What... No Ultrasonic?

So today I let myself down a little. My a.m. pt had a pacemaker and I wasn't able to use the ultrasonic. I thought that I would do fine without it because he didn't have too hard of calculus. Little did I know how much I rely on my ultrasonic because when it came for a scale check, I had missed spots galore! I really am taking this learning experience to heart because I want so badly to be a good clinician and I want to be good at my hand instrumenting. Goal: for the next few pts (after mockboard) I am not going to use my ultrasonic. I want to make sure my skills are up to par and that I'm not just falling back on the ultrasonic. Wish me luck!
