In sports, movies and in life in general, people usually find themselves rooting for the underdog. When it comes to shopping though, They often have a harder time going with the lesser known brand. Of course, as professionals, we are required to look past brands and really focus on features and overall performance. Regardless of the brand name on the box. If it is tough for us who do these types of things for a living, we get that it’s really tough for a typical consumer to look past the brand name.

In this particular occasion, we were tasked with putting the Field King Max 190348 Backpack Sprayer to the test! Field King has been around for a while now. Actually putting out very decent products to build an excellent overall track record. Even so, they are typically still viewed as a brand a little bit in the shadow of other more prominent brands.

In this case, we will try to shed some more light on this product. To begin with, the Field King Max 190348 Backpack Sprayer has a 4-gallon tank which is almost a standard size for most backpack sprayers across the board.

The Field King Max 190348 Backpack Sprayer comes with 4 adjustable nozzles for different spraying possibilities. The nozzles are interchangeable, some people like this feature better than having one nozzle with 4 different modules. What we can say is a definite plus for this product is the nozzles it comes with look like they are of higher quality in comparison to the ones offered by other brands. Most manufacturers typically use plastic nozzles all across the board.

Field King claims that this sprayer can spray with a power of up to 150 psi. This pressure is very rarely reached by any of the other competitors even with their more expensive top of the line products. This Field King Max 190348 backpack sprayer also comes standard with a pressure regulator that can go from 25 to 150 psi. Allowing the operator to use this particular product for a wide variety of products.

What are people saying?

The Field King Max 190348 backpack sprayer has overwhelmingly positive reviews everywhere. It is clear this backpack sprayer is a favorite among professionals and weekend gardeners alike.

The issues that have been reported by other users have more to do with the distribution of the product than the actual product itself. There were a few reports indicating sellers shipped them a used product. We even read someone's review that said the sprayer was sent to him used with chemicals still in the tank! I'm not sure what was going on there, but subsequent reviews don't mention anything about this, and we didn't experience it so it must have been resolved.

What we liked

The Field King Max 190348 is a great backpack sprayer, period. A few things that really stand out are the build quality and comfort.

The attention to detail and the high-quality parts used really set The Field King Max 190348 apart from the competition.

The nozzles are built to last, and the 4 different options included will handle just about any job. All 4 nozzles worked great and felt a lot more durable than cheap plastic ones from other brands. The problem with them though is that if you want to switch in the middle of a job you have to turn it all the way off and change them out. Something to carry the 4 nozzles in could be of help. Over time they tend to get lost while working since you have to keep them in your own pockets or something like that.

The stainless steel wand is durable and doesn't wobble around like some other brands.

No leaks or complaints in general with the tank. As long as everything is tightened correctly, you should have no problem with leaks.

The comfortable harness features a full coverage back pad, waist belt which is extra wide for support and a chest strap to keep shoulder straps tight and supportive. The comfortable grip on the wand and lockable trigger help prevent hand fatigue and generally makes the job more enjoyable. The Field King Max 190348 is surprisingly comfortable.

What we didn't like

We didn't find anything that really stood out as a problem with the Field King Max 190348. Unless you have a large enough job to consider a gas or battery powered option this might be the only sprayer you need!

While researching the Field King Max 190348, we noticed a couple of people complaining about leaks. We haven't experienced any leaks with our sprayer but often times leaks can come from poor maintenance.

Maybe a little too much pumping is required, especially when you need it to go up to 150 psi. This is to be expected though, this is a manual pump sprayer after all.


I give it 4.5 stars!

The Field King Max 190348 is a definite buy in our book. This is one of our favorites as a manual pump backpack sprayer. The excellent spray coverage, large capacity, and comfortable straps mean you'll finish your work in a fraction of the time. The impressive build quality and durability mean this could be the last backpack sprayer you'll have to buy. Why waste money on disposable chemical sprayers when you can just keep refilling your Field King Max 190348?
