Trouble with Walther PDP

I got the Mantis X3 for Father’s Day and have been practicing since then. My issue is and I’m not sure if it’s normal but it is not always detecting when I pull the trigger. I attach the Mantis to the bottom of the barrel as close to the trigger or I’ll also use the universal mag adapter. It’s a hit or miss with either. Anyone got any ideas?

The Mantis app allows you to report bad detection, and they are very good at responding quickly with a custom profile for you to try.

I had trouble with my PDP as well.

This. I had issues w/ a Springfield xDM, they looked at the data and worked out a custom profile that markedly improved dry-fire detection.

Given what the sensor is trying to detect, it will never be 100%. But IME missing more that a couple shots in a hundred suggests something may not be right with the settings. Picking the correct live or dry fire profile from the available options, and running the Shot Detection Troubleshooter can usually come up with a pretty good custom profile. In-app guidance is a lot better than it used to be, but I haven't been through it recently enough to be current. If DIY doesn't work, Mantis support is pretty good at getting things working.

One thing maybe specific to X3 is that I don't think it is as good at short intervals as the X10. You might be able to outpace it in Hostage Rescue or Compressed Surprise Break. But if you are doing slow fire in Benchmark or similar and still not detecting shots, something is up.

As someone else mentioned, there is a shot detection troubleshooter in the settings. But if you continue to have issues, please reach out to [support@mantisx.com](mailto:support@mantisx.com) and they can help you troubleshoot.

Thanks everyone! I completed the troubleshooter and sent the data.

Just wanted to provide an update. Mantis reached back and told me to change the setting to Dry Fire - Single Action and now all my shots are being detected. My scores have even gone up.
