The YSI Castaway is a unique solution that measures temperature conductivity and depth at a rate of 5Hz down to depths of 100m. Due to its fast response time the Castaway is designed to be lowered at a freefall rate of 1m/s.

Equipped with in-buit GPS the YSI Castaway takes a position at the start of the cast and also at the end.  Sound speed velocity and salinity is calculated internally without the need to interface with a PC. Results are shown on an in-built graphical display as soon as it has surfaced and got its GPS fix.

Should you wish to look at the data in more detail then the internal data can be downloaded onto a PC and read using our free CastAway software via the internal Bluetooth negating the need for any cables.

The system can also be deployed very quickly and only needs to be calibrated annually.
