The Penobscot Indian bow named after the ingenious Penobscot Indians of the eastern woodlands. This Marvelous bow was one of the most versatile bows ever made and may have very well been one of the first compound designs ever built. The bow is stable and can be adjusted to a higher draw weight by tightening the back strings. The back bow and strings help reduce string follow adding speed. This bow also sports lower hand shock as well as accuracy. This bow featured a Elliptical main bow which also adds to speed.

This is an excellent bow with a super sweet draw!

To adjust the draw weight simply put the bow on a bench with each tip set on a 1" thick block of wood. Now clamp the handle down to the bench bending the limbs slightly backward. This will relieve the string pressure. Take the old string off and twist it 2 -3 turns tighter. Unclamp bow and replace 1" block with a 2" block, Reclamp handle down and replace the string. The draw weight will increase. Use up to a 4" inch block. The tighter the back strings the higher the draw weight of the entire bow. Piece of cake!!

    Hard hitting longbow! Love it!

    At first I was a bit aggravated trying to get a consistent setup among the three strings. After coming up with my own system, it is super consistent and one of the great benefits of this bow you will learn is that the brace height does not drift over a few hours because of the tension between the three strings once set up properly. I have a 55-60 pound Penobscot. The best setup for my shooting style and this bow is a 7 1/8" brace height. In order to obtain this and have the same performance each time, I set the belly bow string to an initial brace height of 7 5/8" and then nock the back bow strings at the belly bow tips and continue to evenly tighten the two shorter back bow strings one at a time, squeezing the back bow tips toward the belly bow to wrap the string over the back bow string nocks until I have drawn the belly bow's brace height down to 7 1/8". (make sure the smaller back bow strings rides over the front beveled edge back bow limb tips) You would have to figure out what is the proper height for you, but hopefully this method helps some out as there isn't much info or demonstrations out there about this part of it.

    What I love about this bow after shooting it for a while, is you will notice the first part of the draw seems very easy and the last 1/3 of the draw tightens up. Although I haven't chronographed my arrows to compare, I know it is launching the same arrows much faster than my other 55-60lb bows simply based on the depth the arrows are driven into the same target and the difference in the gap I use for the same distance when aiming. For those of you that make your own strings, this bow takes a 67" belly bow string and the two back bow strings are 19". (I ended up putting river otter silencers on all three just because of the way it looks, although the belly bow string really benefits from it). I love how this bow draws, shoots, and the fact the brace height holds after a long period of time being strung and shooting. You won't be disappointed with a Penobscot! Great job, Grayvn!
