I used to target monster black bass in a gin clear gravel pit 50 years ago using what best I can tell is that technique .
the biggest night crawlers I could ketch , just hooked thru the collar so they go bananas on just a hook and pitch it to them (visually located big bass) and watch them follow it as it sank to the bottom and then pick it up .
if this is similar to what you did it is in fact deadly as heck , those clear water big girls wouldn't touch anything else .
they would fall for that one EVERY time , didn't know this even had a name , interesting .
