Fi network (Name starts with “FIFISHRC_”; Wi-Fi Password: 1234567890).
- Return to the APP and connect to the ROV.

Step 3 — Pre-Dive Calibration:
- Perform sensor calibration as prompted by the App and verify that the live video feed is working.
- Gently lower the FIFISH V-EVO into the water (DO NOT throw it).

For detailed operation guides, please refer to the user manual and the tutorial videos.

The robotic arm (available as an optional accessory or within the V-EVO Arm Pack) is operated directly via the remote controller.

Installation (Ensure ROV is Powered Off):
- Attach the robotic arm bracket to the designated mounting hole on the underside of the V-EVO body.
- Secure the arm’s connector cable to the Q-Interface port.
* Note: For detailed visual guidance, please refer to the User Manual or the official tutorial video.

Operation (Ensure ROV & Remote are Powered On):
- Switch the control gear to A-Mode (located on the top-left corner of the remote controller).
- Rotate the right dial (located on the top-right corner of the remote controller) right to open the claw and left to close it.

You can access the latest manual, video tutorials, and other support resources directly on this page under the relevant sections.

APK download is available where listed on this support page. Please use the version provided for your product and follow the installation guidance shown on the download page.

Yes. FIFISH V-EVO supports both photo capture and video recording. Use the camera controls in the FIFISH app or controller interface to switch modes and capture content. Available settings may vary by app version and system configuration.

With settings in the FIFISH APP, images and videos can be transferred in two ways:

1. From the FIFISH ROV to the MicroSD card inserted in the controller
2. From the FIFISH ROV to your personal smart device

You can broadcast live video directly to YouTube, Facebook, or other platforms using the FIFISH App.

Step-by-step Guide:
- Obtain a Stream URL and Stream Key from your YouTube or Facebook account.
- In the FIFISH App interface, tap the "LIVE" icon.
- Paste the Stream URL and Stream Key into the designated fields.
- Select your preferred Live Stream Quality (High, Medium, or Low).
- Tap “Start Live Streaming” to begin.

Notes:
1. This feature requires an iOS device (e.g., iPhone or iPad with cellular capability).
2. Live streaming consumes significant cellular data. Please ensure your data plan has sufficient allowance.
3. Stream quality and stability are highly dependent on your local 4G or 5G network speed.

Under ideal conditions, FIFISH V-EVO can operate for up to 3 hours in hover conditions. Actual runtime will vary depending on maneuvering intensity, lighting use, water conditions, and other operating factors.

Proper post-dive care extends the life of your V-EVO. After Every Dive:
- Connect the V-EVO with remote controlller.
- Submerge FIFISH V-EVO in clean freshwater (especially after saltwater use).
- Connect the remote controller, open the FIFISH APP and go to "Help" > "Maintenance/Thrusters", and press "Start".
- Motors will run slowly for approximately 10 minutes to flush out salt and chlorine.
- Dry in a shaded, ventilated area. Avoid direct sunlight.

For long-term storage of FIFISH V-EVO:
- Battery Level: Maintain battery charge at 50%–60%.
- Recharge Cycle: Charge the battery every 90 days to prevent deep-discharge degradation.
- Storage Environment: Keep in a cool, dry place away from direct sunlight.
- Pre-Usage: Before your next dive, fully charge FIFISH V-EVO and perform a sensor calibration via the FIFISH APP.

When connecting a new device for the first time, the FIFISH APP requires specific system permissions to communicate with the ROV. Please ensure the following:

Grant Permissions: During the initial launch on your new device, you must select "Allow" or "Enable" for all permission prompts, including Local Network (for communication), Photos/Media (for storage), Location (for calibration/mapping), and Notifications.

If you previously denied these, go to your device's Settings > Apps > FIFISH and manually enable them.

A is Attitude mode, S is Sport mode, and C is the Combination mode.

A Mode / Attitude Mode
A Mode is designed for beginners. The ROV will not roll in A Mode. The ROV will stay in same depth moving when depth holding is ON. Even with pitch angle, the depth will be the same.

S Mode / Sport Mode
S Mode is designed for skillful pilots. S Mode will enable the rolling freedom, so you will access all 6 degree of freedom of V6 Expert. Controlling and moving based on the FPV (Frist Person View), do not operate in third person view. The ROV will only stay in the same depth with no command input, when depth holding ON.

C Mode / Combination Mode
C Mode activates the head tracking controlling via the VR Goggle, which allow pilot to use the VR Goggle to pitch, roll and yaw. C Mode delivers the intuitive control and immersive experiences. C Mode supports head tracking and remote controller working together.

Accessories Attached
The right wheel will ONLY be working in A Mode or C Mode for motor driven accessories. For example, robotic arm, water sampler, robotic fish clamp, and compass ruler, and sludge sampler etc.
