This ODD No. 03 is a specially designed model built for precision training. Made from durable 401 steel, it features adjustable odor-release holes on top, allowing you to increase or reduce vapor output by sliding the mechanism left or right. It measures 7 cm high and 5 cm wide, and fits perfectly in the ACT! Scent Wheel and all other ACT training tools. This makes it an excellent choice for controlling odor strength during searches and fine-tuning your dog’s performance.

Using an ODD offers major advantages in detection training: it keeps odors contained, prevents contamination, ensures consistent vapor release, and allows you to present targets in a clean, standardized, and repeatable way. This gives your dog a clearer learning experience and makes your training more reliable and professional.
