The Dyno Collar from 4.0 kg is the newest modular weight system made by the C4 brand. This freediving neck weight has a highly hydrodynamic shape, designed at length not to overload the swimmer's neck and to make freediving much more effective. The weight goes to work much closer to the point where the buoyancy forces balance, and because of the semi-mobile segments that follow the movement of the dorsal vertebrae, the swimmer is not restricted in any way in his or her movements. The segments are modular and variable in weight, attached by axles with screws, easy and convenient to assemble and disassemble so as to adapt the weight of the collar to any need. You can add additional Dyno segments weighing 280 grams, sold separately. Color: Black. Read more
