ZWING is a great way to get your downrigger setup to the correct depth while minimizing and controlling the set-back angle behind the boat. Whether you’re fishing for Salmon, Walleye, Pike or other freshwater slow trolling targets, or slow trolling an offshore live bait ZWING is the way to go. ZWING is also the perfect companion setup for adding TrollPro-DR for underwater recording using your GoPro camera. ZWING 350 operates in a wide variety of trolling speeds and is available separately or in our great ZWING/TrollPro-DR Combo.
