MOESAPU Geiger Counter Nuclear Radiation Detector Nuclear Water Seafood Detection Radiation Dosimeter with LCD Display, Portable Handheld Beta β Gamma γ X-ray Rechargeable Radiation Monitor Meter

For low level measurement, seems sensitive. My radiation implant knocked it off scale and it alarmed nicely

Easy to use. Seems accurate. Price is really good for the quality

I have dropped this many times onto concrete and it has not broken yet! It is pretty accurate, however only measures beta, gamma, and x-ray. It also includes a dosimeter function. It is quite easy to use, and includes in-depth instructions in the user manual. Overall, a good product for the price!

A good Geiger counter at a good price. The on-line reviews are accurate.

Our cat was irradiated for thyroid disease.I bought this device to check the litter box and other items around the house as her radiation levels diminished.It's easy to use and provides plenty of information and modes for detecting radiation levels.Well worth the investment.

Compared well with an engineer's pricier model.He literally didn't believe the price when I told him how much I paid for it.Actually thought I must be lying.

So many detectors in this price range have lousy sensitivity. This one has the J321 GM tube which for a cheap detector is an excellent tube. It easily shows increased activity on Uranium glass and easily detected the increased activity from Thorium infused welding rods.There are better radiation detectors out there but not at this price point. Not only that but there are many more expensive units that do not perform as well as this one.

Does include the J321 geiger tube. Haven't tested much but I was happy that it does include the good tube.
