HUNT mode allows you to vary the speed of your kicker in set sequences. This has two distinct advantages: You are able to run patterns which speed up and slow down the movement of your bait creating more realistic presentations. Second, you are able to search through rpm ranges to find the speed the fish are reacting to and lock it in. HUNT mode is an unlockable feature pre-programmed into all iTrolls which means if you decide to upgrade at a later time, you can do so by contacting iTroll directly.
