How in the world does one install the modules necessary for draw length? I am new to compound archery, and just purchased the Martin Threshold Adventure from Sportsmansguide.com. The bow kit came in pieces, with no discernible manual for assembly. Please, anyone out there. How can I do the work myself, without having to pay a tech at an archery shop.

i know nothing about that bow,but here is a link to the 2011 bow manual.http://www.martinarchery.com/manuals/2011_Martin_Compound_Manual.pdf..please post pics of your bow and all areas of the bow you have questions about.im unsure what you meen when you say it came in peices.is the bow all torn down as in you need to put the whole thing together of are you just needing to change out a mod to set your dl(draw length).so post pics please to better help you in what you need.oh ya and welcome to the martin tech family.....do you know how to mesure your DL.and it really ez to change out a mod on a single cam bow.ther are 2 screws holding the mod in place.remove the 2 screws and the remove the mod and then put the mod you want back in the place of the last mod.tighten screws down.if one screw is coverd by the limb then pull back on the cable with your hand(dont draw the bow) and it will give you enough room to take that srew out.

I would doubt that it is that much different than the accutrak. If you look at the lower cam, there will be a section that the string is NOT touching when at rest, but when you draw the bow, it bottoms out against that portion. If it IS indeed like the accutrak cam, you just have to take two small screws out and put in a different module. The THICKER the cam module, the less draw length, the thinner it is provides a greater draw length. If it is typical of Martin, you will have them number 1-6. And each one represents one inch incriments.... I see it goes from 25-30 inches, so more than likely a #1 module is for 25'', 2 for 26'', 3 for 27'', 4 for 28'', 5 for 29'' and 6 for 30'' and there is a stopper that hits the limb when you are at full draw, this cam be moved the adjust for incriments smaller than one inch. Soooo if you need a 27 1/2'' draw you use cam module #4 and back that stopper off halfway.... This is just a general idea of the process, but I hope it helps!

Changing a module is the same for all Martin single cams. There are 7 modules in all, and usually one isn't used for a particular bow.

That sucks! Looks like they changed to a Martin looking cam 2011.

I haven't seen a 2011 Threshold, but looking at the bottom cam in the 2011 catalog and cross referencing it it appears to be a 2008 MPro cam. Wonder if it has the draw stop. Can't tell from the 2011 catalog. This is just a guess on my part but I'll bet Martin is using up some stock of older cams they have. If such is the case then any manual showing the MPro or M2Pro should be applicable.
