Review on πŸ“ Highly Efficient Slide Rule by John Swain

Revainrating 5 out of 5

Good tool for the truck. $20 value for the whole day!

Good companion for HVAC professionals. Contains a lot of useful information in a small package. Very well presented. Also has many electrical formulas. Good refrigerant troubleshooting information for new technicians. I like to have this with me when checking airflow to check size. Also comes with a barcode scan for a free app download. Thanks for that.
