CD V-700RP

The CDV-700RP is a Pancake probe especially designed as a replacement for the standard beta/gamma probe from your Victoreen or Lionel Model CDV-700 survey meter.  As a Pancake style probe, its broad Geiger-Mueller detector surface will substantially increase the sensitivity of your CDV-700 and enable detection of Alpha, as well as low energy Beta, Gamma, and X-radiation.
The Replacement Probe is configured with a 3 prong plug and lock-screw type connection.  To swap out your standard probe, simply unscrew it from its base and pull out the old Geiger-Mueller tube.  Then plug the 3 pronged Replacement Probe in its place, and hand tighten the built-in knurled lock screw.
The Replacement Probe handle incorporates a black vinyl grip that is adjustable for the perfect fit on your CDV-700 meter.  Complete specifications on the CDV-700RP Replacement Probe are listed in the table below.
