Martin is now more than 60 years old company that has been making also compound bows for tens of years. I find it somehow disturbing that the production models now include this kind of simple and downright stupid flaw that is eating the cables if not fixed (depending on tolerances in manufacturing, but clearly the whole issue could be avoided altogether). In comparison, I had a closer look at the draw length modules of my 2003 Martin Phantom II bow: both inner edges of the module groove are round, not square and sharp as is the case in Nitro cam module's inner wall. It just does not make any sense to me. They clearly know how to make such a simple thing right, so why on earth they don't do it right in their 60th anniversary models such as the Onza 3 bow?
If this is a cost issue, it certainly is saving in a wrong place. Great bows otherwise, why ruin it with such a minor detail done wrong? And because the same cams are used in several models, also the issue must be spread over a great portion of the entire lineup. I would expect to see the same thing with Rytera Hybrix cams as they are basically the same cam, aren't they? This kind of helps me with my irrational desire of purchasing a Rytera Nemesis to my "collection"
Don't get me wrong. I like my Onza 3 enough to replace my Hoyt with it. I fixed the issue by making the edges round with a file as explained above in a previous post. But somehow, for some reason, I feel sympathy for this company and I would hope it to succeed even better in the future. Therefore it makes me sad that with all the potential and value for money with these bows there seems to be insufficient attention to detail. Things being like this, I cannot really full-heartedly recommend Martin bows to others, as much as I like mine.
That being said, there are issues to be improved with other manufacturers, too. For example, it is a common issue with Hoyt bows to make some noise from the limb pockets when drawn. I have experienced that too with my CRX 32 (although you can usually get rid of that by just ajusting the draw length bolts back and forth a few times. For a permanent fix, you may need to disassemble the bow and add lithium grease to limb pockets). Does not really give an impression of quality in a hunting bow that should be as quiet as possible. I also feel that the draw cycle of the CRX is poorly designed: transition to let-off is abrupt and the valley too short. I believe the new RKT cams have not made any significant improvement (by comparing the draw cycle curves, they are very identical). Martin's Nitro cams are much better but the modules need a simple fix. This should be done by the factory, not by bow owners. This is the way to improve trust of the customers and helps in building a good quality reputation.
