About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

CRESSI
F-DUAL Premium Snorkel Set

Product description of the manufacturer

The CRESSI F-DUAL Premium Snorkel Set combines the high-quality F-DUAL diving mask with the advanced Supernova Dry snorkel – a well thought-out solution for anyone who wants to enjoy comfortable and safe snorkelling. The mask with one lens impresses with a particularly wide field of vision, low internal volume and a comfortable fit thanks to adjustable strap buckles. The dry snorkel with float valve effectively prevents the ingress of water – even in the event of waves or brief submersion. In addition to excellent workmanship, the product also offers outstanding wearing comfort. However, better cleaning of the mask in hard-to-reach areas would also be desirable.
During the test, we were particularly impressed by how reliably the snorkel worked and how comfortable the mask was to wear, even during prolonged use. This makes the set ideal for beginners and ambitious snorkellers.

  • Very wide field of vision
  • Dry snorkel with non-return valve
  • Pleasant wearing comfort
  • Secure fit of the mask
  • High-quality workmanship
  • Slight residue after cleaning

Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

In the practical test, the CRESSI F-DUAL Premium Snorkel Set was convincing almost across the board. The snorkel offers a very good fit, with only minimal adjustment required for optimum comfort. The breathing flow was particularly positive – even when breathing intensively, the resistance remained low and did not disturb the user.
The mask impressed with its wide, undistorted field of vision, which makes the underwater experience much more pleasant. Cleaning the mask was also largely problem-free; only in hard-to-reach corners could a small amount of residue remain.
When it came to transport and storage, the set was compact and uncomplicated. Only minimal adjustments are necessary in the household to store the product safely.
To summarise: the manufacturer keeps its promises, especially in terms of comfort, quality and functionality.
