The DGT XL, introduced in 2003, is in full accordance with FIDE rules and regulations. It is the clock you will see most frequently in photo reports of top level tournaments, as it is the only clock that connects to the DGT electronic chess board, used for live internet broadcasting of chess games. It has all the advantages of the DGT 2010, the other DGT clock approved by the world chess federation and several extra options and features, which make the DGT XL the ultimate in chess clock technology.
Additional display information; timing system including period of play.
Option to mix the different timing systems to best suit your game.

Multi period Bronstein delay, used in US tournaments.
Up-count timing method, e.g. for Scrabble .
Clock's display shows move if the DGT e-board is used for online or PC play.

Positives:Many great features, fairly easy programmability, plugs into e-boards.Drawbacks:Doesn't program for plain delay, only does Bronstein delay.Final thought:This is great, but if you're looking for a DGT, go with the North American model. Otherwise, spring the extra money and get a Chronos.
