FIFISH QYSEA V6 Expert M100A Underwater Drone with Robotic Arm

Quick take

The FIFISH QYSEA V6 Expert M100A is a tethered underwater ROV that combines 4K UHD imaging, AI vision lock, and a robotic arm for inspection, sampling, and grapple-style tasks. It targets buyers who want longer powered dives and quicker media handling, but it is tether-dependent, so your effective working area is limited by the included 330 ft cable.

Pros and cons

Pros

  • Up to 6 hours of working time with a 14,400 mAh battery and fast charging (listed to reach 90% in 1 hour).
  • 4K UHD camera with a wide 166° field of view and built-in LED lighting rated up to 6000 lumens.
  • AI vision lock is designed to help maintain visual targeting in challenging underwater conditions.
  • Removable micro SD workflow (includes a 128GB card) for easier transfers.
  • Robotic arm included in the M100A package for added task capability.

Cons

  • Tethered operation limits range, and this M100A package uses a 330 ft tether.
  • AR headset support is mentioned as needing an additional purchase, so you may need extra accessories for certain setups.
  • Review evidence is limited, so buyer patterns are based on a small amount of feedback.

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence is limited (only a small number of ratings and comments). The feedback that is available highlights one practical advantage: having a removable SD card to swap storage media without waiting to download. Beyond that, there is not enough review depth to reliably identify consistent patterns around image quality, build durability, connectivity reliability, or day-to-day control behavior.

Who this underwater drone is for

This is the kind of underwater drone you consider when you want more than basic video capture. The FIFISH QYSEA V6 Expert M100A is positioned for buyers who need:

  • Higher-detail underwater video and stills, thanks to a 4K UHD camera and wide-angle lens.
  • Lighting for visibility in darker environments, with LED output up to 6000 lumens (two lights).
  • Extra capability beyond “just filming”, because the M100A package includes a robotic arm.
  • A practical media workflow, since the system supports removable micro SD storage and includes a 128GB card.

Key features that matter in real use

Imaging: 4K video, wide field of view, and onboard lights

The system is designed around a 4K UHD camera and a 166° field of view to capture more of the scene in a single shot. It also includes LED lighting rated up to 6000 lumens, which is especially relevant for underwater work where ambient light drops quickly.

AI vision lock for targeting

AI vision lock is built in to help the drone maintain visual targeting. This can be useful when you are trying to hold the camera on a feature, inspect an object, or keep framing consistent while maneuvering.

Battery life and charging

The M100A configuration is listed with a 14,400 mAh battery and up to 6 hours of working time. Fast charging is also a stated highlight, with the ability to reach 90% charge in about 1 hour (charging behavior can still vary with charger and conditions).

Range and tether behavior

Maximum dive range is listed at 330 ft for this M100A package. Because it is a tethered ROV, your movement and operational reach are inherently tied to where you place the surface station and how much tether you deploy.

Media handling with removable micro SD

The drone includes removable micro SD storage, and it comes packaged with a 128GB card for storing MP4 video and supported image formats (DNG, JPEG). This matters if you prefer to pull the card and transfer files directly rather than relying on a more time-consuming download process.

Package differences and what makes the M100A distinct

Reviewed productBuy on Amazon

The M100A package is built around industrial case storage and includes the robotic arm, paired with a 330 ft tether reel. If you are choosing between packages in this product family, the practical differences are:

  • M100 vs M200: tether length, 330 ft vs 660 ft.
  • With vs without robotic arm: the M100A/M200A bundles add the arm for additional manipulation tasks.
  • Packaging: the M100A is paired with an industrial case setup.

Pros and cons recap (is it a fit?)

  • Best for: buyers who want a tethered underwater ROV that can do both capture (4K) and task-focused work (robotic arm), especially when longer runtime matters.
  • Consider if you: frequently deal with low-visibility water where strong LEDs and a wide-angle camera help.
  • You may want to look elsewhere if: you need maximum untethered freedom, you require a setup that works entirely out-of-the-box with advanced headsets, or you are budget-sensitive to the cost of a higher-end ROV system.

Alternatives to consider

If you are comparing options, use these decision criteria rather than just spec sheets:

  • Need a robotic arm? If you only want underwater footage, you may be better served by a simpler camera-first ROV without manipulation hardware (often simpler to set up and operate).
  • How far will you operate? For larger areas, a longer tether configuration can reduce repositioning needs.
  • How important is removable media? If quick file handling is a priority, prioritize systems that support removable storage and make transfer straightforward.
  • Lighting requirements: For darker water, prioritize LED output and beam usability over raw camera resolution alone.
