Waydoo Subnado Underwater Scooter
◄ At a svelte 1.6 kilograms and just 38 centimetres long and six centimetres wide, this sub-aquatic plaything is distributor Movesea's lightest and most compact underwater scooter yet, with the ability to pull divers to the depths at speeds of up to 1.4 metres per second. The minimal design also means that in addition to the traditional dual handles, you can strap it to one forearm. The 100W, three-speed motor is good to go down to 60 metres, and the 98Wh battery lasts up to 56 minutes, and can be fully charged in 1.2 hours. £499, movesea.co.uk
