View Full Version : What's the AMO on a martin jaguar take-down bow?

Martin's website lists two AMOs for the jaguar take-down: 60" and 62" although the 60" AMO is on a current listing.

I bought a 60" AMO string (16st) to put on it but the brace height was 8.5" which is 1.5" over the recommended brace height. I'm going to buy a 62" AMO string to see if it fits but all the current listings for the bow say it has a 60" AMO and I bought it a month ago at Bass Pro Shops. Did they sell me an old bow? They didn't give me a bowstringer with the bow either.

Any idea why this is?

Actual length from tip to tip is 58.5"
Actual length of factory string is 57" (after a month of use)
Actual length of replacement string I got is 55.5" (60" AMO)

When you measureed the bow did you follow the curves keeping the tape in contact with the bow or did you measure tip to tip in a straight line? From the number highlighted above ( in blue ) it would seem that your bow is actually a 62" bow and your string should be 56". Are'nt there any specs marked on the bow?

I measured tip to tip in a straight line.

The bottom limb says @ 28" #50 but nothing about AMO length on either limb.

I wonder where Bass Pro Shops got this bow...

I doubt that things have changed much, but a standard length for string on traditional gear has always been 3" less than the length of the bow. In other words, of your bow is 60" the string should be 57" if you're going with a standard setup.

My best guess from what you've posted is that the replacement string you bought was either put in the wrong packaging or the packaging is mismarked. If you're measuring 55.5 it's plainly too short.

Some people like to play around with different brace heights so may change the string and go 1/2" longer or shorter, depending on what they're trying to do, but 57" is the suggested length you need. However, note that the packaging should be marked 60" AMO. When you return that one or just buy another one I would suggest you have it measured before you leave the store.

If I may be sold bold, may I ask why you are replacing the factory string?

I bought the string on amazon. I'm going to buy a 62" amo from the same seller and see if it fits but I need a string next week so I'm going to hunt for one in person.

The factory string's serving started coming undone pretty quickly and the string frayed.

Here's the guy who makes my recurves strings, makes the string any way you want them, whatever length, in 32 colors for under $12 to your door.And he's quick as well, each order has taken less than 4 days till I was stringing the bow with the new string. Give him a try. :)

I went to an archery shop today and got a string

The string I bought on amazon was made by "October Mountain" and it was 60 amo and made by bow have an 8.5" brace height.

I tried a 60 amo string today made by "Stone Mountain" and it made my bow have an 8" brace height. They had a factory Martin string there but couldn't sell it to me since it went with the martin bow they had. This string made my bow have a 6.5" brace height. I then tried a 62 amo Stone Mountain string and it made my bow have a 6.5" brace height.

In short, the non-factory string needed to be 62 amo while the factory string was 60 amo.

Do you know what string material they are using? Reason I asked is Bcy B-50 stretches a lot. B-55 stretches about the same. Dynaflite 97 stretches less. The point I am making is each one made at the same length is going to be a different length on the bow. Changing the brace height. So depending on the string material it's going to change the out come.

You do know you can twist or untwist to change the BH of your bow to find the best Bh for your bow. Just make sure you you don't untwist too much that you unravel the end. You should have measured that factory string at the shop off the bow. Go to recurves.com and talk to chad if you want quality strings. If your still not sure.....Just call Martin Customer support and they will let you know what length strings to buy.

The October Mountain string was supposed to be B50 and the Stone Mountain string package is marked D97.

I'm not sure what the factory string was.

A Traditional string usually has 10 to 12 twists in it. It can have up to 20 and no less then 10. To get the desired brace height you need to untwist your string.

It's hard to untwist an untwisted string! The 8" BH strings were untwisted when I put them on.

I did put the factory string on my bow and it made my bow have a 6.5" brace height.

I think the point of this thread is that different manufacturers make strings different lengths even though they say their string matches the AMO standard.

Most string builders know that traditional strings are built 3.5" shorter then what the bow is marked. If I built you 3 strings the same, one out of B55 one out of B50 and the last out of dyna 97 your bh for all of them would vary. Now if you have a string the maker made out of 452x then I hope you have reinforced tips. The material on most recurves is stretchy to take up the rebound of the limbs. If you have a untwisted string they didn't know what they were doing! The strands of string material needs to bundled together to work properly. Take a look at this link http://www.mac.asn.au/string_making.htm it explains bow strings and trad strings. Now if you want a bow string that gives a 6.5 brace height you need to have someone one build you one with the right material and length.

One thing I forgot you need to do is order a string a 1/4" longer so you can untwist and twist if needed.
