    I bought a new crank machine and need to buy a tension calibrator.
    Which brands/products are reliable and worth recommending?
    I've read a few threads stating the Gamma calibrator or analog tension calibrators aren't that reliable and should go with a digital fish scale. Does analog/digital really make that much of a difference?

    I have the gamma and it's off by 3lb. The alpha is right on and came with the alpha axis pro model.

    I have an ultrasport50, which I purchased from a well known stringing site. It is pretty easy to trust this scale, and it wasn't that expensive.

    Ditto on the Ultrasport 50. It's said to be very popular with stringers. I have one, too, and would recommend it. I think digital scales are more accurate, has more bells and whistles, and they calibrate themselves automatically, as opposed to analog scales having to be manually calibrated. And they don't cost that much more.

    I bought the Berkley digital fish scale at Walmart for ~$20 after reading good reviews on it in the forums. So far it works great.

    My only criticisms are that 1. it uses more expensive watch-type batteries instead of AAs or AAAs and 2. it doesn't have an auto power-off feature so you might accidentally leave it on and run down the batteries.

    the calibrators are adjustable if you want to make it match your alpha. you have to remove the end w/o the scale in it and then you can adjust the nut (or nuts) to change the tension. please make sure you are using a reliable weight other it will create a lot of other problems.
