The First Scuba Gear to Buy (And What to Rent)
The Golden Rule: Don’t Buy Everything on Day One
One of the easiest ways to waste £1,500 is walking into a dive shop before your first Open Water course and buying a complete kit.
Until you have completed 15 to 25 dives in real ocean conditions, you do not know:
- Whether you prefer back-inflate or jacket-style BCDs.
- How fast you consume air and whether you need lightweight travel regulators.
- How cold-tolerant you are and whether a 5mm, 7mm, or drysuit suits your long-term diving plans.
Here is the smart, tiered purchasing strategy recommended by experienced instructors.
Tier 1: Buy Before or Immediately After Your Course
These items directly touch your face and body. Comfort and fit make or break your diving experience.
Cressi Big Eyes Evolution Mask
£45 – £65The Verdict: The single best personal upgrade a new diver can make. Eliminates rental mask leakage and provides expansive downward peripheral vision.
- Hypoallergenic liquid silicone seal stops persistent bridge-of-nose leaks
- Raked tempered glass lenses allow quick glance down at SPG and compass
- Compact travel case protects silicone skirt during transit
- Requires proper pre-dive defog treatment
- Must be fitted against your own face geometry to ensure complete vacuum seal
Mares Avanti Quattro+ Fins & 5mm Boots
£120 – £160 (Fins + Boots)The Verdict: Open-heel fins with bungee straps paired with 5mm neoprene zipped boots protect your feet during rocky shore entries and deliver maximum thrust in current.
- Heavy-duty bungee heel straps can be donned or removed in 2 seconds
- Neoprene boots provide thermal insulation and grip on slippery boat ladders and rocks
- Four-channel blade delivers power for both flutter and frog kicks
- Boots and open-heel fins take up more luggage space than barefoot full-foot fins
3. Surface Marker Buoy (SMB) & Finger Spool (£25–£45)
- Why you need it: If you surface away from the boat or drift in a current, deploying an SMB makes you visible to skippers. Many marine reserves legally require every diver to carry an SMB.
Tier 2: Buy Once You Know You Love the Sport
Mares Puck 4 / Suunto Zoop Novo
£160 – £220The Verdict: Owning your own computer eliminates the stress of deciphering unfamiliar rental interfaces. Clear depth, NDL, and 3-minute safety stop countdowns.
- Consistent, familiar alarm tones and ascent rate visual warnings
- Supports Nitrox mixes from 21% to 50% or 99%
- Built-in logbook keeps an accurate record of maximum depth and bottom time
- Monochrome display (full-colour screens like Shearwater start at £420)
Tier 3: Rent Until You Reach 30+ Dives
Leave these in the rental room for your first few holidays:
- BCD (Buoyancy Control Device): Rental jackets work perfectly while you learn your baseline weighting.
- Regulators: Good regulators cost £400–£800 and require annual servicing (£100+). Rent until you dive frequently enough to justify maintenance costs.
- Wetsuits: Different destinations require radically different thicknesses (3mm shorty in Thailand, 5mm–7mm in Lanzarote, drysuit in the UK). Renting allows you to adapt to the local water temperature without overpaying for excess baggage.
