Just setting up my new bow but a little confused. It says it goes down to 25" draw but the tech chart says #1 on the module will set it at 26.5" minimum. I have it on the #1 but curious what length that is.

The chart I saw says 25.5" min. DL. Hmmmm.... If you can, measure it from the apex of the string to the deepest part of the grip, and add 1.75".

Arrow splitter is correct that you can just measure, but remember that the draw stop really sets you draw length and the draw module adjusts how much of a letoff or valley that you will have. If you move the draw stop further to the negative you will get a shorter draw. Once you get used to these cams you will realize that they so adjustable and you can set them up to shoot to your shooting style.

This is the chart I was looking at.

So I could bottom out the draw stop for minimum draw length but still put the module at 2.5 for 28" and just have a 26 draw but a huge wall?

Think of it this way. If you have it set for a 28" DL, and just draw until you reach 26", the cams will not have fully rotated, and you'll be holding more of the weight. This is exactly what will happen if you set the draw stop to stop the cams at 26" with the mod set for 28".

That would explain why the guy that set it up said there was no adjusting the let off but the tech from Martin said the bow is 65-80% let off. I called Martin to find out why the specs had variable OBO speeds from 325-345, he said 345 was the 65% left off and 325 was 80%.

I have it set at the far negative on the draw stop to get 26" draw then on the 1 module. Doesn't seem to be much of a wall on it. Good for speed, bad for arm muscles if the deer wants a long stare down!

you could put some twists in the string and take a couple out of the cables then open up your draw stop

May need to find a good shop here in AZ that deals with Martin and get it tuned for me. Initial set up was at Sportman's Warehouse...nice people and set up was free but think an archery shop would be able to fine tune a little better.

Depending on where you live you could probably find a really great tuner such as Crackers on Archery Talk. Also if the bow is just unusable and twisting the bowstring doesn't shorten the draw enough, you may be able to have someone that knows what they are doing short string the bow. Hutch who is a member here can probably help you out he makes high quality bowstrings and would have a good idea how much you could make up by short stringing the bow.

The 25.5" DL would have been attained with the Nitro 1.5 cams, which are the short draw version of the Nitro 2.0 cams. I'm pretty certain the DL range on the 2.0's is 27.5-30.5 while the 1.5's go 25.5-28.5", and those DL's would be with the stop set for 80% letoff.

It is useable now, don't think I need twisting, just someone to tweak it to maximize speed but hopefully give a little wall. I have the draw stop at the furthest negative and the module set at 1 which by the chart listed is 26.5". I need to find someone to measure so I can see what the actual DL is. The DL is good but it seems at full draw the wall is very short and just the slightest give and it is trying to pull forward.

This is what has me confused....the chart posted prior shows 26.5" as the minimum. I have heard 27.5" before as the spec but then another posted they read 25.5" as the minimum. I understand there is a draw stop too but I would think the draw stop would have something to correspond to the module it is set at.

I think that you are overthinking it. If you want more letoff and want a little more valley just move the stop slightly to the positive. When you do that the drawlength will stretch a little. It really doesn't matter what your actual draw length is as long as you are comfortable and that it works for your shooting style. For me I don't like a deep valley and don't like alot of let off -- it seems to keep me honest and makes the bow faster.

Probably true. I need to read more on bows and how they work I suppose. To me if minimum DL is 27" then when the cam is set to that module then 27" should be the shortest full draw possible. Simple!

I would think numbers on the stop would make more sense for setting draw length than having multiple charts with different numbers the module is suppose to be at to get a specific draw length.

Donamese,

You have to think about the stroke of the cams being limited by the draw stop. It doesn't really matter what module setting you set it on for the draw length besides over rotating the cam past the flat. For the draw length that works for me is pretty close to 30.5", when I shoot a Mathews with a 30" module I feel a little cramped. On my Martin bows with the Nitro cams I simply pull the bow back to full draw and get into the anchor, and continue to adjust the stop until I feel like I can use my back muscles to support my bow arm while it is relaxed. When I feel that I have the stop really close, I set the module up or down to get the amount of let off or holding weight that I like. For me I like the bow to pull all the way back into the stop and the bow lets off right at the end, in fact the valley is very small. This way it forces me to pay attention and to immediately use back tension. My son on the other hand likes the feel of a very deep valley and likes having very low holding weight. When I try to shoot his bow it feels like I have to practically push the string forward to get the bow to fire. I like to use back tension with a thumb release when at full draw I get anchored pin the target and transfer weight from my index finger to my ring finger and pow the shot fires with a surprise release. With a huge amount of let off like my son's bow I don't release the shot as well. I love the simplicity and the adjustability of the Nitro cams. If anyone says that they don't like the feel of the draw cycle all you have to do is change the feel. They are a fantastic cam to use as a beginner archer because you can learn, tinker, and fine tune your shooting style without buying $100 modules.
