Dyno Segment is an additional 1kg weight for the Dyno freediving collar.

Being able to increase the weight of the collar by 1kg using just 1 additional piece makes the collar more stable during use, especially when turning at the end of the pool. This is the  time when a long tail of weights could move, creating discomfort and unbalancing the freediver.

Another advantage that should not be underestimated is that, by adding this single weight, a good distribution of weight is maintained on the freediver’s back, without placing a greater burden on the area around the neck.

Assembly is recommended only and exclusively starting from the second vertebra of the Dyno collar.
