I have a Chapin one gallon. Had it for years. Don't use it much. Plastic wand. Adjustable plastic nozzle. Adequate from my point of view. I think there is an intake filter on the pickup tube at the bottom of the tank. Fits easily behind the seat of my truck.
No battery--no power.

 

I just checked--I also have a Chapin 1.5 quart hand sprayer. I used to use it for nutsedge (Sedgehammer), and sometimes for T-zone.
Plastic.
Again fitted behind the seat of my truck or in a tiny cubbyhole behind the spray tank. Not sure--there might be a screen or filter in the wand handle.
The in-tank pickup tube has a little screen at the bottom. But this tube can be easily unscrewed and cleaned in case of clogging.

 

Of course, for small (and cheap) spot-spray jobs, something like this worked well for me. I had several.
I cut off a larger plastic bottle and made a sort of holster for it and attached it (zip ties) to my spreader as a way of carrying it when spreading dry fert. Just grab the hand-held when a spot of oxalis or violets appeared.

What's your budget? B&G is hard to beat.

 

We just picked up a Lesco and it leaks.

 

There are some inexpensive battery options available. RedMax, Scott’s and others are selling the same sprayer just rebranded. The Scott’s unit is on Amazon for about $90.

 

Thank you all. I want a pump, not a battery.
You look at the reviews and it's hard to find a clear winner.

Perimeter treatments and Spot weeds. Not had any problems the past several years except one I left in the shed, the heat caused the main body to crack and leak. I have 4 in service at the moment working fine.

 

Thank you Burnie!
I actually was giving that 2-gallon Chapin 26021XP serious thought.

 

I bought Dewalt's $47 2-gallon sprayer because the design and quality appears to be a rung above the rest in the 2-gallon size.

B&G stainless steel is the one to get. Primeline Sprayer

I own both a 1 & 2 gallon. Brass wand, brass nozzle with adjustable head for different spray patterns.

 

The round up brand 2gal one on Amazon is decent..

OP did ask for an 'exceptional' sprayer. Pony up!

Then yes by all means I agree it’ll run you what about $300 for a single one gallon. Yes it’ll be great. Go for it let us know how your investment went.

 

Throwing my 2 cents in. For a 1-2 gallon pump sprayer, I like the Husqvarna one at Lowes.

From my understanding, this model as well as several other brand pump sprayers are manufactured by The Fountainhead Group - Even Lesco ones and their warranty is pretty good.

Personally, I like a stainless steel wand, which come standard with the Lesco ones, or you can purchase it after. As for tips go, I would look at TeeJet ones.

Lastly, I have not had luck with Chapin sprayers, but that is just me.
