Scintrex respects K-9 teams and we love dogs! Dogs are remarkable because they can track and can detect through the air. But we are not in competition with them! When a dog team is not available, the N-2300 can always be available. The best possible combination is a K-9 team + a Scintrex N-2300. In fact, dog trainers use the N-2300 to help train. Fentanyls unfortunately take their toll on K-9’s and in the best practice modes, the N-2300 can be used to help protect officers, agents, handlers and dogs alike from fentanyl overdoses. Scintrex and K-9’s are partners, not competitors – and are in this job together.
