Yes, anti-jammer devices for fish game machines are one of the most commonly deployed anti-cheat products in the arcade industry. A jammer — a device that broadcasts a signal on the same frequency as the fish table’s internal communication system — is the most frequently used cheating tool against fish tables. An anti-jammer device detects and blocks these signals before they reach the machine board.
How Anti-Jammer Devices Work
An anti-jammer device monitors the frequency bands that fish tables use for internal communication — primarily the 300-2400 MHz range. When it detects a signal in this range that does not match the expected profile of the machine’s own internal signals, it blocks the signal within 50 milliseconds. The blocking happens at the hardware level, using filters that physically prevent the signal from reaching the machine’s input circuitry.
The key difference between an anti-jammer and a simple jammer detector is active blocking. A detector sounds an alarm when it detects a jamming signal. An anti-jammer blocks the signal from reaching the board. The alarm is secondary — the blocking is what stops the cheating.
What Types of Jammers Are Blocked
Anti-jammer devices block all common jammer types used against fish tables. This includes broadband jammers that flood the frequency band with noise, targeted signal injectors that mimic the machine’s own payout commands, and pulse jammers that trigger single payout events at intervals. The device’s 300-2400 MHz coverage range covers the frequencies used by consumer-grade jammers available on online marketplaces and professional-grade units.
What to Look for in an Anti-Jammer Device
When choosing an anti-jammer device, look for three specifications. First, the frequency coverage range — it must cover at least 300-2400 MHz. Second, the response time — it must block signals in under 100 milliseconds. Third, the installation requirements — it should install externally with no machine modification. The Gen2 anti-jammer device meets all three specifications.
If your fish game machine is showing signs of jamming attacks or unexplained payout increases, send me a message with your machine model and a photo of your setup. I will do a quick remote check for free. Every device comes with a money-back guarantee, official invoice, express shipping, and 1-on-1 technical support.

Frequently Asked Questions
Q: How do I know if my fish table is being jammed?
A: If the machine pays out more frequently than its programmed rate, or if one player consistently wins at a rate above statistical probability, jamming is a likely cause.
Q: Can one anti-jammer device 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.
Q: Does the anti-jammer device interfere with the fish table’s normal wireless functions?
A: No. The device only blocks signals that match known cheating patterns. Normal wireless communication between the machine and its peripherals is unaffected.
Q: Can a cheater bypass the anti-jammer by using a different frequency?
A: The Gen2 device covers 300-2400 MHz, which includes all frequencies used by common jammers. If new jammers operate outside this range, the device can be updated.
