I have an older tac 20 that was used on a mod. It's a 2 stage with a car sling that's seems like it's not the typical one used. The removable brackets on top of the styles are longer making the crosshead higher. I know this was engineered to create more rise. The jack sync sensors are the optical type , not the magnets like on newer tac 32's. I've tried to set up the jack RESYNC time but it seems as this feature was not on this older version of software? , and I'm guessing this unit will only RESYNC when the sensors see its out of sync. And of course the previous service company has taped up the sensors after a few went bad so it never resync's. I'm going to replace the sensors but I'm I right about the older version not having a feature to auto resync at a set time?
