A criminal-accomplice whose job is to watch out for incoming policemen while his friends commit a crime (usually drug dealing, burglaries, safeguarding supply houses, etc). Spotters are basically human alarm systems that criminals use to warn them when the cops come near. They usually stand on a corner to get a better vantage point and to give their friends plenty of time to run away, flush the drugs, etc. The warning is usually a shouted code, but can sometimes also be visual; modern criminals now use cell phones. Often times, spotters are juveniles who can't be effectively punished by law for aiding in a felony.

A small blowtorch with a bent knife attached in such a way that the end of the knife is in-front of the flame, and will heat up when the blowtorch is turned on. It's a portable tool used for the weed smoking technique known as spotting in New Zealand, where marijuana is rolled into small balls (or spots) and pressed between 2 hot knives, while the user positions their mouth above and inhales all the smoke. Most people will use a gas stove to heat the knives, but more experienced users may make a portable spotter using a blowtorch.
