Ok here is the first part of my review
heres a couple of pics of what it looks like.
here's a rough translation of the instructions
principle of adjustment vaulted lay out D an adjustment of exit of your short prop has ugly L nut (N 8) after loosening of against screw (N 15). a simple adjustment of hardness s' carry out by means of L nut (N 5) after loosening of serrated roller (N 12) On this model the system dopposition of the magnets makes it possible to cover a sufficiently large beach without any disassembling we propose to you in more dune head titanium, a plastic head better adaptee for the arrows aluminum attention not to tighten the plastic head with the key! first magnetic shepherd in the world, head titanium, system patents. burger magnetic (race of 2mm) pressure (gr.) adjustment (24th of inch) burger arises (race of 2mm) pressure (gr.) adjustment (24th of inch)
It is a very simple button to use. 1 rotation of the big magnet is broken down into 10 clicks so from max pressure to min pressure is 70 clicks this is locked with a thumb screw. The locking ring has an O-ring to go against the riser and they provide a threaded bar so it can be locked tight against the riser also to note there are 2 holes in the locking ring 1 for the grub screw and one for the threaded bar. To attach the titainium head they provide a couple of small tommy bars so this can be secured tight as well and it's ok for carbon arrows, But the plastic head is for aluiminum arrows. Although I like to use plastic for my Navs.
Having had a good look at this button now I can say it is well made and finished. There has been alot of thought gone it to the design addressing the small niggles that other buttons have.
It is easy to set up if you have your old button already set just press it plunger to plunger to the the arc systeme button and adjust the tension on it so that both buttons compress at the same time with no springs to change this is very quick. it has a scale on it so you can record the settings, It should not be prone to rust that another well known button does. also easy to lock to the riser with tools provided.
I will report later on use and if it will fit my
shibuya rest but I think it will be fine.
But even before I get to shoot with it on paper it looks alot better then the
Shibuya DX but the price does have to be taken into consideration when making these kind of comparisons.
