Geiger Models

In deciding which Geiger counter model to purchase, we recommend that you first decide between these two basic types of construction:

	Pocket Models, versus:
	Probe Models, that is, Models with External Probes

Pocket Models Probe Models
$195 to $525 $219 to $1,362

What is the difference between a Pocket or Handheld Model, versus a Probe model? The heart of a Geiger counter is its Geiger-Mueller tube or detector, and in a Pocket or Handheld Geiger counter, that detector is built right into the case. In a Geiger counter with an external probe, the detector is housed within the probe itself, attached by a cable to the base unit. See the pictures above:

Why choose a Pocket or Handheld model over a model with an External Probe?

The advantage of a Pocket or Handheld model is that it is generally easier to use, and more compact and lightweight. By definition, a Pocket model can be held in and operated by one hand, leaving the other hand free, without any distracting cables . Pocket or handheld models are also less expensive. For general area monitoring and in most instances where specific objects are checked for radioactivity, a Pocket or Handheld Geiger counter is usually sufficient.

Geiger counters with external probes offer these three advantages, which may or may not be necessary for your application:

	The detector can be easily maneuvered to "probe" in a tight area, such as in mineral prospecting, or;
	The external probe extends your arm length and can therefore be easily positioned to scan objects down low without having to bend over, or;
	The handle of the probe allows detection at a distance, reducing the chance of radioactive contamination on your hand.
