well at my proshop i got my bow setup with a string loop...well i had my prong style rest on at the time....well i took off my prong style rest and put on a whisker biscuit........i tried to get my arrow level with the loop to the rest......would you just put a small level on the arrow at full draw to see if your string loop and arrow rest are lined up to make the arrow lined up straight.....i'm still learning about bowhunting.....so try to understand what i'm saying on this one...

If you replaced your prong rest with the whisker by yourself and you do not have a bow square, take it back to the pro shop and have them align your new rest for you. I used a whisker bisquit when I first started shooting and I loved it. The arrow didn't fall off the rest in any position but mostly during the draw. The loop is easily adjustable (well almost) by sliding it up or down on the string. Good luck enjoy .

If you are in this hobby to stay. Purchase some tools. I don't recommend buying a regular bow square. I would buy a BPE square. You simply screw an arrow on the end and you have a square. They are often hard to find and cost about 4 bucks. Your initial placement may change while you tune so don't be really set on a nock height. My nock is always low. If you don't have a way to tune(This include nock height) reply and i will tell you how i tune. It is complicated but it is better then any other way.

i'm in this to stay i love bowhunting i took my first bowkill this past fall....
