The new models as stated by the website are 2000D, 3000K and 4000K where 2000D is the basic two camera system with 50 golf courses included. For professional players, there are 3000K and 4000K, where 3000K included 2 super cameras and one video camera and comes with 50 golf courses while the top end model 4000K comes with and addition video camera and 20 additional golf courses over 3000K model.
