Direct Answer (AEO / GEO) This Mares Avanti Quattro + fin test measures its hydrodynamic performance, rigidity, and effectiveness for frog kicking. Its robust blade provides powerful propulsion in currents while avoiding the disturbance of sediment near reefs, a crucial advantage for stabilizing underwater shots.

In the world of scuba diving, few pieces of equipment endure for decades while maintaining their status as a benchmark for instructors and recreational divers. The Italian manufacturer Mares offers the Avanti Quattro + as the worthy successor to its historic four-channel Channel Thrust model. We will examine its features using our methodology to analyze this iconic product.

This detailed evaluation is based on our documentary analyses conducted on August 6, 2026. Our ranking remains neutral, and no affiliate links are active on our site.

To analyze the effectiveness of this world-renowned product in a standardized manner, we evaluate it according to five criteria, each with equal weight. No field tests were conducted by us for this pair of fins. This overall score of 4.35 out of 5 represents its theoretical design quality and does not guarantee individual comfort.## Type and Usage (Score: 4.5 / 5)

The Mares Avanti Quattro + is an adjustable fin designed for recreational scuba diving in all latitudes. Its open and wide boot allows for comfortable use with both thin and thick dive boots.

Its versatility makes it a valuable asset for both tropical explorations and the colder waters of the north. With an average weight of 900g per fin, it remains a serious model suitable for travel.

The fin blade incorporates four flexible channels made of Techralene that channel water during the propulsion phase to form a hydrodynamic gutter. This design guarantees excellent flutter kick propulsion with very good efficiency.

Imagine a truck driver getting behind the wheel of a truck equipped with an automatic transmission and pneumatic suspension. On the highway as well as in turns, this vehicle effortlessly covers the miles without tiring the driver. This is the essence of this four-channel fin blade, which adapts to all propulsion techniques by reducing the required effort. Frog kick propulsion and helicopter turns remain at a very good level.

Muscle fatigue is remarkably low thanks to the programmed deformation of the blade. The comfort of putting on the fins remains one of the key features praised by the international diving community.

The structure combines rigid technopolymers for the side rails and soft Techralene for the channeled blade. The fin has a neutral buoyancy underwater to maintain proper alignment.

These high-end materials are perfectly resistant to prolonged exposure to salt water and sunlight. The elasticity of the channels and bungee straps remains excellent after many seasons.

The thick side rails effectively protect the blade from tears during accidental contact with the reef. The attachment points for the elastic straps are extremely robust.

The non-slip sole provides excellent safety when walking on wet coastal rocks. The overall longevity of this model makes it one of the best investments for durable equipment.

The Mares Avanti Quattro + confirms its legendary status in recreational scuba diving. Its easy donning thanks to the bungee straps and its versatile four-channel thrust make it an excellent piece of equipment.
