In the Model 133 series, those Model numbers with the “-1” on the
end are the waterproof versions of this detector. The waterproof
detectors have the same characteristics as the non-waterproof
models, other than they are waterproof, contain an O-ring, and do
not have a “C” connector on the probe end (base). A 30-meter (100-
foot) cable is hard-wired into the waterproof detector. The
waterproof models also weigh slightly more and have a slightly larger
diameter than the others.
Model 133-4
Note:
The detector does not contain any consumable materials.
Note:
If the detector is used in a manner not intended by the
manufacturer, the detector may not function properly.
