I have two of these scales. The light gray colored one I have measured against a known excact weight so I know it is correct. The black one is another story. Yesterday I checked a bow and the gray one showed 52,5 pounds. The black one showed 51,2. They were both drawn to exactly the same lengt, not drawn by hand. Things like that really pi- - me off. They do not cost much,but still.

That is why it has a :) on the front of both so it doesn't P you off so much :laughing:

I see :laughing: :laughing:

Quite honestly....you would be hard pressed being able to notice that much difference drawing the bow. I have been using the same X Spot scales for 15 years and never once had any complaints on accuracy of draw weight. I have had to replace one after dropping it too many times though.
BTW.... These scales do NOT work well for fishing scales. once they get wet a few times they rust up and puke fairly quickly...
But..... If you want something a bit more accurate... Here ya go....

Kirk, I agree, but when shooting through chronographs testing for speed with a certain arrow weight I want a correct draw weight, in order to measure the accurate arrow speed. Maybe I am a bit hung up on accuracy, but thats the way I am.

Bue, I had the same smiley face scale a yours. I don’t remember whether it broke or if it just wasn’t accurate, but I replaced it with this:

This scale is accurate and durable.

I understand completely….But If you are using the same scale to compare one bow to another, these scales work just fine… Even if you were testing different bows for the public…. They still work just fine as long as you use the same scale all the time.
but you may want to upgrade to a certified scale with a higher degree of accuracy that can be calibrated with a certified weight.
Testing bows accurately for your own data references just requires consistency.
Testing bows accurately for the public will always be contested no matter how consistent you are. Even using two chronographs in tandem, with infrared light kits indoors, a certified scale, a good shooting machine, and matching GPP on your arrows perfectly… your results will still be considered skewed, and contested by the public…. I finally gave up the effort myself…
I tell my customers to go shoot the bow I just built them side by side with a comparable draw weight bow at 40-50 yards and see which arrow is in the dirt or the target…. That will tell the tale real quickly….
