YCS 71 Ultra Trinocular Microscope vs QianLi 6558 Gorilla Microscope
Two trinocular stereo zoom microscopes for repair benches: QianLi's high-magnification flagship and the YCS 71 Ultra, the precision pick of Mr. Yang's line with an 11-step fine-tuning zoom and an integrated dust-resistant objective. Both carry a third camera port and share the same post-mount stand standard.
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.

Which One Should You Choose?
Choose the QianLi 6558 Gorilla if your work regularly lives at 45X-90X for fine BGA ball inspection - its 3.5X-90X range is the flagship standard. Choose the YCS 71 Ultra if you value repeatable 11-step magnification, a dust-proof objective that never needs an external cover, and the Package C option with an X80 camera and CTV 0.5 adapter included. Both mount on the Pushi repair desk.
YCS 71 Ultra Trinocular Microscope vs QianLi 6558 Gorilla Microscope — FAQ
Which reaches higher magnification?
The Gorilla: 3.5X-90X versus the 71 Ultra's 6.75X-45X. For inspecting BGA solder balls at the highest powers, the Gorilla has the headroom. The 71 Ultra covers everything up to 45X, where most daily board-level work happens.
What does the 71 Ultra do that the Gorilla does not?
The 71 Ultra's 11-step detented zoom returns to exact, repeatable magnifications - ideal for consistent photo documentation - and its integrated dust-resistant objective removes the need for an external dust cover. Package C also bundles an X80 camera and CTV 0.5 adapter.
Can both mount on the same stands?
Yes. Both use the post-mount standard of the QianLi/YCS microscope ecosystem - the Pushi repair desk, the YCS Dragon multi-axis arm, or standard pillar stands - and both accept cameras on the trinocular port.
