The difference is in selectable detend interval stops: 6, 8, 30 stops towards 6, 8, 10 stops. These are levelers with built in rotator.
For your combination you should get EZ-Leveller II. This is a leveler on its own without built in rotator. But, I can not find it on e store anymore since the new website is started. I hope it will not be discontinued.!!??
