Teaching 5 star - More?
For teaching how to use various calipers and the like this is an excellent tool so it does exactly what they state it will do and does so beautifully. BUT! If they could make it accurate it would be an amazing tool!!! The lines on the ruler, and vernier calipers would be extremely useful. Can you guys do this?? Everything else is perfect. Just need to calibrate. Is there a way to add a calibrate feature?
