hello fellow archer people....as my handle states, i am very very new to archery and bowhunting....
i have millions of questions but we will take it one at a time...my first bow ... PSE nova , 28 inch draw 65 lbs..what does it mean when it says on the spec sheet ..eff. let off = 55% and actual let off = 60%
.............also ........ cbl/str 50/51.00 ... are those lengths......all advice welcomed and appreciated...[&:].

Welcome to the forums! The letoff is the percentage you hold back at full draw.

percentage you hold back at full draw. .....what does that mean...............i am that green.....sorry.

When you draw back all the way, letoff takes effect. Letoff is best described as a decrease in the weight you hold. When you draw all of the way back you will notice that you are holding less weight. This is letoff. If you have 80% letoff you will hold less weight than a bow with 50% letoff. A 100 pound bow with 80% letoff will mean you will hold back 20 pounds at full draw. A 50% letoff bow at 100 pounds will mean you hold back 50 lbs.

zak is correct. When the cams roll over, after they load the limbs with their peak weight, they break over and the weight drops. 65% letoff means you are holding 35% of the peak weight.

You say that like it is a shock!

Not to pick on you Zak, but you should have said the percentage you are not holding at fulldraw. Not to often I get to pick on someone about their english.

Uh.....well...uh..first time for everything??? LOL.......[8D][8D][&:]

thank you all ..........i now understand ya'll will be seeing alot of me and my questions........again thanks
