I've tested this against some known elements in my collection and the counter works well. The interface is intuitive and easy to navigate to change various settings and customize the display. I chose this as an economical option that would still allow me to have audible and visual queues. The ability to view the data (including as a graph) and export it is appreciated, as is having a quick tool for the standard conversions and equivalent metrics of Sieverts, Rads, CPM and dose etc. Would also note the battery came charged and has held up well for hours now. I look forward to taking this on my upcoming trips to the odd mineral shop or planned conventions. Don't look at other cheaper options on desertcart from xyz brands and vendors... This product has the quality you are really looking for. Review: Seems to be an excellent radiation detector. - I've worked in a facility that handles waste products that all have some level of radioactive contamination, so I am well familiar with Geiger counters. It appears to work well with a degree of accuracy. The manual is easy to understand and the functionality of the instrument and basic setup was straightforward. I like the fact that it has a built-in rechargeable battery, and a full charge will give several hours of operation. Hopefully, I will never absolutely need to use it, but in these times it was quite inexpensive and offers much mental comfort. ## Features - Real-time data logging every second into internal memory. - History data can be downloaded to computer - Rechargeable battery last longer - Free data Viewer PC software - Dosimeter mode, CPM count mode, Graph mode ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 1,247 Reviews | ## Images ![GMC-300S Digital Nuclear Radiation Detector Monitor Meter Geiger Counter Radiation Dosimeter - Image 1](https://m.media-amazon.com/images/I/615ZNdooHgL.jpg) ## Available Options This product comes in different **Material Type** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I got what I paid for and don't regret it. *by S***M on February 18, 2025* Exactly as described and well worth the price.
