Abstract

Locate information relating to use of a locate device to perform a locate operation may be acquired from one or more input devices, logged/stored in local memory of a locate device, formatted in various manners, processed and/or analyzed at the locate device itself, and/or transmitted to another device (e.g., a remote computer/server) for storage, processing and/or analysis. In one example, a locate device may include one or more environmental sensors and/or operational sensors, and the locate information may include environmental information and operational information derived from such sensors. Environmental and/or operational information may be used to control operation of the locate device, assess out-of-tolerance conditions in connection with use of the locate device, and/or provide alerts or other feedback. Additional enhancements are disclosed relating to improving the determination of a location (e.g., GPS coordinates) of a detecting tip of the locate device during use, a group/solo mode, and tactile functionality of a user interface.
