I thought I would pass on some of the experiences with a few relatively new (at least to me) bow maintenance tools that are currently on the market. I have only started using these within the last month so take my experiences "with a grain of salt".
The first two devices I have not really seen in any of the pro shops I frequent. I first saw both of them, or something similar, when I stopped down at Len's this past summer. They are a bow vice and the R.S. level combo.
The bow vice pictured above is the one that was most readily available to me and which I purchased. It makes setting up and working on a bow quite easy. It also saves alot of counter space which can be utilized for other equipment/items.
The R.S. levels work in tandem with the bow vice to allow you to setup your arrow in a perfectly perpendicular position to the bowstring. One level clips on the bowstring itself while the other clips onto the arrow. There is a third level which is part of the string unit and it can be utilized to check the balance of a sight level.
Last but not least we have the EZE laser center shot tool.
I read an article about it in Petersens a few months back and decided to give it a try. It is extremely easy to use. You have to remove your sight from your bow and then mount the laser tool in the sight mounting holes via some thumb screws. Then simply adjust the laser so it intersects the string right where the arrow is nocked. You then rotate the laser beam forward to make sure your arrow is in a straight line with the bowstring.
Some great tools and not really that expensive when you consider some of the time and frustration they can save.
Please feel free to add any further tools or suggestions that you have also found to be worthwhile.
