I have been "old school" for decades, using fluid and a tray. My fluid's about run out so I am considering purchasing a modern detector. Does anyone have experience with the Detectamark Spectrum detector? Any other recommendations? If it is important, I collect older GB and BNA, mostly 19th to early 20th century. Thank you.

I also use the Signoscope with acceptable results so agree. However still need fluid and tray for some difficult LC T1 T2 differentiation on QV line engraved.
