PRO48 Solenoid Activator/Chatterbox

Irrigation problems are often problems with the electrical portion of the sprinkler system. Sprinkler systems work on the idea that 110 volt AC is converted to 24 volt dc and sent down the wires leading to a solenoid attached to a valve at the appropriate time. If any of these electrical components fail, the system fails. The Pro48 tests all of the critical electrical components and does so in an easy to follow LED system that walks a user through the process component by component.This system of checks tests out the clock or controller first, then the wires, and finally the solenoid, which are all of the electric components of a sprinkler system. So with a Pro48 tester, a user quickly determines which of these 3 parts is at fault.

The Pro48 Multi-Function Irrigation System Tester is a value-priced tester for irrigation contractors and maintenance personnel. This is important because no technology works if you can't afford it.

A powerful tool any technician can afford

Sprinkler solenoids can be checked using either activation or chatter modes. Lost or buried solenoids are quickly found as well by listening for the chatter or "chatterbox" function. Wiring can be verified and tagged with the built-in tone generator function. Clocks also are tested for proper 24vac output with a simple LED power check.

Made from a heavy duty plastic case, the highly visible yellow Pro48 sprinkler solenoid activator is designed for rugged use in the field.

  • Activates and holds solenoids open (including DC latching).
  • Generates and traces 1Khz tracing tone
  • Checks clock 24v power output
  • Tests for open or shorted wiring
  • Power Requirements: Two 9V Alkaline batteries (not included)
  • Battery Life: 3 hours continuous
  • Voltage Output: 36VDC peak
  • Voltage Protection: 28VAC

This device located my buried irrigation valve.
Before buying this device, I had been unable to locate a buried malfunctioning irrigation valve and was somewhat skeptical this device would help me find it. The "chatter" setting on the device allowed me to pinpoint the location of the valve inside its enclosure that had been covered by a layer of dirt.

Must buy for irrigators
Little device is a life saver. I have located several valves on jobs that I would have never found without this. It makes the click pretty loud.

made life easier
I bought this item because after two days of pounding the ground where I believed the valves were located and not finding anything (valve covers) it was the logical choice. The PRO-48 caused a chatter on the solenoid that I was trying to find and I located the sound; the sound echos and it was a little more difficult locating the sound source. I used it twice to located two groups of two valves and repaired my system.

Great Tool!
It was PERFECT! Directions were readily available and easy to follow. I was able to chatter and locate my abandoned valve in 5 minutes.Worth every penny!

Not good
I bought this device mainly to use the chatter feature to locate lost valves. I wanted to see how loud it made a valve chatter so I located a known valve and hooked up the leads to the common wire and the valve wire. I had to take the lid off of the valve box and put my ear about a foot from the valve before I could hear it chatter. I then went the old route of locating a lost valve by tracing the wire with my locator and probing the ground (which always works). The unit works great on shorts or testing to see if a solenoid is good or bad. I also could not get it to activate a valve.

hello! was wondering if solenoid chatter is ALWAYS audible by ear?
A shopper on Mar 23, 2012
BEST ANSWER: As long as the valve is not buried really deep. 9 out of 10 times I can hear it right away as long as I am in the general area of the valve. You will hear a click, click, click. (Also remember to cut off the water to the sprinklers first)
I will always have one of these with me when doing my sprinkler repairs!
I have a sprinkler valve that appears to be defective. Will this meter enable me to locate the valve?
Gary M on Mar 1, 2017
BEST ANSWER: If the solenoid functions properly, i.e. The coil causes plunger to move up and down then the pro 48 should cause the solenoid to produce enough noise to be heard. Unless of course the valve and valve box is covered by too much dirt and or thatch and grass to be heard. You may have to crawl around on your hands and knees with your ear to the ground. Been there done that. A pro 700 or 800 would be the better choice to locate the lost valve.
I rented a unit that retailed quite high. It found wires real good. It did not locate any valves after trying all day. Does the chatter box really find valves?
My valves are apparently about 2 feet deep. I need help locating the valves since the originally owner did not leave a map, if he even had a map. My thanks in advance for your help.

BEST ANSWER: Armada PRO-48 is a great tool for locating solenoid valves, I have successfully located hundreds of valves with this product. The Armada will only chatter solenoid valves that are in working electrical condition, including the field wire. If the valve will activate form the controller the armada will chatter the solenoid.

If you think that the valve is deep, it’s helpful to use a wire locator to track the wire path to determine a general location of the valve. I have located valves up to a foot deep with no problem. The only drawback is that the Armada chatter can be difficult to hear in noisy environments.
Where can I rent this unit? I live in Bradenton, FL.
Dick P on May 2, 2014
BEST ANSWER: I have never seen this particular unit for rent at any of the irrigation supply companies. However, you can rent similar valve locator or wire locator units. They usually rent for less than $50 at any irrigation supply house and/or tool rental company.

The Armada Pro-48 Chatterer has some advantages, but the valve locators offer an audible "beep" to follow the wire from the controller to the valve. They are more user friendly. The Chatterer might not make a loud enough noise to find the valve and if the solenoid is bad, they don't chatter at all.
do you have any franchise in UAE?
