EMP jammers — the most common cheating tool used against fish tables — work by broadcasting an RF signal that overrides the machine’s internal communication. Understanding exactly how this signal affects the machine helps operators understand why blocking is the only effective countermeasure.
The Step-by-Step Mechanics of an EMP Jammer Attack
Step 1: The cheater acquires a signal generator that broadcasts in the 300-2400 MHz range. These are sold openly on online marketplaces for $50-200, labeled as “RF testers” or “signal generators.” Step 2: The cheater activates the device while sitting at or near the fish table. The device begins broadcasting continuously or in short pulses.
Step 3: The RF signal travels through the air and is picked up by the fish table’s internal wiring harness. The wiring acts as an antenna, conducting the signal into the machine’s main board. Step 4: The main board receives the signal on its input channels. Because the signal is on the same frequency as the machine’s legitimate peripheral communications, the board processes it as a valid command.
Step 5: Depending on the jammer’s configuration, the board may trigger a coin credit, a payout event, or a bonus activation. The machine records the event as legitimate. Step 6: The cheater collects the payout or plays using the free credits, then leaves. The operator sees the revenue loss in the next reconciliation.
The Exact Device That Blocks EMP Jammers
The Gen2 anti-cheat device blocks this attack at Step 3 — before the injected signal reaches the main board. The Gen2 monitors the frequency bands used by the fish table and compares every incoming signal against the expected profile of the machine’s own internal communications. When it detects a signal that does not match — such as an EMP jammer’s broadcast — it blocks the signal within 50 milliseconds using a combination of passive filtering and active cancellation.

Frequently Asked Questions
Q: How close does the cheater need to be for the jammer to work?
A: Consumer-grade jammers typically work within 1-3 meters. Higher-power devices can operate from 5-10 meters. The Gen2 device blocks signals regardless of the jammer’s power level within its coverage range.
Q: Can the jammer be disguised as another device?
A: Yes. Jammers are commonly disguised as phone chargers, power banks, car key fobs, or even inside modified smartphones. The device’s appearance does not affect its signal.
Q: How do I know if a specific player is using a jammer?
A: If a player consistently triggers payouts or bonus events at irregular intervals without demonstrating matching gameplay activity, they are likely using a jammer.
Q: Can one Gen2 device block multiple jammer types?
A: Yes. The Gen2 covers the entire 300-2400 MHz range, which includes the frequencies used by all common consumer and professional-grade jammers.
