Hi Hestbech,

Just to let you know I have a Mcgizmo UV with the 365nm Nichia, Titanium body. I have tried to find amber too and found it very difficult. So many other things light up on the sand like shells, seaweed etc that you cannot distinguish the amber from them. Daylight is better I am afraid.

A piece of amber I tested indoors does flouresce, it's just that in a beach environment you cannot distinguish it from everything else.
