Bought a bench tuner, Peterson StroboPlus HD Strobe Tuner several weeks ago as several guitars were coming in for intonation and my hearing's not getting any better. I was reasonably impressed with it.
But strobe display time with the microphone was relatively short, and strobe rotation didn't settle as well as I hoped it would.
Tried a contact mic to see if there was any improvement (although advertising says it's mainly to help with background noise at venues)
The Peterson one is a bit expensive in UK, so for half that price I tried a Korg CM-200 "Improved Design" Contact Microphone (wider grip for headstocks)
It makes a big difference to the length of time the strobe display continues, also seeming to make the display significantly more stable.
AND I can still have the radio on while I'm working!!

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

I'm old enough to have purchased a Conn Strobotuner back in the day. It still works, and I still use it for serious fine tuning. I've had the same experience, and I employed the same solution. A clip-on contact mic is the way to go.
