It's a reference device, for checking something is on frequency or resonant (about a zillion uses really)
Found a circuit diagram & component list here:-

A guy sold me one of these last weekend at a yard sale. I'm too new and inexperienced to know anything about it, but it looks like new. The model is lG-5280. Can someone tell me exactly what it's purpose is? It looks interesting, but I know nothing about it. I did open it up and it looks neatly assembled, and requires two batteries for power. I'd appreciate any information.
