Question:

Could somebody explain "let off"to me, what is it exactly ?  I keep getting a garbled version at the local bow shop…thanks Mary

Response:

Let off is simple .. on a compound bow, there is a point when u draw back that it gets easier to draw. So let’s say for argument sake you have a 50 lbs compound bow with 80 percent let off. That means you are pulling harder and harder up to 50 lbs but when you get to full draw you should be holding 80& of 50lbs which is 10 lbs. Han Su Kim

Compound bows use all those fancy wheels and cables to give you a "mechanical advantage." Simply stated, the amount of force required to hold the bow at full draw is less than the actual peak weight of the bow. This reduced pounds of holding weight is called "let off". An example makes it easier to see. A 60 pound pull compound bow requires 60 pounds of pull to get back about half way, the weight of pull then drops down as the bow comes to full draw. A 60 pound bow with a 50% "let off" would only require 30 pounds of force to hold a full draw. Same 60 pound peak example with a 75% "let off" would require only 15 pounds of force to hold at full draw.

I think you meant you’d be holding 20% of 50 pounds with 80% letoff. Letoff is calculated as       Peak draw force – holding force in valley                                      Peak draw force for example, if peak force is 50 pounds, and holding force is 20 pounds,                                 50-20                                 —- x100  =  0.6 x 100 or 60%                                  50 There is a difference in AMO lettor and "effective" letoff, but I won’t get into that here.      Let us prey…..

Buy a copy of Bowhunting World and look at a bow review with the drawforce/length curve.  Years ago I bought a 100 lb spring scale that I hung from the basement ceiling to check bow weight.  You can also measure let off and get an idea of the mechanics for your bow. Frank

Response:

If the bow is 50# and has 50% let off, you will pull the bow back reaching 50# and then the cams will "break over" and you will be pulling 25#. If the bow is the right draw length for you it will break a little before you reach your anchor and you will be at full draw holding 25#. Email me if you need a more detailed explanation. – Hide quoted text — Show quoted text – >Could somebody explain "let off"to me, what is it exactly ?  I keep >getting a garbled version at the local bow shop…thanks Mary

does that mean up untill the cam’s "break over" you will be pulling the full weight.. ie: your pulling 50# then all the suddenly your only holding 25# while you aim, or with a 50% let off will you only feel like your accually holding half the weight? -Doc (yes its still me, new loggon though)

Has anyone been getting duplicates of this posting?  I have it and 10 other consecutive postings, that all keep coming up as new. – Hide quoted text — Show quoted text – >In real simple terms… If your bow is set at 50 lbs and you pull back >at a certain point the cam will make it feel like you are only pulling a >fraction of the 50 lbs according to the let off your cam provides. >I.E.   a 65% let off would mean that  a 50 lb bow at full draw would >feel like your are pulling a  16.5lb (+/-) pound bow.
