The K9 and K10 anti-cheat alarms are two related products that operators often compare. Both are signal detection devices, but they differ in specifications and performance. The key question is whether either device actually stops EMP cheating — the answer depends on what you mean by “stop.”
K9 vs. K10: Specifications Comparison
The K9 is the older model, detecting signals in the 300-700 MHz range with a claimed detection distance of 3-5 meters. The K10 is the newer model, detecting signals in the 300-900 MHz range with a claimed detection distance of 5-8 meters. Both devices are detection-only — they sound an alarm when a signal is detected but do not block the signal. Neither device stops the cheating signal from reaching the machine board.
Do They Actually Stop EMP Cheating?
Neither the K9 nor the K10 stops EMP cheating. They detect it. When a cheater activates an EMP-style jammer near the machine, the K9 or K10 sounds an alarm. By the time staff hears the alarm and responds, the jammer has already triggered any false payouts it was going to trigger. The alarm informs you that cheating occurred. It does not prevent the loss.
Which Is Better?
The K10 is marginally better than the K9 due to its wider frequency coverage (300-900 MHz vs 300-700 MHz) and longer detection range. However, neither device provides the active blocking that is needed to actually prevent EMP cheating. For that, you need a device like the Gen2 that blocks the signal before it reaches the machine board.
If your fish table is showing signs of evaluating K9 vs K10 for EMP cheating protection, 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: Can I use a K9 or K10 in combination with a Gen2 device?
A: Yes. The K9/K10 can serve as a secondary alarm while the Gen2 provides the primary active blocking.
Q: Is the K10’s wider frequency range enough to protect against all EMP-style attacks?
A: No. Most EMP-style devices operate in the 300-2400 MHz range. The K10 covers only 300-900 MHz, missing the 900-2400 MHz range.
Q: How do I know if my K9 or K10 is actually detecting attacks?
A: The device’s alarm log shows detected events. However, without active blocking, there is no way to know whether the detected attack was successful.
Q: Should I replace my K9/K10 with a Gen2 device?
A: If you want to actually stop cheating rather than just detect it, yes. The Gen2 provides active blocking that the K-series alarms do not.
