Extension fields can include a series of features, which can make shopping as novice confusion. The most important options in our tests include the measurement of the slope (elevation acquired or lost), a pinspotter (which zero in the pivot during monitoring), resistant to the weather, tournament mode, a trolley magnet and last but certainly not less important, stabilization of the image.
Other useful options of some of our favorites include an OLED display for a bright targeting overlap and Bluetooth connectivity to be combined with other golf devices such as a smartwatch for GPS data. More processing you get, the more features you will find, including options such as wind speed and direction, the compensation of the elements and more. Having said that, there are too many data and usually you will pay a premium as the functionality count increases.
