Calibrating a Back Pack Sprayer", which reminded me of this short video series from Rittenhouse evaluating various features from a number of popular models, enjoy!
I am not a fan of Solo backpacks. They are difficult to repair. Even a skilled technician requires 2 hours to rebuild one. Keys to selecting a backpack:- professional grade- quality wand- external pump(easy to rebuild)- repair parts readily availble.These criteria exculde most home store backpacks. I prefer Shindaiwa or Birchmeier.
