    We are currently using the lesco spray gun but going into next year we are going to convert all sprayers to a TeeJet AA30L-22425 GunJet spray gun. This will have the 18" extension connected.... My question is which spray tip would you recommend or have experience using?

    Thanks

    That is a great gun when configured so that the shut off is at the tip. I use a 23L 7676-18 myself. That is really good for preventing drip of bare ground or noinselectives on unintended areas. Think what would happen if Round Up dripped on a lawn from a normal spray trigger and wand. A 11004 tip will lay down 1 gallon per 1000 at 40 PSI and a moderate walking pace.

    Equipment choice is really a very personal thing. My treasure might be your trash.

    I am not a fan of the Tee Jet 30 gun because of where the hose attaches. That gun doesn't feel right in my hand. If I swing my hand I have to also swing the hose.

    Instead I buy Pressure wash guns that the hose attaches in the Handle. I leave on the fast snap for the Nozzle and I will even use the smallest Pressure wash tips. A 15 Degree fan can be very useful when spot spraying. Or pop in a wider angle fan for blanket spraying. Adding a quick snap longer wand is an other advantage. Adapters for standard Tee Jet nozzles like the 8003 can quick snap into the gun or extensions also.

    Let me add that I do some aquatic certified and spray aquatic weeds from a boat. Weeds grow in the shallow water where a boat can't always get near. My 12V 2 GPM pump and a # 3.5 15 degree wash pressure nozzle does a nice job of reaching out and touching someone. Plus at 40 PSI, it doesn't mist or drift because the droplet size is large enough. I will even quick snap in a Zero Degree nozzle to really reach out. a 80 Degree Tee Jet nozzle can't get close.

    I agree but the only problem is that the only wands that I know of that have the shutoff at the tip are straight. For spot spraying you need a curved wand and I have had success using the strainers that have a check valve built in- really a spring loaded ball that will shut off when the pressure drops to about 5 psi to minimize dripping.

    Great point that I missed in my post, and the point of Tee Jet 30 is the shut off feature. Yes I use those check valve strainers every where I can. I install them right where the Quick snap couplers screws into the Gun. That way every tip I snap in has a check valve.

    However on my aquatic sprayer I don't use a Strainer Check Valve. They cut down on the Volume or GPM. You need a lot of carrier when applying aquatic Herbicide.

    BTW I like a curved wand for spraying most things from Spot, Blanket and even shrubs. Large shrubs need to be sprayed on the inside as well. A curved wand lets you spray in all directions just by rotating it once it is inside the canopy.

    Structure PC is different and the standard can sprayer is the $ 300 one gallon SS B&G with a shut off at the end of the wand not unlike the Tee Jet 30. While it is a great piece of equipment, the one gallon size and cost is not what I would want to use for L&O work.

    I like the setup Ric. How well does that gun stand up to herbicides? I've considered using one of those for R-up jobs but was unsure just how long they would last.

    The $ 19.95 model from Northern Tool last a couple years. They general start dripping at about two years. But they are so cheap I just throw them away when they go bad. Roundup is no big deal for these guns.

    I use these guns for both total kill and selective herbicides. Fact is my Aquatic Gun stays wet with Herbicide 24/7/365 because all I do is turn off the Pump and drain the pressure. I only use the aquatic set up once a month.

    Pressure wash nozzles start at size 3 and come in half sizes. I keep sizes 3 to 4.5. These are rated for like 3000 PSI so at 40 PSI they spray a much lower volume. I change nozzle sizes to match which ever 12V pump I am using. (They all are different) I want the pump to come on when I trigger the gun and shut off quickly when I un-trigger the gun. I don't want my pump to keep turning on and off when I am spraying. Nor do I want the pump to fall behind my spraying. From my experience the smaller Tee Jet nozzles either 8000 or 11000 series will cause the pump to turn on & off continually.

    For those that asked i will be spraying pre emergent, dye & post. This will be the first year that i have converted to these teejet guns with the extension due to us adding the dye to our applications.

    Im switching guns so that when i apply the dye that it will look more uniform and not splotchy.... what tip do you guys prefer to cover the best area?

    I think the idea is to apply the herbicide evenly not the dye.
