I found seven LCI laser levels in there hard plastic cases. There are seven of them, all in good shape, power up and work just fine. I don't have manuals for them and know little about them. They are for construction type work and are about 10 years old. model numbers 531 XV and 631 XV. I know these have far greater value than scrap! I have never sold on Ebay but that is where I think I'm going with these. Does anybody have suggestions or know anything about these instruments?
