I used a Jeppesen CR3 in the early 80's along with a Casio digital watch, sharp pencil, sextant, and math to navigate jet aircraft as a navigation student......YES we used to use sextants in airplanes at mach .9 to figure out ..... not where we were....... but where we had been 5 to 10 minutes prior....... because that was the state of the art in navigation over the ocean where no land based navigation aids could be placed. Today your phone will tell you where you are NOW and navigational skills are lost on all but a few. Not to mention, we put men on the moon with slide rules and less "computer" power on the entire mission than in a smart watch. **Q: So what is this? A circular slide rule or something only for flyers?** A: It serves as both a slide rule and instrument for flyers **Q: Could Posting to Hong Kong ?** A: Hi, I think you would like to know if I can send this item to Hong Kong. The answer is yes but shipping would cost more. Thank you. Everywhere ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars but arguably better than E6B *by A***R on Reviewed in the United States on April 5, 2017* For those of you deciding between the CR3, CR6, or E6B.E6BCons: Kinda obnoxious with wind computations, cardboard or aluminum materialPros: You probably already have oneCR3Cons: Winds are different and a little more complicated, but arguably better than E6B. It also can't be improvised as a plotterPros: Much better feel with build quality versus the CR6, and spinning is as smooth as butter. Provides every function plus more than the E6B. Few things you can do on the wind side (cos & sin) like find descent rate with GS and angle, find precise wind components, VOR point to point navigation, wind correction angle etc, and the front side includes TAT window, mach number, cursor for precision etc. Jeppesen.com/cr for instructions.CR6Cons: Made of flimsier plastic that CR3, inner wheel has the same radius as the outer wheel, so it can be hard to use if holding the edges, develops very small warp from flimsier materialPros: Newest version of the CR design, updated larger font, yellow color for high contrast / easy to read in dark conditions, additional recovery coefficients and mach window has more precisionI personally find the CR3 to be the best. I will admit the black on grey isn't the best color, but you will get used to it. I see some other gentleman was having issues with precision versus his E6B. I can testify that the one they sent me is just as precise as all my other wheels. I'm led to believe that he just didn't set it correctly. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great classic. Does a lot. *by R***T on Reviewed in the United States on March 26, 2023* Got used to this computer back in the day when I worked as a charter pilot and instructor. Glad to see Jep still makes them. As always this is a well built, smoothe and accurate tool. "No batteries required" and gives "good enough" results. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars still an important pilot tool *by D***C on Reviewed in the United States on March 15, 2023* Everyone flying today is using electionic flight gear but the old ways are still important. If you can master a circular computer then you truly understand the fundamentals of flight planning and best thing, no batteries. this is right up to Jeppesen standards and I like like the colors. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/3470407-jeppesen-cr-3-circular-computer-6-diameter-js514237](https://www.desertcart.pt/products/3470407-jeppesen-cr-3-circular-computer-6-diameter-js514237) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-06*
