Formerly known as the ProPositioner, the Compass is an indexing device for single-lance tube cleaning with AutoBox ABX-PRO (ProDrive).

Designed for quick set-up, the Compass delivers accurate tube-to-tube positioning in horizontal, vertical, and enclosed heat exchanger bundles, offering portability and versatility at a cost-effective price.
