The SlideMinder Slope Monitoring & Warning System was developed in 2003 by engineers and geologists at the consulting firm Call & Nicholas Inc. to provide clients with a reliable, affordable, and easy-to-use slope monitoring alternative. 

Built in Tucson, Arizona, SlideMinders are deployed worldwide in a variety of diverse and often harsh conditions. Self-contained, self-charging, self-reporting and easily deployed, SlideMinders gather and report critical displacement data remotely for analysis and alert determination.  

SlideMinders can be easily added to existing infrastructure and controlled using a variety of options to include the Sensemetrics data capture platform with the SMT Model, NavStar’s GeoExplorer or Call & Nicholas Instruments OREAD Server Software both of which work with the SMII Model.  Whichever option you choose, SlideMinders are designed to be reliable, budget-friendly, and easy-to-use. 

Our dedication to providing our clients with a superior and intuitive product at an affordable price has earned us a reputation as an essential component of any slope monitoring project. Call or email us today to discuss how a SlideMinder Slope Monitoring & Warning System can be integrated into your operation. 

We look forward to working with you!
