Magnetic Pressure Buttons
Having been a bit disillusioned with the Beiter pressure button - old technology and very expensive and for me not the best solution. For barebow you need a button where you can easily change pressure for different distances. Yes you can do this with the Beiter but there are so many variances with the different springs and so on so I decided to try magnetic. I Looked for info or reviews on these but found they were non-existent, so if you're thinking about one hope this helps you decide.
I would like to try the Wilfer button but the price is just ridiculous. So I’ve tried the Jet EXE, the Gabriel Little MUCK (cheapest of their range of magnetic buttons) and the Arc Systeme Pro Magnetic.
They are all really simple to use. Set the centre shot and then simply turn the body in or out to change tension. It’s completely linear as it’s simply two opposing magnetics. I’ve read various technical treatises on how differently a spring and an opposing magnetic system worked but in the real world I found that it was really easy to judge the amount of tension required for a particular distance. No changing of springs needed so much simpler to tune - for me anyway - I’m sure there are lots of Beiter afficienardos who will disagree.
I started with the EXE Jet which is the cheapest. I really liked it so I bought another one so I could keep one for with centre shot set for indoor and one for outdoor. Unfortunately on one of them the barrel broke after a couple of weeks so I sent it back and decided to try the Arc Systeme Pro. This is really nice quality and I really liked the titanium tip. When I got the refund for the EXE I bought the Little MUCK from Gabriel (of BiDrop fame in Germany). This is again a lovely bit of engineering, quite small by comparison. Main difference with this one is that there is no click on the adjustment but in practice I haven't found this to be a problem.
I would say that both the Arc Systeme Pro and Little MUCK are better than the EXE Jet both in terms of quality of engineering, materials and components. Use wise all much the same. I prefer a click in the adjustment but don’t find it an issue when it's not there. None of them came with any instructions as to how you change the tip. The Arc Systeme has a different tip for ali arrows and the Little MUCK a spare. I bullied some instructions out of Arc Systeme (eventually) but it’s pretty obvious how you do it with the LM.
Having tried various spring buttons (my opinion obviously) is that the linear nature of the progressive increment in pressure makes them a better choice - for barebow anyway. Most will disagree I’m sure!
