Those shown in these two videos are the most common knots used for spearfishing. They represent the basis for handle a speargun. We will show the constrictor knot to secure the eyelets in the bands, the knot to create the eyelets and the slip knot to create the loading handle for the
PICASSO MAGNUM CARBON ROLLER 95 THE TEST AT SEA
I finally managed to bring in the water the new Picasso carbon rollergun I had written a few days ago a presentation about. Given the absolute absence of fishes I could not add any “in action” clip to this article but thanks to the unusual water clarity I succeeded in filming a good target shooting test.
As you can see in the video attached the balance of the gun is perfect and requires no effort at the time of aiming so the wrist remains adequately relaxed. If left in the water, the armed rollergun sinks slowly and horizontally while if you remove the shaft it floats vertically.
The shooting accuracy is impressive from both 3 and 5 meters and requires no aiming compensation, in other words you don’t need to aim at a higher o lower point to hit the centre. Recoil exists and there is no doubt about it but it has a moderate intensity and it is easily manageable considering that it is a roller equipped with 17mm reactive bands.
Like all rollerguns also this one requires a little longer to be recharged in comparison to a common speargun and for people like me who are not used to it can be "unpractical". In fact, once you shoot you need to release the rubber band from the second lower hook and only then you can slide the shaft into the mechanism (by passing the line in the proper spaces) because otherwise it won’t pass under the dyneema wishbone tensed against the muzzle. After that you should place the bands onto the first lower hook and then on the first pin of the shaft and finally stretch them at the maximum. In the video below you can see a part of the loading operation.
The line release tab tends to close even if the shaft is already housed in the mechanism and this might impede a fast re-armament in case of need. It should be remembered that with such a weapon it is essential to make at least two line loops along the barrel as it has a range of over 5 meters and keeping the clutch loose is not a valid palliative. A final mention goes to the special plastic bushings applied at the end of the bands that allow you to tie dyneema wishbones in a very simple way, definitely a viable alternative to the classical system with the flag knot.
A positive overall judgment leads me to endorse with enthusiasm this new design of the Portuguese firm Picasso.
