I agree with what mtpockets said about cleaning the coil and scuff cover.
Otherwise no, I don't get a lot of falsing. It can sometimes happen when the sensitivity is set too high*, but I just lower it until the SE becomes stable. Sometimes I will let the SE re-noise cancel by pressing the button. Usually one or all of the above will eliminate all falsing.
Something else that is good to try is going to a smaller coil. Many times what we think is falsing is actually small targets on the edge of detection depth. A small coil will separate the good targets out of the mix.
I would try cleaning the coil and cover, get a good noise cancel, lowering sensitivity and see if anything improved. If not, then maybe someone else here might have some ideas.
*Sensitivity set too high may not mean much if you don't know where "too high" is. I have found that I can still get about the same depth at sensitivity 16 as I can at 28 in the mineralized ground we have here. So the setting is vague, but keep lowering it and the SE should settle down if it is running too hot on Sens.
I hope you find out what the culprit is.
