When trolling for big game Billfish it's a must to have teasers with scent in your trolling spread. We use scent teaser and also strip teasers on most trolling lines. The billfish have a keen sense of smell and detect scent from miles away. Using Scent Blazer scented teaser help draw the billfish to the back of the boat. We found that a pink teaser we use is alot like a squid to a billfish.
