Detector models:

The two most common models are the SCR-625 C, and the SCR-625 H. The chief difference being the older model C had the control box with meter mounted on the arm, while the later model H had a separate control box that attached to a belt. The amplifier bag on the model C was slung over the shoulder, and it used a M-356 speaker as an audio indicator. The model H amplifier bag was a back mounted bag and used a HS-30 headset. Headsets and speakers are interchangeable. Below are pictures of the minimum necessary for a operational mine detector. In addition to the items in the pictures, be sure there is the wooden chest and an amplifier bag.

A working SCR-625 mine detector makes an excellent demonstration of WWII electronics technology that is a popular hands-on demo with older children, and would not be considered a weapon for school display.
If properly repaired and adjusted, you should be able to detect a lightweight but large diameter metallic object at greater than one foot (30 cm). For demonstrations, I have found just 3 layers of heavy duty aluminum foil, 10 x 10 inches square (25 cm x 25 cm), is easily detected. It will not detect small objects like coins. All of them I have tried have a minimum amount of hum, especially at higher sensitivity or when using the headset. Originally they may have worked a little better, but age has taken its toll, and there have been no vacuum tubes of the type used by the detector made in over 50 years.
Any detector lying around for the greater part of 50 years will not work without repair and adjustment, but the technology is well within the expertise of any technician with experience in tube type radio or TV repair. I offer free advice and support for anyone wanting to repair theirs. See attachment at the bottom of the page for a video of one I fixed (with sound).
The SCR-625 requires a 103 volt battery and two “D” cells. Making a homemade 103 volt battery made out of a series of 9 volt batteries is well within the skills of someone with some basic woodworking handyman tools and some soldering experience. The biggest expense in getting a mine detector working is batteries, and you will need batteries before you have any idea whether the detector will work or not.
