The Ernest Sports ESB1 gives you real numbers on every swing without the setup. Doppler radar measures your ball speed and club speed, and your smash factor, carry, total distance, launch angle and spin are calculated from those readings and the club you select, so every range session comes with feedback you can act on.
There is nothing else to carry or connect. Your numbers appear on the ESB1's built-in screen after every shot, so your phone can stay in the bag, and when you want more, the free ES Range app adds session history and training plans.
It is made for the player who values accuracy, ease of use and long battery life. Set it on the ground behind the ball, facing down the target line, and swing; a single charge covers a full week of range sessions, it packs into the included travel bag, and every ESB1 is backed by a 1-year manufacturer warranty.
