Do you have any tips for making sure students can see the right bits under the visualiser. I struggle to get everything shown, or out of focus. Do you use templates, or something else?

I’m not sure. I use an Ipevo and sometimes stand it on its box or similar to give it more height. I bring things into the picture as and when they’re relevant and the students by this point have this equipment in front of them. I often use a pencil or something to pint at things.
