Rytera is a division of Martin Archery started by Ryan and Terry Martin to.....well here's a quote from Martin's forum
'As many of you know I have been designing compound bows since the introduction of the original design in the early 1970’s. It has been a challenging adventure from Dynabo, 4 wheelers, 2 wheelers, Onza, Cougar Magnum, Lynx, Jaguar, Scepter and others. I enjoy designing and now have my son Ryan working with me as well as the best design team ever in my opinion. As anyone knows that is in the manufacturing of bows it is a lot of work but can be a fun and challenging adventure. It is not all about profit but rather the challenge of making the best bow. Maybe that is a part of why we have been producing product for over 55 years.
The new Rytera bows are a separate product line of "Elite" series Pro shop compounds and are not part of Martin Pro series, Gold series or the traditional bows. The new Rytera will have two models or 2006 each very different from the other.'
So you are basically buying a Martin with the Bullet X, it's priced along side Martins Pro Series bows rather than being a budget line on it's own.
