SIGALSUB: EVOLUTION PRO SHAFTS 

AND ENERGY WISHBONES

OUTSTANDING PERFORMANCES


 

Sigal shafts are already well-known in the market for materials high quality and for the accurate production processes but with the 2011 product series the company made the difference. I had the pleasure to test a 130cm evolution pro shaft that in term of quality and technology has no equal on the market.

One of the main features of this series is represented by the position of the hooking points. The first is placed 65mm from the very bottom of the shaft and the second one 40mm from the first.

This might not ring any bell but try to think that in most of the cases the release mechanism box and the first hooking point are only one thumb width away from each other! Furthermore the shortest shafts have a third hooking point to make loading easier instead from the measure 140cm on they are provided with four of them.

Another important feature characterizing these shafts is represented by the introduction of the new diameter 6.75mm produced as well as the other classic diameters. This intermediate measure represents a good compromise between strength and easy handling that allowed me, together with the special position of the tips, to increase the power of the bands providing then a very powerful and precise shoot with a 95cm wooden railgun and no effect on the brandish.

With Evolution shafts, at first sight, it is possible to note there is like a light grey coating. That is the outcome of a thermal process making the Sandvik steel 10% stronger than before, getting a 52/53hrc hardness level! 

In addition new 1.2mm steel barbs, edges and holes smoothed and hydrodynamic lowered tips would already make this product outstanding but for Simone Gallini this was not enough and together with BLUWORLD technicians designed and created a new tri-cut tip.


The EVOLUTION PRO series is in fact provided with a tricuspid tip where each cut is concave and it ends with a little tab on top. It looks like a screwdriver but it ensures a high penetration performance when it hits the fish as the tip goes through the flesh with no friction thanks right to its concave surfaces and its very sharp edges…just like some Japanese knives where the food does not adhere to.


The shaft well endures the impact with rocks (better avoiding it anyway) and in most of the cases it only loses the little tab on the top. Thanks to its stiffness and its spring backup the shaft trajectory is linear with no flickering. They are not really cheap but the higher price can be reasonably compared to the higher quality as they cannot be considered a common product. 


Among the other accessories presented this year by SIGAL and that deserve a special mention there is the ENERGY wishbone series. Three models XL, Jewel and Wire are all made in titanium.


The main advantage of the use of this material is represented by the reduced weight. By taking a look at the table below you can note that the standard wishbone weight gets about 50% reduced, a very important feature in relation to the general arrangement of the railgun.

 

Furthermore, all the weight subtracted to the wishbones turns into a greater power on the shaft and produces les noise. By testing these wishbones I could agree with the producers who suggest the combined use of XL and JEWEL on a double band railguns as mine.


At first I was doubtful since I am used to dyneema wishbones but then I realized that thanks to the different width (4cm for XL and 3.2 for Jewel) the bands stay parallel with no narrowings like when you use dyneema wishbones and in my opinion the shot is more fluid.


Then the only fault these products have is that you get addicted to them and when you use other ones you see the difference!
