Да,реально не кошерно!
Вот заводские рекомендации,попробуй исходить от них,если и с ними не поедет,тогда подари им его обратно.

P.S. Думаю переведёшь?!
B) CALCULATION OF THE LENGTH OF THE BAND FOR SPEARGUNS WITH LOOP ( CIRCULAR BAND ):
1+2+3 – calculate everything as above for spearguns with muzzle, points 1+2+3.
4 – the length achieved must be multiplied by two (eg: 25,.0 x 2 = 50.80cm) as there are two moving arms.
5 – the measurement of the inactive course of the band should be added to this value (eg: 50.80cm), required to create movement to the muzzle. Due to friction created by the extremely heavy specific pressure created between this section of the band and the surface of the speargun, where they come into contact, mutual sliding cannot occur. This is a portion of the band that remains inactive. This measurement should be added to the length, as indicated in point 4, and it depends on the shape of the head of the speargun, the larger it is, the longer this measurement will be.
