TM-SWIM was developed by ALGE-TIMING especially for aquatic sports. The demands for a device with an integrated USB-Interface was the main reason for the changeover from the SWC to the TM-SWIM. It combines the most powerful electronic with the rugged design of ALGE. The built-in amplifier and the built-in rechargeable battery make this device unique. The TM-SWIM is the most modern timing-device; the PC is connected by USB or RS232 is only the display and the keyboard of this device.
