The Gadget Show (Channel 5, 7pm)

IN pursuit of Tomorrow's World, The Gadget Show seemed to have seen the future when it came to reporting on new technology and its impact on our lives.

From 2004 the ultra-competitive Jason Bradbury and Suzi Perry built a steady audience alongside the posh and controlled tones of Jon Bentley and an ever-changing list of other presenters. The show moved from 30-minutes of flying sparks to an hour and the masterstroke of adding the chaotic influence of Ortis Deley earned the franchise the right to run roadshows and grab a flurry of Guinness Book of Records entries.

In 2012, that all changed. Bradbury, Perry – who has moved successfully to Formula one presenting if you don't compare her current features to Gadget Show days – and Deley were dropped so that Bradbury and blonde bombshell Pollyanna Woodward could tour the world testing the latest inventions. My remote, and I suspect quite a few others, zapped elsewhere.

After Bentley's return in 2013, last year the show brought back Deley (replacing Woodward) and gave Olympic skeleton gold medallist Amy Williams a try in the "Suzi Perry" slot.

Series 22 sees the quartet aiming to get fans more involved than ever and encouraging viewers to submit their own tech dilemmas to the team, asking for help and getting their questions answered by experts.

As usual, the team are also going on the road, exploring the gadget globe from California to Germany and interviewing the tech stars of the 21st Century – YouTube and Vine personalities, gamers and more.

The presenters also pair off to compete against the pros, who this series will include Olympic swimmers, international photographers and even private detectives.

Tonight, the team goes behind the scenes with Brighton-based Dan Middleton from the family-friendly YouTube gaming channel The Diamond Mindcart, which is based around Minecraft. An internationally known geek star, reviewer and gaming expert, DanTDM's videos were watched by more than 400 million times in July and he has even become the inspiration behind a toy range.

Meanwhile, Bradbury and Deley join forces to take on a master detective at her own game. They want technology to give them the edge to figure out which of three suspected criminals committed a car crime.

Ortis also travels to California to check out a new bionic eye implant designed to help blind people regain their sight.

Williams gets to grips with a 3D-printed arm and a fully articulated robotic hand, as well as meeting the people who use them. Bentley dons a smart watch to find out if we should be rushing out to buy one.

Finally, in Gadget Help, audience member Dan asks the team for a new tool to help him lose his L-plates and finally pass his driving test.

Police Interceptors (Channel 5, 8pm)

I think I'm making history by highlighting two Channel 5 shows on the same day, but this is the second in a ten-part look at the police who operate in the North-East. In Durham and Cleveland, dog handler Jimmy Grieves (the other one), catches a thief in the act and a squad raids a drugs farm. Meanwhile, Darren Cawthorne has to deal with a particularly irate motorist. Over at Durham Tees Valley Airport, a team is called in to assist with an emergency landing.

All Change at Longleat (BBC1, 9pm)

The second episode of the three-part documentary chronicling changes to the Wiltshire stately home sees Ceawlin making an unusual find in the attic. As he searches through memorabilia his grandfather collected, he comes across a rare watercolour painted by Adolf Hitler, while in the safari park, a new animal house is being built for an ageing elephant. Meanwhile, Emma finds herself missing her friends and family from her old life in London and is keen to find a role for herself on the estate.
