TunnelWatch® is a software-based tunnel controller written in a high-level programming language. There are three important advantages to this platform: First, it eliminates hard-to-understand codes and replaces them with normal, easyto-use, English commands. Second, upgrading your system is as easy as loading a new disk (just ask our POS customers.) Finally, this approach makes TunnelWatch capable of many features new to the carwash industry.
