Scent Evidence K9 recently conducted a scent preservation kit case study to demonstrate the effectiveness of a preserved scent collected 4 and 1/2 years prior to the test. SEK9 CEO and Founder, Paul Coley, preserved his daughter Cassie’s scent with the SEK9 Scent Preservation Kit on 4/21/13. In this case study Paul and scent discriminate K9, Nancy Drew, trail the target in a busy Tallahassee library parking lot where multiple vehicles and people crossed the trail during the exercise. Nancy Drew was able to successfully trail the target. Preserve the scent of those you love and care for. Get Your Scent Preservation Kits Today!
