Yes accurate homing as saved my arse many times along with "Run From Here".

Most of the cheap prox switches on Ebay either those Eddy suggested or the round bullet type with threaded body work well and are very repeatable. I mostly use the Round type has they are easier to mount and reach or fit into more places better.
