YCS 71 Ultra Trinocular Microscope
The YCS 71 Ultra is the precision-focused trinocular stereo microscope of Mr. Yang's YCS line: a 0.67x-4.5x zoom with an 11-step fine-tuning knob delivers 6.75x-45x total magnification through high-eyepoint 10x/23 wide-angle eyepieces. Its integrated dust-resistant objective needs no external dust cover, each eyepiece adjusts independently (-5 to +5 diopter), and rotatable rubber eyepiece guards set the working distance. Available as Package B (microscope only) or Package C with the YCS X80 industrial camera and CTV 0.5 adapter for live monitor work.

Frequently Asked Questions
Who makes the YCS 71 Ultra - is it a genuine YCS product?
YCS (Repair Master) is the tool brand built around Mr. Yang, one of the best-known repair educators in the phone repair community. Vexagoo is an authorized distributor of QianLi and YCS repair tools, so every 71 Ultra is factory-genuine with full warranty support.
What is the difference between Package B and Package C?
Package B is the complete microscope: two 10x/23 high-eyepoint eyepieces, main unit, bracket, column, and base. Package C adds the YCS X80 industrial camera and the CTV 0.5 adapter on the trinocular port, so you can drive an HDMI monitor, record repair video, or run a training screen out of the box.
How does the YCS 71 Ultra compare to the YCS 7050X?
Both cover the mid-range window (6.75x-45x vs 7x-50x), but the 71 Ultra is the precision pick: an 11-step detented zoom returns to exact magnifications repeatedly, and the integrated dust-resistant objective removes the need for an external dust cover. The 7050X is the continuous-zoom value pick. See the full 71 Ultra vs 7050X comparison.
How is the YCS 71 Ultra different from the QianLi 6558 Gorilla?
The Gorilla is the high-magnification flagship with a 3.5X-90X continuous zoom for fine BGA ball inspection. The 71 Ultra covers 6.75x-45x with an 11-step fine-tuning knob and a dust-proof integrated objective - precision and low maintenance over raw range. See the full 71 Ultra vs Gorilla comparison.
What does the integrated dust-resistant objective mean in practice?
The objective housing is sealed with a built-in high-transmittance lens, so dust and flux smoke cannot settle on the front element. You never fit, remove, or clean an external dust cover - the lens stays protected at the physical source.
Can I wear glasses at the eyepieces?
Yes. The 10x/23 eyepieces are high-eyepoint wide-angle, each side adjusts independently from -5 to +5 diopter, and the rotatable rubber eyepiece guards let you set a comfortable working distance whether or not you wear glasses.

Yes. Vexagoo is an authorized distributor of QianLi and YCS repair tools, offering factory-direct wholesale pricing on both Package B and Package C with no strict minimum order quantity. Contact us on WhatsApp or email for bulk quotes and distributor pricing.
