By purchasing this product you will earn SIGAL Extreme elastic
Elastic with high contraction speed that allows to obtain the maximum performance in the first meters of shooting. The high energy return and the reduced internal hole make it possible to obtain the best performance with less exaggerated stretches than usual.
Elastico Extreme is characterized by a production process in which the pure latex compound is loaded (added) with a small percentage of PAHs (polycyclic aromatic hydrocarbons), to give greater resistance to fatigue and wear, without compromising the natural elastic return, rather enhancing it.
This result is obtained with a particular vulcanizing agent and an extrusion technique different from the usual, which allows to obtain an increase in the cohesion of the molecular structure of the elastomer in the innermost part. In fact, as is known, it is the innermost part, less stressed than the external one, more exposed to stress and atmospheric agents, which supports the latter in resuming its original shape more quickly.
The result is an elastic, with a pasty elongation, an excellent load value and a contraction speed at the highest levels, with a characteristic purplish colour, extremely mimetic.
Available in diameters 13 – 14.5 – 16 – 17.5 – 19 mm.
– DIRECTIONS for making a circular elastic band:
Take the measure L on your speargun.
L = from the notch or from the pin on which the wishbone is to be placed to the seat of the elastic in the muzzle.
14mm elastic bands: (L cm x 2 ) / 3.4
16mm elastic bands: (L cm x 2 ) / 3.2/3.3
ger the cm necessary for the ligatures.
Example: suppose L is 80cm and you need to prepare a 16mm elastic :
80cm x2 = 160cm
160 : 3.3 = 48.48cm
48.48 + 3 cm ( cm for standard bindings) = 51.48 cm
– DIRECTIONS for making a single elastic:
Take the measure L on your speargun.
L = from the notch or from the pin on which the wishbone is to be placed to the seat of the elastic in the muzzle.
14mm elastic: L cm / 3.4
16mm elastic: L cm / 3.2/3.3
add the cm needed for the bindings.
Example: suppose L is 80cm and you need to prepare a 16mm elastic :
80cm : 3.3 = 24.24cm
24.24 + 3 cm (cm for standard bindings) = 27.24 cm
I will then need to cut a 16mm elastic 27.24cm long.
