I think callipers can make a big difference then!I'm not using half-unit marked syringes because I could not find them with longer needles (1/2").
They are digital and read up to 0.01mm. I'm not sure about a screw or if they can be locked, I think so. Thank you for the link, I will read and start using them.Here's the sticky on Dosing with calipers. Did you get the ones with the screw above the display so the arms can be locked and ones that read up to 0.01mm (and not just 0.1mm)?
