IS IndoSurgicals Tuning Fork (Set of 128, 256 & 512)

Excellent packing, delivery on time.The quality of forks is really good and c9mes in a good and sturdy case.As an ENT surgeon I would suggest this product as a must buy for all the residents and clinicians.Value for money.Forks have good vibration and resonance.Prongs are symmetrical.Over all a good value for money product.

It came on time. And the instrument was of good quality.

Good product

The best part is the frequency of the forks seems to be correct , this is verified using well known resonating tube experiment, f= V/(2*(L1-L2)) where L1 and L2 are resonating lengths of tubes.Alignment is the problem with these forks if your are keeping them on same plane ,which is acceptable and doesn't matter much. Have used these forks for carrying various audio experiments . Price should have been little lower. To conclude, these tuning forks are best buys and serve the purpose.

The tone produced by the 256 Hz tuning fork is actually 230 Hz. So if anyone is looking for any pure tone related activities, this is not very accurate, but otherwise for clinical examination the tone doesn't need to be accurate, and hence this will do the job.Build, quality, duration of tone produced is adequate.Edit: So I actually bought two, of which one was as I mentioned above, but when I used the second one that was spot on 256 Hz, and sustained the vibrations longer. So the first one was just poorly made. Better quality control is needed then.

PROS-Well built and finished nicely.Tiny form factor so it’s east to carryCONS-Sound Decays rather quickly.Performing clinical tests properly becomes challenging.

Cost effective.

Good value for money. Useful both for musical instrument tuning and ear testing.
