Review: Mares Avanti Quattro+ Power — The Dive Fin That Refuses to Be Replaced
The Mares Avanti Quattro+ Power has been one of the world's bestselling scuba fins for over a decade. Its combination of efficient blade geometry, Reactive Compound Blades technology, and a spring strap system that makes donning and doffing effortless continues to justify its place in dive bags worldwide.
Some dive gear stays in a manufacturer's lineup because it works. The Mares Avanti Quattro+ Power is the clearest example in the fin category — a design first introduced in the 1990s that has undergone incremental refinement but has never needed fundamental rethinking, because its core engineering is simply very good.
The Avanti Quattro+ Power is an open-heel scuba fin designed for use with boots, available in sizes XS through XXL and a wide range of colour combinations. The blade is constructed using Mares' Reactive Compound Blades (RCB) technology, combining a stiffer midsection with softer outer edges. This creates a fin that provides meaningful propulsion without demanding excessive ankle and calf effort — a balance that makes it sustainable across multi-dive days without the accumulated fatigue that stiffer, higher-output designs can cause.
The spring strap system is the practical standout. Replacing the traditional buckle-and-strap with a loop of stainless-steel spring, it allows divers to don and doff the fins in seconds with one hand — a minor convenience in isolation but a meaningful one across years of diving and dozens of boat entries. Replacement springs are widely available and inexpensive.
Thrust efficiency sits in the mid-performance range. The Quattro+ Power is not a high-output fin suited for strong currents or technical diving, but it delivers comfortable, efficient propulsion for the conditions that occupy the vast majority of recreational dives. Divers transitioning from softer recreational fins will find an improvement in response without the calf burn associated with stiffer alternatives.
Durability is a consistent selling point in long-term user reviews. The thermoplastic rubber blade retains its flexibility and structural integrity well across years of regular use, UV exposure, and saltwater cycling. At its typical retail price of $100–130 USD, the Avanti Quattro+ Power represents long-term value that has kept it in dive bags around the world for a generation.
Available through Mares authorised dealers worldwide in a range of colour options.
