Man I've got a lot of question for you, so you're fishing from the bank. How deep of water do you think you can cast into? And why are you choosing to use a spoon? It will be darn near impossible to not get caught up a lot, those things sink like rocks and are called 'jigging spoons' for a reason. Not meant to be cast from shore unless you're just going to burn it back above the bottom, which defeats the purpose in the first place.
If we know how deep, and what type of fish you're after, someone can probably provide some good suggestions.
