Competitive swimmers train continually to improve their stokes and lap times. And now there is a product that can help them improve while swimming without having to stop to get the current stats. Introducing the Marlin, a small swim meter that attaches to your swim goggles providing real time stats that you can hear through the built in bone conduction headset.
This nifty little device works great while swimming in a pool as it provides lap times and stroke counts. It's also great while swimming in open water due to the built in GPS which not only tracks your distance and speed but also helps to keep you on track. The audio feedback is perfect to give you all of the pertinent information without you having to look up out of the water or stop swimming all together.
The unit cost will be $150 and can be purchased from Platysens website where they are currently offering a preorder discount. There is also a version available online that does not include the open water option.
