You should receive a list of recommended equipment and instructions on how to order them with your matriculation packet. Most people will buy the equipment as a complete package from the school.
I'd recommend checking with the school for a definite list, but this is what I recall ordering (as part of the complete equipment package), all Welch Allyn brand:
1) Pan Optic Diagnostic Set, Special (product no: 97810-MS)
2) BP Family Practice Kit (product no: DS58-MC)
3) Harvey DLX 2HD Stethoscope (product no: 5079-325S)
4) Tuning Fork C-512
5) Hammer Buck (Reflex Hammer)
6) Measuring Tape
Total Kit Price: $760.00
Get a medical equipment bag to hold everything because you will sometimes be called on to bring all your equipment with you. Also, even though I purchased the recommended stethoscope, I don't like using it. Instead, I often use a Littmann Master Cardiology stethoscope, which I purchased in addition.
