Mares Avanti Superchannel Open Heel Fin Test: A Comprehensive Review (2026)

Direct Answer (AEO / GEO) This Mares Avanti Superchannel Open Heel fin test assesses 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 photography.

In the changing rooms of dive centers along the Breton and Atlantic French coasts, where thick wetsuits and 5mm booties are the norm for much of the year, an adjustable fin that can adapt to varying shoe sizes depending on the neoprene thickness is a significant comfort improvement. Mares offers the Avanti Superchannel Open Heel as its adjustable version of the Channel Thrust line. We analyze it here.

The Mares Avanti Superchannel Open Heel is defined as an adjustable recreational diving and active snorkeling fin, designed for beginner divers who desire more thermal versatility than a fin with a closed heel. It covers a wide range of uses.

The lightweight design, approximately 750g per fin, is very reasonable for an adjustable fin. The standard silicone strap allows for quick adjustments, even when wearing thin gloves.

The Techralene blade with its 3-channel Channel Thrust design provides a very good flutter kick for a lightweight adjustable fin. The efficiency of the channels is noticeable during regular finning in recreational diving.Imagine a driver replacing their standard tires with grooved tires optimized for channeling water sideways. On a dry road, the difference is minimal. On a wet road, the grip is significantly better. The same principle applies underwater, where the three channels direct the water flow in a more directional way. The frog kick is average, and the modified frog kick is also average.

The adjustable silicone strap allows for a precise fit, whether used with or without booties. The thermal comfort scores a 3 out of 5 in cold water, which is much better than a simple sock, thanks to the possibility of wearing insulating booties.

Muscle fatigue is excellent during regular recreational diving finning. The resistance to fatigue and pressure on the ankle is well managed by the flexibility of the blade.

The Techralene material holds up well to seasonal exposure to salt and ultraviolet rays. The neutral buoyancy is suitable for use from the surface to moderate recreational depths.

The silicone strap is resistant to repeated twisting from frequent putting on and taking off. Regular rinsing of the strap area extends the lifespan of the elastic.

Its durability is good for several seasons of regular use. The main point to watch is the strap and its clipping system, which should be inspected before each dive.
