Pro881 is an affordable digital underground cable locator to easily find lost valves and broken or severely damaged wires, as well as trace their paths. It is excellent for locating different types of cabling, including irrigation, CATV, electrical, telephone, and lighting, as well as faults in them.
Pro881 is an affordable digital underground cable locator to easily find lost valves and broken or severely damaged wires, as well as trace their paths. It is excellent for locating different types of cabling, including irrigation, CATV, electrical, telephone, and lighting, as well as faults in them.
The Armada Pro881 underground cable locator consists of a transmitter with a broadcasting antenna inside and a receiver that tracks irrigation wires, valves, and finds major faults in cables. The transmitter is the long gray box that also serves as the carrying case. The receiver is the black and yellow wand.
The Pro881 transmitter features 3 different locating frequencies, 2 kHz and 33 kHz in direct connection mode, and a broadcast frequency of 175 kHz via the clamp or internal broadcast antenna.
The 2 kHz and 33 kHz in direct connect mode – are used to facilitate more accurate tracing or to gain more distance. The total distance in direct connection mode reaches up to 5,000 feet, and the locating depth is up to 8 feet.
The broadcast frequency of 175 kHz via the clamp or internal broadcast antenna is widely used to scan any area before digging, just to find out if it’s safe to start excavating in the area. Broadcast mode is connectionless and different from using the direct clip-on method of connection. It is not as precise or strong as direct connecting, but when access to cables is limited or just a quick scan is required, broadcast mode can be very useful.
The Armada underground cable locator Pro881 finds cables in 3 different ways. First, via direct connection, while the transmitter is connected to a cable, it sends a signal of either 2kHz or 33kHz onto the cable, and the locator will react to that cable.
Second, when the inductive clamp is connected to a cable or conduit in which the cable is placed, the signal will be induced into the cable. This mode is very useful when there is no direct access to the target cable.
The third is the broadcast mode - the inductive antenna sends a signal to the ground where cables are located, and the locator will map out cables and pipes present within the surrounding area. This mode is very useful for most construction work when the user wants to determine the presence of any cables within a construction work zone.
These wireless connection methods of the inductive clamp or inductive antenna give the Pro881 incredible flexibility when tracking wires and cables that you either can’t or don’t wish to disconnect, like live electrical or in-service CATV lines.
Features
There are two receiver wand modes for tracing a path: Null or Peak. The receiver defaults to Null when turned on. The user may select which mode is the best for their application. The receiver and transmitter must always be in the same mode to operate properly.
The knob on the receiver control panel regulates the volume level of the receiver for both headphones and external speaker. Additionally, the signal LED group on the receiver display will indicate the signal level visually. After connecting and turning on the transmitter and the receiver, point the receiver toward the ground in the direction of the cable and listen for the beeping signal. The feedback of whatever you are locating is given in two manners: audible external speaker and headset. These audible options indicate the signal strength that is being received by the Pro881™.
The Armada wire locator incorporates digital reception filtration to eliminate unwanted AC noise and interference for efficient, uncomplicated locates. This advanced cable locator provides a clear, clean, interference-free signal - no buzzing, no AC cracking, no drowning of your signal beneath the local electrical transformer or electrical cable. All the interference is filtered out. The user is able to clearly hear the beeping or continuous tone that is easy to follow and easy to track.
Locating in a noisy environment is easy, as the Armada cable locator comes with a stereo headset to listen to the tracing tone in addition to a standard speaker.
The Armada Technologies Pro881 can also be used to find breaks or severe wire damage. However, unlike when you are tracing a wire, the break or wire damage will cause the signal to stop at the point of the break. Either the speaker or the analog meter on the receiver will indicate this drop. Generally, the greater the damage to the wire, the greater the drop-off at the point of damage.
The Pro881 uses the triangulation method for depth determination.
Simply acquire the wire path in the null mode, place the receiver at a 45-degree angle to that path, move the receiver horizontally in the direction the receiver wand is leaning, and when you get the null again, the distance traveled is the depth of the wire.
The Armada Pro881 uses 8 “D” batteries installed in the transmitter battery compartment and a 9-volt alkaline or lithium battery in the receiver. Both the transmitter and receiver have an LED to indicate battery level.
