Propeller Calc vs ECPin Pro

This calculator can determine pitch, gear ratio, RPM, propeller slip and speed parameters. Enter any four variables, and it will calculate the fifth. Use the toggle switch to choose which field to calculate. Pitch is the theoretical forward movement for one complete turn of the propeller. Every inch of the boat in contact with the water induces drag. Therefore, the distance travelled differs since the propeller is "slipping" behind the theoretical distance it should travel with each rotation. The difference between theory and reality is called slip. Depending on your application, slip typically ranges between 5% and 20%. A lower number is only sometimes what you are after. Slip of a prop changes with operating conditions and is not a direct measure of efficiency. Please consult professionals for guidance. Happy powerboating

Time, temperature, and heat are all important factors when it comes to cooking. To master these factors requires a lot of time, experience and practice. We understand that not everyone has the time or expertise to get it right, even professionals cannot control these factors 100% of the time. In the past, traditional needle thermometers were used to determine the doneness by measuring the temperature inside the meat, but without real-time information. The result is often disappointing with rough and dry meats or overcooked food. ECPIN ET180 is designed for home cooks who appreciate the fine art of cooking and values precise cooking results. Simply insert ET180 into the meat of your choice, select the desired cooking method and doneness on the app, and let the oven and ET180 do the rest for you. You will be notified on your phone when it’s done. The wireless design allows you to cook it anyway and anywhere you want. Real-time data is transferred to your phone where you can monitor, analyze and understand the status of your masterpiece. The highly efficient power management technology allows you to fully charge the ET180 in 2 minutes with 4 hours of usage time. ET180 is water resistant and designed for easy maintenance. Just rinse it with soap and water to get rid of the cooking residue. The ECPIN app can monitor up to 8 ET180's at once, allowing you to cook multiple dishes or a large piece of meat that require different cooking status and data.
