The spots where you might spot some spotters are gyms. In gyms, spotters assist others during weightlifting or workout exercises to ensure safety and proper form, making them the natural places to find spotters actively helping lifters.

Additionally, in a different context like games or military simulations, spotters can be found in strategic locations such as behind rocks or hills with a clear line of sight on an area (e.g., "Death Valley" in the game Arma 3).

For aviation enthusiasts, "spotters" often refers to planespotters who watch and photograph aircraft, and they gather at optimal spots like airports and viewing areas known for good visibility of air traffic.

In summary:

• Fitness spotters are found in gyms.
• Military or game spotters are found in elevated or concealed tactical locations.
• Aviation spotters gather at airports or designated planespotting locations.
