SR = Slow Rolling MR = Medium Rolling Based on the scan and details from a real Smelt, this hard lure has a super realistic profile and look in the water. The lure swims with an enticing and provoking roll and will dart out to the side when twitched. The horizontal balance and slow rise in the water, provokes the fish to attack the lure hard. Great multi species lure for both trolling and casting. Great for pike, Zander, perch, trout and bass! • 3D details • Great darting action on twitch • Super rolling action • Horizontal Balance • Slow rising on spin stop • 3 super sharp SGY 1X BN trebles #4 • SR runs 0,5-1,2m • MR runs 1,5-3m
