Compliant with FIDE, IGF, and Chinese Chess Association rules: 42 preset modes (e.g., 120min/40moves +30s, 60min-30s/step countdown) eliminate setup errors. The seesaw buttons switch players in ≤0.1s—perfect for blitz chess.
Coaches set multi-segment timing (e.g., 90min + 30min/20moves +10s/step) to simulate complex tournaments. The move count display tracks players’ speed, and parameter saving reuses custom modes for repeated training.
• Seesaw Buttons: Tilted side indicates active player; quick response for fast chess.
• Dual Screens: 1.8-inch LCDs with 5-level brightness (readable in sunlight: ≥300 nits).
• Back Rule Printing: 42 preset rules printed on the back—no manual needed during tournaments.
• Shell: ABS + PC composite (withstands 1.5m drops onto concrete).
• Screens: Anti-glare panels (readable under direct sunlight).
• Circuit: Industrial-grade chips (stable at -10°C–50°C for outdoor tournaments).
