Foil competitions are judged with electrical recording apparatus.

Only the indications of the recording apparatus can be taken into consideration for judging the materiality of hits. Under no circumstances can the Referee declare a competitor to be hit unless the hit has been properly registered by the apparatus (except as provided for in Articles t.49, o.17, o.24, or when a penalty hit has been awarded).

When using the apparatus it should be noted that:

1. If a non-valid hit has been scored the apparatus will not register a possible valid hit scored on the same side of the apparatus.

2. The apparatus does not indicate there is any priority in time between two or more hits which it registers simultaneously
