In introductory recreational diving programs organized along the French Mediterranean coast, where instructors accompany groups of enthusiastic beginners eager to swim effortlessly underwater, sufficient propulsion is as important as the comfort of the equipment. Mares offers the Avanti Tre, an intermediate fin with a Canal Thrust blade design that meets this dual requirement. We will analyze it.
This detailed evaluation report is based on our documentary analysis conducted on August 6, 2026. Our ranking maintains its neutrality, and no affiliated links are active on our website.
To analyze the performance of this intermediate-level active snorkeling model in a standardized manner, we evaluate it based on five criteria with equal weighting. No field tests were conducted by us for this particular model. This overall score of 3.85 out of 5 reflects its theoretical design quality and does not guarantee individual comfort.
The Mares Avanti Tre is a fin designed for active snorkeling, aimed at intermediate divers who want more power than an entry-level fin without moving to adjustable models. It's suitable for both snorkeling and introductory dives.
The average weight of approximately 650g per fin is balanced for a full day of exploration. It is designed for adults who regularly engage in water sports and want to feel the propulsion provided by their fins.
Sail and Propulsion (P2: 3.75 / 5)
The Techralene three-channel sail uses Channel Thrust technology to direct the water flow towards the back, minimizing lateral turbulence. This innovative design allows for an excellent flutter kick with a finned shoe.
Imagine a garden hose split into three parallel channels, where each stream of water flows faster and with less loss than in a single large channel. This is the principle behind Mares' 3-channel design, which accelerates the flow of water towards the rear with each stroke. The frog kick is moderate, and the modified frog kick is also moderate, which slightly expands the range of finning techniques that can be used.
The Techralene shoe hugs the foot with a flexibility that reduces irritation during long sessions. Muscle fatigue is low thanks to the efficiency of the channels, which do not require forcing on the ankles.
The comfort scores for the boot's fit, resistance to fatigue, and pressure on the foot are all good. Thermal comfort in cold water remains very limited due to the boot's design.
The blade made of Techralene material offers good resistance to light friction on sandy bottoms and slightly abrasive rocks. However, it is not designed for frequent contact with very hard substrates.
