On one occasion he removed the head entirely and replaced it with a small, round mirror, which spun rapidly when he tapped its edge with his finger and hypnotised anyone who looked at it.

The Eighth Doctor had resumed using this model by the end of his life during the Last Great Time War. It was the second and final model the Doctor used thus far that bore an emitter-ring head.

It featured regularly in season 16 during the Key to Time saga. The Doctor's Time Lady companion Romana constructed a sonic screwdriver of her own similar to the Doctor's. It is depicted as being smaller and sleeker than the Doctor's, and he was sufficiently impressed with her design that he attempted to swap screwdrivers with her in The Horns of Nimon (1979–80). By season 18, both script editor Christopher H Bidmead and producer John Nathan-Turner were eager to downplay the device as much as possible. Romana II constructed her own sonic screwdriver, which was so impressive that the Doctor attempted to substitute his own with hers, but she noticed the switch. ( TV: The Horns of Nimon) Her version also included a silencer. ( AUDIO: Luna Romana) She later gave it to the Doctor. ( PROSE: Lungbarrow) Nonetheless, during the final term of her presidency, her third incarnation used a sonic screwdriver. ( AUDIO: Intervention Earth) This is perhaps the most noticeable difference between the hero prop and The Sonic Screwdriver URC. The Sonic Screwdriver URC has to come apart so that the batteries can be changed. To avoid unsightly parting lines and fixing screws showing on the outside of the Sonic Screwdriver, the ideal place for this was in the middle, and the cover ring was used to hide the join. This provides an elegant solution but means that the cover ring has to taper less than this feature on the original prop.

During his imprisonment by INC on Ha'olam, the Eighth Doctor's sonic screwdriver was confiscated. After his escape, he briefly used a replacement screwdriver resembling a slender metal rod with a crystal at its tip.

This model could glow with an "almost white" light and emit great heat, be used to sharpen surgical instruments and be turned "on" and "off". ( PROSE: Osskah) Quadrigger Stoyn possessed a sonic screwdriver in his workcase aboard the Doctor's TARDIS, which he had been working on shortly before the First Doctor stole the ship. ( AUDIO: The Beginning) This new model had a very mechanical and complicated-looking, TARDIS blue, metal handle with multiple emitters, once again resembling the inner structure of the time rotor itself. The emitter was once again blue in colour, and the ring of emitters could all light up in a circling motion when activated. ( TV: Hell Bent) He continued to use his sonic sunglasses as well, thus giving him two choices of sonic instruments. ( TV: The Husbands of River Song, Extremis)

The Eleventh Doctor immediately showed off how much bigger his was, to which the Tenth Doctor claimed that his future incarnation was compensating, remarking that " regeneration, it's a lottery." ( TV: The Day of the Doctor) Each model used the same software. Essentially, the sonic screwdriver in use by the War Doctor was the same as that in the Eleventh Doctor's possession, some 400 years later. ( TV: The Day of the Doctor)
