Nikon has announced the signing of Ian Poulter as ambassador for its Coolshot and Coolshot AS Laser Rangefinders.

The world number ten golfer and his caddie Terry Mundy are to use the distance measuring devices when making tournament preparations until 2015, and Mundy will carry the brand's logo on his headwear. Poulter said 'Nikon's laser rangefinders are the best around and you won't get a more accurate reading with any other laser'.
