Two brands, two ways of working

Both Qysea and Chasing offer mature and user-friendly systems, but with a different approach. Browse all underwater drones or go directly to Qysea and Chasing.

  • Qysea: more expansion options, stable and designed for longer operations
  • Chasing: more flexible and focused on fast deployment and continuous use

You will especially notice this difference when using the drone multiple times in a single day.

In practice

Qysea: stable and well thought out

Within the Qysea range, each model is clearly positioned:

  • The Qysea V-EVO is popular for private use and lighter applications such as visual inspections. It is accessible and easy to get started with.
  • The Qysea Expert stands out with its fast charging cycle, reaching up to 90% in about an hour, combined with many configuration options. This makes it very practical for more intensive use.
  • The Qysea E-Master and E-GO are focused on professional applications such as inspection, measurement and research. With swappable batteries and expansion options, these are true workhorses.
  • The Qysea W6 is built for heavy-duty industrial applications. With its higher weight and strong performance, it is one of the more powerful systems in this segment.

Chasing: flexible and efficient

Chasing mainly stands out because of its flexibility:

  • The Chasing Mini S is an entry-level model. It is fun for private use but comes with limitations. The drone cannot move sideways and always needs to move forward in a curve.
  • The Chasing M2 S Lite offers a professional entry point and is strong in visual tasks such as inspections. With a 97.68Wh battery, it is also easier to take internationally.
  • The Chasing M2 Pro Max and M2 Pro are the main workhorses in the M2 series. With swappable batteries and the option for shore power, they offer long operating times.
  • The Chasing X is the industrial model within the range. With a speed of 4.5 knots it is the fastest in the lineup, but also one of the heaviest.

When do you choose which brand?

Choose Qysea if you:

  • carry out long inspections
  • need stability and reliability
  • work with sensors or sampling tools
  • require more expansion options

Qysea clearly offers more flexibility in this area, especially in the higher-end segment.

Choose Chasing if you:

  • perform many short or consecutive deployments
  • want to keep working without long charging breaks
  • need flexibility in power options such as batteries or shore power
  • prefer a practical and mobile setup

The combination of swappable batteries and shore power is a key advantage here.

Camera and image quality

Many people focus on the camera, but in practice the difference is smaller than expected. Image quality across the different series and brands is quite comparable. The choice between Qysea and Chasing is therefore not based on the camera, but mainly on:

  • operating time
  • workflow
  • flexibility

Pros and cons at a glance

Qysea

  • very stable and reliable
  • fast charging options such as the Expert
  • many expansion options including sampling
  • less flexible in power usage for models without swappable batteries

Chasing

  • swappable batteries in the M2 series
  • shore power available for extended use
  • flexible and efficient workflow
  • Mini series less suitable for professional use

The choice between Qysea and Chasing is not about better or worse, but about how you plan to use the system.

  • If you work for long periods and need stability and expansion options, Qysea is often the better fit.
  • If your work is mainly visual and involves many consecutive tasks, Chasing may be the more practical choice.
