THIS is the moment a top Brit climber scoured a Tenerife ravine for signs of Jay Slater after his best friend said he "heard him slip".
Paul Arnott, 29, from Flitwick in Bedfordshire, was seen on the road line accessing places that even police officers haven't been able to over the past days.
Paul had cancelled a charity fundraiser so he could rush to the island and join the desperate search for the missing teen on Saturday.
Footage showed the climber looking for any signs of downward skidding tracks in the hopes of a clue on Jay's whereabouts.
The 29-year-old previously talked of his experience in harsh environments similar to the unforgiving Masca ravine.
He told the : "I know these environments, I know how harsh they are and how scary they are without experience."

"You have to be the best person you can be.
"I spend all my time in the mountains, I've assisted search and rescue in Scotland before, it's what I do."
Paul said he would stay until the teen was located, adding that he had joined the search every day since his arrival to Tenerife.
He said: "Drones and helicopters are good but they don't pick up everything.

"You're going to be looking at the most hazardous areas such as ravines and areas [where] there's potential for rock falls."
It comes after Jay Slater's best friend said he could hear the missing teen slipping on rocks during a final video call.
The 19-year-old phoned his pal Brad - who he was on holiday with in Tenerife - after getting lost last Monday morning.
Jay, Brad and friend Lucy Mae jetted to the island earlier this month to enjoy the three-day NRG festival.
After going to a rave that finished in the early hours of June 17, apprentice bricklayer Jay headed to Masca with two British men he had met that night.
He shared a final Snapchat from their Airbnb of a hand holding a cigarette at 7.30am.
Jay then tried to make his way back to his holiday accommodation - an 11-hour walk away.
But at around 8.50am he made a desperate call to his friend Lucy saying he was lost in the "middle of nowhere" and had just one per cent battery on his phone.
Jay also said he had cut his leg on a cactus and needed water.
It is unclear whether the call to Brad was separate to the one made to Lucy.
Now Jay's friend Brad has opened up their last conversation - saying Jay wasn't initially concerned about walking back to their accommodation.
He told Isla Traquair on ITV's This Morning he could hear Jay's feet slide on the rocks - signalling to him he'd gone off the road.
Brad said: "That's how I knew he went off the road because, you know when you walk on gravel, or whatever it is, you can... you know what I mean, stones."
He admitted, however, he wasn't worried at that point as Jay reassured him he was fine - but he did tell his friend to put his location on.
Brad added: "We were both, like, laughing about it. He said: 'look where I am'."

He said Jay then cut off as he had another call waiting - but promised to phone back.
Both Brad and his mum Rachel Hargreaves have vowed to stay in Tenerife for "as long as it takes" to support Jay's distraught family.
