CTM,you have to pay closer attention!The first guage(which I have,and like)measures to 1/1000's.The second guage is only measured in 1/10's!This is a big difference in the ability to get the most from a good cartridge!Though the ability to measure to 1/100's is all we really need,so the extra range of guage #1 is a bonus.
Best!
Best!
