I had previously tuner simpler but imprecise (and mostly not very adaptable to different instruments).
This tuner is suitable for all instruments (wind, string ,...) and even voice, he has a jack for electric instruments. It can afford to choose a time (perfect for early music in particular) and supports all frequencies (from the lowest to the highest). It is therefore an indispensable tool for musicians playing multiple instruments. Its small backlit display is very handy in dark rooms. And its option to issue a given note can also be very useful for singers and choral conductors.
While tuning in more expensive, but also in the most efficient. Very good value for money.
If I were to invest in this new tool, I'll do it without asking any questions.
