Whether it's for weeding and feeding, or controlling pests - users are equipped for the Job. It's GUARANTEED TOUGH.

Review: Good quality, and not too heavy. - Reading reviews before I purchased this, I was a little concerned because people said it was heavy. I have used both Solo and Echo hand pump backpack sprayers over the years as a Private Applicator. Honestly, I can’t say it was much heavier than either of those. I started by putting it on the back of my golf cart and driving around. It is top heavy and would fall forward if I hit a bump. Next I tried walking with it and it was comfortable and worked well. I used a DeWalt 8AH battery. I sprayed a total of 21 gallons of herbicide (5 batches and a clean-up) and there were still 2 of the 3 green lights on indicating it had only used 1/3 of the battery. I’m impressed with it and think I made a great purchase.
Review: fantastic sprayer. - This thing is AWESOME !!!!!! I can't tell you how much I love this sprayer. I have been spraying Permethrin around the house to kill off the bugs. This works great with little effort. When you fill it to 4 gallons it gets a bit heavy (think of it as a workout with a backpack :). It does have waist straps so that helps out a lot. With 4 gallons, I'm able to go around my whole house and spray to kill of the bugs. Works great. I would definitely buy it again in a heartbeat especially since many of my powertools are from DeWalt and use the same battery packs. Side note. When you get it, you might need to prime it. Getting a garden hose and blasting water into the vent (as suggested) worked REALLY well. After that, it works every time without priming it.

## Features

- Heavy-duty nylon-reinforced hose effectively avoids kinking
