Marine product designer on Dragons’ Den

This coming Monday evening

The man behind the Waterbuoy goes on BBC2’s Dragon’s Den next Monday.

The device has a built-in balloon which goes off if you drop it in water. It can support up to 1kg, the designers say, making it ideal as a key ring or portable GPS attachment.

James Halliburton, the man behind Waterbuoy, will go before the Dragons’ Den panel of Theo Paphitis, Peter Jones and Duncan Banatyne on Monday 19 November at 9pm.
