The PRINZTRONIC CHESS TRAVELLER is a compact but powerful full-feature chess computer. A single set of batteries will power it for about 10 hours -- enough for all but the very longest trips -- then it warns you when the batteries are low. You can choose from 8 levels of skill and reset them in mid-game. A unique multi-move key steps you quickly through the book opening of your choice. Setting up and verifying board positions are a ball, using on of the quickest and neatest systems in the industry, in combination with the attractive integrated chessboard.
The computer has eight levels of play varying from 3 seconds per move to up to 3 hours per move.
