Definition A lightweight hand-held conductivity, temperature and pressure (depth) (CTD) sensor designed for quick and accurate profiles in shallow water settings. Each cast is automatically referenced with both time and location using a built-in GPS receiver. SonTek CastAway software displays profiles of the casts in addition to mapping the locations of the data collection points. Data integrate directly with RiverSurveyor-Live, HydroSurveyor and HYPACK software, and can be exported to MATLAB for applying sound speed corrections. The CastAway features a rugged, non-corrosive housing with colour LCD screen, AA battery power for 40 hours of continuous use and computer free operation. The instrument has a 5 Hz response time and sampling rate. Data can be downloaded by Bluetooth wireless. Depth range of the instrument is 0 to 100 m, in water temperatures of -5 to 45 degC. Conductivity can be measured in the range 0 to 100,000 microsiemens/cm, with a resolution of 1 microsiemens/cm and an accuracy of +/- 0.25% or +/- 5 microsiemens/cm. Temperature can be measured in the range -5 to 45 degC, with a resolution of 0.01 degC and an accuracy of +/- 0.05 degC. Pressure can be measured in the range 0 to 100 dBar, with a resolution of 0.01 dBar and an accuracy of +/- 0.25% FS. GPS is accurate to within 10 metres.
