The CATS-Diary (CD) is the universal name for our highly customizable sensor board. It can be customized to suit your exact requirements and  thereby reducing the size and weight to a minimum. It can be equipped with the sensors of your choice, whether pressure and GPS, or speed and compass or all together, just let us know and we will try to match your requirements in the smallest design possible. In addition, the new CATS-Visualizer tool (in development) makes analysis much easier by letting you recreate all recorded sensor values graphically. Like all our devices, they can be populated with solar cells for longer deployments. The CD usaully requires a customized float and attachment, which CATS is specialized to do just that.
