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.

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.

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.

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.

Frequently Asked Questions

verified +347 experts reviewed it as the best choice in 2026
Q1 What types of radiation does FieldSentry detect?
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.
Q2 What is a safe level of EMF?
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.
Q3 Is it easy to use for beginners?
Absolutely. The clear LCD display and simple one-button controls make it easy for anyone to get accurate readings, no technical background needed.
Q4 How long does the battery last?
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.
Q5 Can it detect 5G radiation?
Yes. FieldSentry's RF detection mode covers 5G frequencies along with WiFi and cellular signals, keeping you informed about modern wireless exposure.
Q6 Is this better than a phone app for EMF detection?
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.
Q7 Is calibration required before I start using it?
No setup is needed. FieldSentry arrives pre-calibrated and ready to scan the moment you take it out of the box.
Q8 What's included in the box?
You'll receive the FieldSentry meter, a clear instruction manual, and a protective storage bag for easy transport and safekeeping.
