The Inspector EXP has the same valuable features as the Inspector Alert but, instead of the built-in detector, it offers the added versatility of an external probe. The carrying case has a clear window panel that provides a full view of the readout and count light, and access to the switches. Includes convenient hand straps and a belt loop for carrying the instrument and a small pocket for a check source. The probe can be attached to the carrying case for one-handed operation if desired. The protective probe cover folds easily out of the way during one-handed operation.
