DGT - North American
Multi-period delay settings are a breeze! Quick-set options permit instant set-up. Manual programming options are fast and intuitive and are automatically stored in memory. Suited for Chess, but it also times any two-person board games like Go, Shogi, Checkers, and Scrabble.
The DGT North American was developed in cooperation with the United States Chess Federation for the US market, but later also released on to the global market.
The Delay option was made to suit US custom and is different from FIDE clocks. It is a variation of the official FIDE Chess Clock.
