Who writes these guides?
The Shinyzen trade team, using the specifications of the models we build. Where a guide states a figure, that figure comes from the product data on this site.
Can you advise on which model suits my market?
Yes. Tell us the retail price band, the climate and the use case, and we will point at the models that fit and explain the trade offs.
Do you publish a catalogue I can share internally?
Yes. The Download Centre carries a PDF catalogue and range spec sheets generated from the same data as this website.
Do the guides cover models you do not build?
No. Every model named in a guide is in our catalogue, so you can move straight from the explanation to the product page and the specification.
How do I turn a guide into a quotation?
Decide the magnification, objective size, prism grade and coating, then send those four things with your quantity. That is enough for us to quote on FOB Chongqing terms.
Ask Us the Question the Guide Did Not Answer
Our trade team answers specification questions directly on WhatsApp or by email.
