HOT Spot inventor Warren Brennan claims that protective coating on the edge of cricket bats diminishes the ability of the technology to pick up nicks from batsmen.

Brennan wants this coating removed from the edges of bats so Hot Spot can have the greatest chance of working properly.
"During the current Ashes series, the DRS (decision review system) has been highly controversial, with Hot Spot in the eye of the storm", Brennan said.
"Our technology has been criticized for fine edges that have gone undetected. More than anyone else, BBG Sports wanted to know why.

"Following the Manchester Test match earlier this week, BBG Sports analysed contentious Hot Spot decisions from the Ashes series and decided to purchase several of the latest generation of cricket bats to undertake thorough testing.
"BBG Sports observed that the majority of bats had some form of protective coating that would wrap around onto the edges of the bat. Strangely enough, this protective coating would cover only half of the edge of the bat and not the entire edge of the bat.

"BBG Sports believed this could cause the front-edge of the bat to have a different thermal signature than the back-¬edge of the bat."
Testing over the past three days has, in the opinion of BBG Sports, provided conclusive findings.
"The type and thickness of the protective coating unquestionably affects the thermal signature of the Hot Spot system," Brennan said.
The International Cricket Council was advised earlier this week on these initial findings and has committed to further testing over the coming weeks.
"BBG Sports believes that in order to achieve optimum Hot Spot results then the removal of protective coating from bat edges needs to occur.
"This will allow for the best thermal signatures between cricket balls and natural timber cricket bats."
Umpires appeared to lose confidence in Hot Spot during this series, giving or upholding in some cases contentious decisions even though there was no evidence from the technology that the player had hit the ball.
There was no suggestion that any player was using the coating to deliberately try and beat Hot Spot.
Almost all players use coatings to protect modern soft pressed bats that can easily break up.
