Surdex has released a new, more powerful version of its web-based image inspection tool, SurCheckSM 4.0 (formerly known as CPAT). This new version is the result of over 5 years of continuous improvement and has met with outstanding reviews.

SurCheck makes it extremely quick and easy for customers to review and approve imagery. Artifacts and other potential issues are identified prior to delivery, leading to quicker remedial action and final delivery.

SurCheck has been completely re-developed in HTML5/Javascript for cross-browser compatibility and can be easily learned by a clients’ staff in less than an hour.

Release 4.0 offers more flexibility and enhancements over the previous version of the tool:Initial_Screen500x350
