C.A.T Manager Online for iOS links your gC.A.T4 to the Radiodetection C.A.T Manager online secure cloud. Recording what users actually do with Cable Avoidance Tools is a vital component of a quality management approach to prevent damage and harm related to excavation of buried cables and pipes. To facilitate this, Radiodetectionβs gC.A.T4 records key parameters every second, and stores them in non-volatile memory. The data collected can be subsequently analysed using our PC application. For customers with a fleet of CATs the problem has been to manage and analyse the data from all these devices quickly, simply and accurately. This problem is solved with the release of the new C.A.T Manager Online service from Radiodetection. Use this iOS app to automatically transfer data from gC.A.T4s to the Radiodetection secure cloud. See data from all your CATs in near real-time, and ensure that all your operators are using their gC.A.Ts correctly. Use of the C.A.T Manager Online service requires agreement to a set of terms and conditions. Radiodetection makes no warranties of any kind, written or oral, statutory, express or implied, with respect to this app, including, any implied warranties or merchantability or fitness for a particular purpose other than as set out in the C.A.T Manager Online terms and conditions. This app is designed for use by businesses that have professional, trained, operators for their Radiodetection gC.A.T4 devices. Older gC.A.T4 devices may require a firmware update to function with this app. * iOS compatibility is only for gC.A.T4 produced from August 2016. Check the label above the battery compartment to verify if your locator is compatible

Aphex is the proven construction delivery platform. Site teams use it to plan the weeks ahead, run daily coordination and capture the record of what happened, all from one live plan. Think about everything it takes to run a site: the lookahead, staging plans, crew briefs, progress tracking and the daily diary. On most sites that's spread across spreadsheets, whiteboards and WhatsApp. The plan and what's actually happening drift apart, and the team absorbs the avoidable delay and cost. Aphex is one place to run the site. The mobile app puts it in your pocket.
