Possible audible laptimer ???
 

Just thumbing through the giant new Argos catalogue and I spotted this beauty:

Argos underwater timer

For £20 the technology is stunning but I'm not sure the earpieces could be worn with a bike helmet - might be worth a go though as its a radio as well !!!!


There is also this amazing piece of kit as well but it sadly looks to big for bike use...
