Crowdfunding campaign launches for new head-up display for swimmers

This is one for pool swimmers, technophiles and those of you who like to be on the forefront of developments in swimming training devices. The team at Zwim, a start-up based in Palo Alto, California, have developed a heads-up display that tracks and calculates vital performance data in real-time while you swim. The device is integrated into a pair of swim goggle and monitors your heart rate, lap times, number of laps, calories burned and so on while giving you an instant read-out in high-resolution and full-colour. They are now seeking crowdfunding to take their prototype through to commercial production.

Backers at this stage are being asked to stump up $199 now for the device, including the goggles, for an estimated delivery of May 2018. The funding programme is scheduled to run for two months.

The device only works with the purpose built goggles but these can be replaced if they wear out. The company also has plans to provide Zwim with prescription goggles for glasses wearers.
