My buddy and I both have that same scale. His scale and mine are 4 pounds different on the same bowYork barbell weights can easily a few pounds off.
I’ve had good luck with these and recommend to everyone and they always get good feedback. Cheap enough if you lose it or damage it no big deal. Weighing recurves up to 50# so far. I’ve read some mixed reviews for compounds but do t have any experience. I have 3 and they are all within .2lbs. Probably user error.
First one I’ve been using for over a year same batteries. I use it all the time.
