Mares Avanti Quattro+ Open Heel Scuba Diving Fin

Mares Avanti Quattro+ Open-Heel Scuba Diving Fin

We call the Avanti Quattro+ the Honda Accord of fins — they don't do anything spectacular, but they don't do anything wrong either. Think of it this way: a dive professional who works in a scuba store has to wear whatever brand their store carries. But independent instructors, divemasters, and underwater photographers — the ones with no brand loyalty required — consistently choose these fins when they can pick anything they want. That's the most honest endorsement in diving.

Channel-Thrust Blade Technology

The Quattro+ uses Mares' signature Channel-Thrust blade, which bends during your kick to form a flexible channel. Instead of pushing water outward like traditional flat fins, it funnels water straight behind you — where propulsion actually matters. The result is less wasted energy and more speed per kick.

Bungee Strap System

The pull-tab heel loop makes donning and doffing fast — no adjusting buckles underwater, and the strap stays flexible even in cold water. Once divers switch to bungee straps they never go back to traditional buckles.

Perfect For

Recreational divers, drift diving, liveaboard diving, underwater photographers, and anyone diving in current — including the Gulf of Mexico, Flower Garden Banks, Cozumel, and Bonaire.
