The second problem is faint nicks for caught behinds and faint touches off the glove leading to catches.
In both these cases, Hawk-Eye is useless and the Snickometer is inconclusive (as one can’t tell whether the sound has come from the bat or the pad at times).
So what happens if a DRS referral is made and the Third Umpire is still unsure?
Apart from serving no purpose, the team unfairly loses an appeal.
That’s where Hot Spot comes in. This piece of technology is near conclusive to solve the above mentioned cases and gives the Third Umpire something concrete to work with.
Hot Spot uses thermal technology to clearly show whether the ball has touched the bat, pad or any other part of the body.
In fact the issue was always to make technology conclusive rather than force DRS down everyone’s throat.
