Does anyone know the original draw length on the 2005 Martin Orion? A friend just gave me this bow and it has the basic manual but not too much else

It depends on what cam is on the bow. Dynacam (single) is 26 to 30". This is determined by a module, numbered F1 through F7, F1 being the shortest. Each number up increases it by one inch.

If it's the TruArc cam then it's determined by a rotating module, starting at 24" up to 30 1/2". There were two size TruArc cams made, small and large. You'll need to know this, but suffice it to say that if the draw length goes to 30" it has the large one. Small cam only went up to 27".

You can find further information on Martin's home website. Look for the model number, M83. Look under "tech info".
