For the last 10 years, I have been using the Halco sorcerer for trolling and have caught a variety of fishing including GTs and a 32-pound barramundi on it. Grouper love this lure and are usually the first to hook up. The swimming action is great when trolled slowly from a boat and it swims deep - so be careful of bottom rocks. I found the hooks rather weak and I have changed them to stronger ones. It is very effective in estuaries and river mouths. The silver colour works best for me. A timeless lure that I always carry when out trolling!
