    Question Martin Onza III Question....

    The Martin Onza III lists its longest draw length @ 30.5". Does anyone know if this is a long 30.5" or a dead nuts 30.5" and hopefully not a short 30.5"?

    Well, that's an interesting question... Before I bought my Onza, I emailed Martin to see if their listed specs were AMO draw or tru draw, and they said that all their specs are AMO. That being said, the shortest draw (per spec) should be 27.5" AMO. My AMO draw is 28.25", and I am on the shortest setting. So 3/4" off. So it would go with out saying that all things being equal, it should make the 30.5" max draw would then be 31.25... Hope that helps. Maybe if anyone else has had a similar experience with the bow they could chime in too...

    That is exactly the info I am looking for as I wanted to know if my 30.75" draw could find itself in the Onza III. Thanks.

    Thumbs up Thanks for the response...

    1/2-3/4 over I can deal with which is what I was hoping for. That means this is another possible for a new bow.

Even if exact a little string tweaking would give you your draw length. Twist cables and untwist bow to lengthen. Just maintain ata and all will be well.
    sounds about right. I did get mine down to the same, but it dropped the weight to under 70, and I didn't want to play with the cables anymore, so I put it back. I wasn't worried about the 1/4" lol.

    Huh, the bows I've played with if the shooting string was long, the poundage went up. If I short-strung them, the poundage went down. When I was setting up the Onza (first dual cam I've played with) it came with the ATA at 33 3/4, and the BH was 7", and the DL was long. As I cranked the cables down to bring the ATA down, DL and BH increased (slightly), and the poundage went up. Shortened the string to bring DL down to spec, and the poundage went down. It ended up being a balancing act! At the end, my ATA, BH, and poundage were dead on, and the DL was a little long...

    I shop the internet, mostly Ebay and various sports or archery online dealers. I make a note a bows I would like to purchase and do to my budget I wait a few years and then scoop something up. My latest purchase was a brand new eight year old bow...LOL a Cougar 3 Magnum. It was in mint condition, never had been setup, and now I know why. The specs are all over the place. Now I have just decided to set the BH and DL where I want it and let everything else be what it wants to be.

    Being that it sat for eight years I completely dismantled it cleaned the axles and sanded the cam grooves, replaced the strings and cable and pretty much have a brand new never been shot bow until I put a few arrows through it. It shows promise as a real tack driver.

    I am looking at the Onza III, the Ridge Hunter and or the Firecat 360 in the Martin line-up but if God is willing hopefully a Rytera Seeker 365 would find me.
