That looks great. I use mine through a water fed pole and I am able to shoot around 35 feet away very accurately. If I used it more I would definitely get a battery operated unit like yours.
Just get a gas powered softwash system and never look back! I don’t use the battery sprayer unless it’s a real sensitive area that needs very little solution due to runoff issues
Same here, I have a system powered by a car battery that works great but I use the backpack system if I am in a small delicate situation.
