1 Use the X-beam wrench for loosening tight and rusty old bolts without hurting your hand. The ends are at ninety degrees to each other, so you always grip a wide, flat surface, not a narrow edge.

2 What do you do if your car battery goes flat in a storm, and you don’t have jump leads or roadside assistance? The Black & Decker Simple Start allows you to start your car without getting wet. It plugs into the 12-volt socket in your car, and it’s designed to restart your car in ten minutes.

3 This is designed to jump, dive, roll and move over and under water at 30 mph using a 175-hp engine. Innespace Sea Breacher is a two-seat, 5-metre long, underwater vehicle, shaped like a dolphin. It acts as a jetski and as a fast submarine.

4 Have you forgotten where you put your keys? Use this smart device to find them. Simply attach the electronic tag to your keys. Then, if you can’t find them later, switch on Loc8tor, and it will point in the right direction – not only left or right, but up or down too. It will show you where your keys are. At the same time, the tag on your keys will emit a beeping sound.

Thisdigital-sonaralarmsystemtransmitsasignaltoyourboatcrewifyoufalloverboardintothewater.Itconsistsofthreedevices:thealarmpod,thehydrophoneandthedisplay.The alarm pod is an egg-shaped device, worn by each crew member, which transmits a digital-sonar coded signal when it is submerged in water.

The hydrophone is a transducer, attached to the inside of the boat hull, that listens for signals from the alarm pod.

The display is a control unit, attached to the dashboard of the boat, which shows information from the hydrophone by means of LEDs and digital displays.

When the MOB (man overboard) hits the water, the alarm pod is submerged. The alarm pod has two pins. If these pins are in contact with water for one second, and the contact is constant across the two pins, the pod is activated. It then sends a signal under the water. This signal is picked up by the hydrophone, which relays it to the display.

Four things then happen immediately:• Bright LEDs in the display show a visible alarm.• Speakers on the boat sound an audible alarm. • The MOB’s location is shown on the display via the internal

GPS system.• Red and green LEDs navigate the boat to the MOB’s location.
