In order to combat PC and other plagues on my trees this year. I invested in a new sprayer. I had wanted a backpack battery powered unit but I wasn’t happy with the prices or buying a battery other then the same I am using for my other eq.
I ended up getting a Ironton ATV Spot Sprayer - 8-Gallon Capacity, 1 GPM, 12 Volt for $79 but its now down to $59.
Because it was so much cheaper $9 vs $100 I got a telescoping spray rod from Aliexpress
To improve my coverage I picked up some multi nozels
My power is coming from portable jump starter from harbor freight
630 Peak Amp Portable Jump Starter and Power Pack with 250 PSI Air Compressor (harborfreight.com)
The sound you here is because irontron ships a cheap pump, with a pressure switch rathe then a reflux type pump.
the plastic on brass fitting of course leaks leeks.
Fortunately able to fix that with some thread lock from harbor freight.
