Yes, EMP blocker devices for fish game tables exist and are one of the most commonly requested anti-cheat products in the arcade industry. The term “EMP blocker” is widely used by operators to describe any device that blocks the electromagnetic signals that cheaters use to manipulate fish tables. While true EMP (electromagnetic pulse) weapons are rare in arcade cheating, the devices that operators call “EMPs” are actually RF signal generators that operate in specific frequency bands.
What an EMP Blocker Actually Does
An EMP blocker — more accurately called a signal injection blocker — monitors the frequency bands that fish tables use for internal communication. When it detects a signal in these bands that does not match the expected profile of the machine’s own signals, it blocks the signal before it reaches the machine board. The blocking happens at the hardware level, within 50 milliseconds of detection.
The device does not need to know what type of signal is being used. It filters all signals in the protected frequency range that do not match the machine’s normal communication pattern. This means it blocks both simple jammers that broadcast noise and sophisticated injectors that spoof specific data packets.
Does the Device Block Actual EMP Attacks?
True electromagnetic pulse attacks — the kind that can damage electronics — are extremely rare in arcade cheating. The devices that operators commonly call “EMPs” are low-power RF signal generators that operate within the 300-2400 MHz range. The Gen2 anti-cheat device blocks these signals effectively. If a true high-power EMP weapon were used against a fish table, it would likely damage the machine’s electronics, and no consumer-grade anti-cheat device could prevent that.
Choosing an EMP Blocker
When choosing an EMP blocker, look for: frequency coverage of at least 300-2400 MHz, response time under 100 milliseconds, external installation with no machine modification, and a coverage range appropriate for your venue layout. The Gen2 device meets all these specifications.

Frequently Asked Questions
Q: How do I know if my fish table is being attacked with an EMP-style device?
A: If the machine pays out more frequently than its programmed rate, or if players win at rates that exceed statistical probability, an RF-based cheating device is likely being used.
Q: Can an EMP-type device damage my fish table permanently?
A: Consumer-grade cheating devices operate at power levels that do not physically damage the machine. However, repeated exposure to strong signals can stress the input circuitry over time.
Q: Does the EMP blocker require any calibration for different fish table models?
A: No. The device is pre-configured to cover the frequency bands used by all common fish table models.
Q: Can one EMP blocker protect multiple fish tables?
A: The Gen2 device covers a 2.5-3 meter radius. Fish tables within that radius can share one device. Machines farther apart need individual devices.
