Mask, Fins & Snorkel: How to Choose Without Wasting Money

By How2Scuba Editorial TeamUpdated: 10/8/2026

The Mask: Fit Trumps Brand Every Time

Your mask is your window to the underwater world. A £120 titanium-framed mask that leaks every 30 seconds is worthless, while a £40 mask that seals perfectly will last you 10 years.

How to Test Mask Fit in a Shop

  1. Place the mask against your face without the strap around your head.
  2. Make sure no hair is caught under the silicone skirt.
  3. Inhale gently through your nose and take your hands away.
  4. Look straight down and turn your head gently. If the mask stays firmly attached by light suction alone, it fits your facial structure.
Scuba & Snorkel MaskBest All-Round Fit

Cressi Big Eyes Evolution

£45 – £65

The Verdict: Inverted teardrop dual lenses provide 30% wider downward field of view, making it easy to check chest gauges and tank valves without nodding your head.

✓ Why it wins
  • High Seal hypoallergenic liquid silicone skirt molds softly to facial contours
  • Raked lenses give exceptional downward visibility for monitoring equipment
  • Micro-metric quick-adjust buckles integrated directly into the frame
  • Available in crystal clear silicone or anti-glare black skirt
✕ The Trade-offs
  • Dual lens format means a bridge sits over the nose (some prefer single frameless glass)
  • Requires thorough initial toothpaste scrub to clear factory release agent

Clear vs Black Silicone Skirts

How to Stop a New Mask From Fogging

All new scuba masks arrive with an invisible layer of silicone mould-release agent on the tempered glass:

  1. The Pre-Treat: Rub standard non-gel white toothpaste vigorously over both sides of the lenses using your fingers, let sit for 10 minutes, and rinse thoroughly. (Do not use whitening or abrasive bead pastes).
  2. Before Every Dive: Apply a drop of commercial defog or diluted baby shampoo to dry lenses, rinse once in sea water, and put the mask on immediately.

Fins: Open-Heel vs Full-Foot

Open-Heel Power FinsIndustry Gold Standard

Mares Avanti Quattro+

£95 – £130

The Verdict: The world's most popular dive fin for four decades. Four-channel blade technology channels water efficiently for frog kicks, flutter kicks, and strong ocean drift.

✓ Why it wins
  • Bungee heel straps fitted as standard for instant one-handed donning and doffing
  • Channel Thrust technology provides immense propulsion in high-current drift dives
  • Virtually indestructible composite construction withstands rocky shore entries
  • Works perfectly with standard 3mm to 6.5mm neoprene dive boots
✕ The Trade-offs
  • Requires open-heel dive boots (adds bulk to lightweight carry-on luggage)
  • Blade length can be stiff for divers with low ankle mobility

Full-Foot Fins

Paddle Fins vs Split Fins


The Snorkel: Keep It Simple

Do not spend £50 on an over-engineered snorkel packed with complex flotation valves and bulky dry-caps.
