The M300 was specifically designed and optimised for watersports. Whether it's kitesurfing, windsurfing, or sailing, it will give you the readings you require to monitor your session. It gives a precise measurment of current, maximum and average speed via GPS, heading accurate to 2 degrees, distance measured, lap history etc. There is no more guessing on who was the fastest, but just an accurate reading, and it will also help you understand how to acheive  better performance. The M300 is water resistant and like all other models, has interchangable covers.

All Sport Tool 300 series are very compact (79x78x27 mm) and light,  just 120grams, and come complete with a practical arm band. You won't even notice you are carrying it around. There is a Sport Tool for everyone... each model is optimised for a particular sport giving you the readings you require. Contact us if you need to purchase a different model for other sports. The complete lineup consists of: A300 R300 S300 W300 X300.
