Smart holiday detector

A holiday detector system comprising:

• a holiday detector apparatus comprising:
• a housing comprising holiday inspection circuitry to perform holiday inspection on a surface;
• and
• a probe extending from the housing for surface inspection, the probe electrically coupled to the holiday inspection circuitry;
• a graphical user interface device electrically coupled to the holiday detector apparatus, wherein the graphical user interface device comprises a module interface for connecting modular accessories to the graphical user interface device by a wired or by a wireless connection, and wherein the graphical user interface device comprises a display screen and circuitry to:
• receive holiday inspection signals from the holiday detector apparatus, wherein the holiday inspection signals comprise auditory signals representing holiday inspection analysis data from the holiday inspection;
• generate digital data representative of the holiday inspection signals;
• format the digital data into a graphical representation of the holiday inspection signals;
• display the graphical representation of the holiday inspection signals on the display screen;
• and
• digitally store the digital data in a data storage device;
• and,
• an encoded wheel mechanically coupled to the holiday detector apparatus and communicably coupled to the graphical user interface device through the module interface, wherein the encoded wheel is configured with rotational tracking data to determine a distance traveled, and wherein the graphical user interface device comprises logic and circuitry to receive movement data from the encoded wheel and to determine a distance travelled by the holiday detector apparatus based on movement data received from the encoded wheel.
