A brilliant buy for our holiday this month has been the Vivitar Vivicam 5399 underwater digital camera, organised by Middleagedad (who is officially 'in charge' of gadgets like this).
It's a normal digital camera capeable of taking very good quality hi resolution pics such as the one of middleteenageson in the pool above.The little camera is encased in a waterproof box that allows you to go up to 15 metres underwater and snap away. We're used to those rubbish throw away underwater affairs which are generally crap, but this is darn clever.
Being digital it uses a standard memory stick (which slips into the side of my laptop) and is powered by 2 AAA batteries. Even teenagesons, budding amatuer photographers themselves and quick to dismiss any flighty gadget as' pants,' recognise this is a good deal.
Middleagedad bought it on Amazon a couple of weeks ago for a very reasonable £40, but since then it seems to have gone out of stock. You can also get it on gadgetsquick which is also currently out of stock (I'm sorry I know that's not helpful) but strongly suggest you keep looking out for it pre your summer hols, as it's a good buy.
