Last updated March 9th, 2025:

Kits were briefly out of stock for the past couple weeks due to a shortage of Geiger Counter tubes. Geiger Counter kits are in stock again and ready to ship in all configurations. Geiger Counter kits are also available from Amazon.com.

For fastest shipping of Geiger Counter kits, please order a boxed kit from Amazon (link). I’m also happy to ship other configurations here (it just takes a few extra days).

HV Rescue Shield kits are in stock. Bare PCBs are in stock. Rescue Shield kits are also on sale at Amazon.

I’m now selling SBM-20 Geiger Tubes on Amazon. They come in a nice protective plastic case with end caps that is guaranteed not to roll off the table. There is also a brief datasheet inside. These really nice tubes are becoming difficult to find and available in a limited quantity.

I typically ship orders within 5 business days, unless otherwise stated here. If you need kits fast, please consider ordering from one of my distributors.
