I always assumed wired devices were the safe ones. FieldSentry showed me otherwise, catching a spike near my desk lamp that genuinely shocked me. I moved my router and lamp cords and finally stopped getting that afternoon headache at my desk.

Built to Find What's Actually Spiking

Three-Axis Peak Detection

Three perpendicular sensors catch the strongest part of every field, so tilting or rotating never hides a spike.

Readings You Can Act On

Built on the same triple-axis sensing building biologists trust for home readings, within 10-20% of professional tools.

Instant Warning System

Color-coded alerts trigger the moment magnetic fields pass 1 mG, so you know the instant a reading needs attention.

No Setup, No Guesswork

A crisp LCD display and simple controls make expert-level detection easy. No training required.

Based On Real and Honest Experiences

I bought FieldSentry mostly out of curiosity, not expecting much. It picked up dangerously high readings near our old wiring, and after we fixed it, my migraines went away within two weeks. Every homeowner I know is getting one now.

I used FieldSentry to check my baby's nursery before we moved her crib in. The clear display showed me exactly which corner to avoid, and the color-coded alerts made the whole process foolproof.

Frequently Asked Questions

+164 expertsreviewed it

FieldSentry detects magnetic fields, electric fields, and RF radiation, including WiFi, cell signals, and 5G frequencies, so you get a complete picture of your environment's exposure.

Most experts recommend keeping sleeping areas under 1 mG for magnetic fields and under 10 µW/m² for RF. FieldSentry's color-coded alerts are set against these benchmarks, so a green reading means you're in a safe range.

Absolutely. The clear LCD display and simple one-button controls make it easy for anyone to get accurate readings, no technical background needed.

You'll get 20 to 25 hours of continuous use per charge, and the automatic shutdown feature helps you save battery when you're not scanning.

Yes. FieldSentry's RF detection mode covers 5G frequencies along with WiFi and cellular signals, keeping you informed about modern wireless exposure.

Phone apps rely on your phone's antenna, which isn't built or calibrated to measure magnetic or electric fields at all. FieldSentry uses three dedicated sensors, so you get real triple-axis readings instead of a rough RF-only estimate.

No setup is needed. FieldSentry arrives pre-calibrated and ready to scan the moment you take it out of the box.

You'll receive the FieldSentry meter, a clear instruction manual, and a protective storage bag for easy transport and safekeeping.
