Illumivein® Premium Vein Finder

How it reveals veins invisible to the naked eye: 

This new and improved model lets you work even faster. Even more accurately. This tool emits a ~700 nanometer  frequency red light  that is naturally absorbed by veins. This creates a dark shadow wherever a vein exists.
