Software is simple but with all functions you are likely to need for survey and gamma spectrum work. Can download data to iOS device. ### 4/5 — Helpful for working near/at historic mine sites *2023-01-20* The app is a great addition to the already easy to use Obsidian detector. The mapping feature is especially helpful for my work restoring historic structures, many of which are on old mine sites. I have another device with a less sensitive GM tube that has picked up higher than background readings at some of these locations. With the Obsidian scintillation detection and mapping feature I can finally know which sites are hot and take the proper precautions. One thing I wish this app had was a glossary of sorts that described what some of the spectrum readings mean and how to read them. I am a definitely a novice when it comes to radiation detection and it would be great to have a built in guide that breaks down the readings and features in a way that a noobie with no prior radiation education can understand. Other than that great product! ### 4/5 — Almost Pefect *2022-10-04* I love being able to heatmap as I go throughout the day paired with the Obsidian Scintillator. My only issue is not being able to rename the logs after I start the recording. Other than that, no issue. ### 5/5 — Radex Obsidian *2021-06-05* It works as expected and can store the data. I can see all graphics and continuous measurements ## Frequently asked questions about RadexM ### What devices does RadexM connect to?
