An occasional look at products the travel industry insists we need.

WHAT: Aquapac's waterproof bags for cell phones and cameras.

AIMED AT: Beachgoers who worry about leaving their personal belongings unattended.

HOW MUCH: $24.99 for cell phone carrier, $29.99-$199.99 for camera cases.

BUT DO THEY WORK? Just when you thought it was safe to go into the water . . . someone starts eyeing the valuables on your beach towel. Aquapac comes to the rescue with its thick waterproof cases that let you swim with your cell phone and/or camera -- and use them in Waterworld as well. The bulky carriers, which hang (camera/cell phone) around your neck or clip (cell phone) to your swimsuit, are easy to open. Lockdown is another matter. When we submerged our camera, we failed to completely seal the top and a puddle formed. However, once securely closed, we could even snap pictures underwater through the clear window. As for our cell phone, talking through the padded case was like chatting through a dense bed of seaweed. But it's good to know that if we shouted "Shark!" we'd be heard.
