Nottingham: The company behind Hot Spot will undertake tests to see whether the cameras can be tricked by the use of artificial substances on the edge of the bat. There is a belief among players that Vaseline can reduce the chances of a thin nick showing up, although it has only ever been rumoured that such tactics are used.
Concerns about the effectiveness of Hot Spot came to the fore when VVS Laxman survived a caught-behind appeal on the second day at Trent Bridge. England were convinced there was an edge but Laxman was equally convinced he hadn't hit it. The third umpire said there was a noise but it wasn't clear from where. Michael Vaughan, the former England captain, sparked controversy by tweeting the suggestion of Vaseline and Stuart Broad was later asked and admitted checking the edge of Laxman's bat but finding nothing.
Warren Brennan, the owner of Hot Spot, has previously said the device's accuracy is around 90-95% and can be impacted by such things as bright sunshine and the speed of the bat in the shot. He now says that it is possible that a substance like Vaseline could reduce the technology's effectiveness and tests will be conducted to try to find conclusive results.
