No problem. I had seen these in many of Dave's videos but want sure what they actually were.
Google image search can be your friend here. Rather than searching through heaps of websites that are probably going to be the wrong thing, I now google "double banana plug" for example, go to image search and look through for the type I want. It helps to give you a whole lot of styles that you can then start to narrow down.
I started doing it a while back, I was looking for a particular style of gopro mount but had no idea what it would be called. I tried searching for a few hours through various web pages, then thought about image search. About 5 minutes later it was located, ordered and on it's way.
