Many users make these errors with dew controllers:
- Setting heater power too low: Dew still forms, ruining your view.
- Setting heater power too high: Can cause thermal currents that blur images or damage optics.
- Poor heater placement: Uneven heating leaves spots vulnerable to dew.
- Ignoring sensor calibration: Faulty readings lead to inefficient heating.
- Underestimating power needs: Drained batteries cause heaters to shut off mid-session.
- Skipping pre-session tests: Surprises like non-working heaters can spoil your night.
Tip: Combine dew controllers with dew shields and proper storage for best protection.
