How about laser tag?

Sure, but some vests used for scoring transmit wireless signals.   The laser tag gun and the circuit that detects hits pose only a low risk of interference. However, some vests contain magnets and radio frequency transmitters to communicate with the scoreboard. Both can cause problems, so be sure to maintain a 6-inch distance between the magnet or transmitter antenna and your ICD. The last thing you want to do playing laser tag is get hurt.
