If you want to be 19 feet deep let the bandit out 50 feet then clip on a 2oz weight and go an additional 10 feet for a total of 60 feet out. You can do different leads and you have to add the two diving depths together example if you let out the bandit 30 feet it will be 9 feet down then add the 2 oz weight and let it out an additional 18 feet which puts the weight at 10 feet down for a total of 19 feet down. You just need the dive curves for the bandit and the 2 oz weight and add them together. The precision trolling app does this for you with a 50 foot lead. Speed will effect this as well these numbers are at 1.5mph, faster will be slightly shallower. Always keep your baits above the fish they always feed up. If the water is very clean and clear the fish will probably be shallower than you are marking them because your boat will push them down when you go over them.
