    Lately I’ve been thinking, I have read and heard that having 65% let off instead of 80% let off will give you more arrow speed, well I’ve wondered, is it possible to make a compound bow that has no let-off and would this give it more arrow speed. I know that the importance of arrow speed pales in comparison to accuracy but I’m just curious, I’m thinking a 45 lb draw compound bow without let-off of any kind could be extremely powerful if my theory is correct, I mean when we calculate kinetic energy we factor in the velocity of the arrow, so isn’t it safe to assume that a faster bow, as long as the arrow is correctly spined and heavy enough, is a more powerful bow? I want to hear feedback on this, personally, though I have bowhunted for only seven seasons I see no reason to need 80% let-off, my favorite bow that I ever used had only 50% let-off, it felt more comfortable when I released the arrow, even with the excitement of buck fever it was a piece of cake to draw. Maybe its just my hunting style but I feel that some people overexaggerate how long they need to hold their bow back for a shot. Here’s my shot sequence, see the deer, when he looks away, draw, anchor and then release. This is what has worked for me, but then again I do quite a bit of still hunting and stalking when the weather permits, you may only see a deer a moment, you need to make a decision quickly and commit to it, whereas in a treestand you may see a deer from a long way away before it comes into shooting range, I do stand hunt but I’m always hoping for rain, wind or a mixture of them so I can still hunt because that’s what I like better.

    Letoff is one of the benefits of a compound bow. If you dont want letoff why not just shoot a traditional bow? I would bet that with no letoff, your accuracy would decline considerably and you would not be able to hold it for very long IMO.

    To be honest I dont even know if it would be possible.

    I am pretty sure, all things equal let-off does not affect FPS but does affect the forgiveness of a bow. And to not have any let-off why not buy a longbow or recurve that you can put sights on.

    :D We used to shoot 30% let off bows that shot a smokin 190…thats one ninety …FPS…so that theory is faulty :^O

    some do find a smoother relese with lower let offs making them personally better shooters..

    Isn’t the Genesis essentially what you’re describing? And wasn’t the Fin and Feather cam almost a no let-off?

    It didn’t stick around very long, so I can only assume that there wasn’t much of a market for it.

    That’s right.

    I’m not going to do all that work not to be rewarded with a little letoff on the back end.

    I might need a memory adjustment but If I recall these are touted as being able to shoot from various lengths of draw. What I mean is you can come to a half draw and release with no problems. Other bows are suppossed to be released from full draw. Something about quick shots while bow fishing or bird hunting etc where you need quick instinctive shots.

    Anyway, I think thats it.

    They have been around for years, they are called recurves. :^O
