Navitrack locators are the essential advantage of the Ridgid systems. Combined with the Seesnake I think it’s an almost unbeatable package.
Navitracks are trouble free and reliable. Some of our guys use the smaller Ridgid Scout locators and like them but in my opinion, Navitrack is more comfortable. I like that it’s bigger when you’re using it, you don’t have to hunch over to get it close to the ground. It provides depth info on lines deeper than the Scout can give and the larger screen is better for eyes. The display on the Navitrack II can be a little intimidating at first but it’s not that complicated.
With Navitrack you get a big monitor, a visual “map” and direction (after you have located poles and the active sonde). You are able to just point in a direction and get an idea of things.
The Navitrak II Locator is fantastic…
I had guys doubting my locating work and calling me to digs…
One job I had marked it and said 6 1/2′ deep…
I don’t know why they were complaining that they couldn’t find the pipe at a depth of 6’…
It was there…Redwood, draincleaningforum.com forum
Sewers are rarely (IMO, less 5%) deeper than 6 feet so Navitrac II is probably overkill for most plumbers. Once you get the hang of a Navitrack, it’s tough to go back to a Gator or something else.
With the Navitrak II you walk outside to either the back or the front of the house where you think the line is located. Then hold it out in front of you and turn in a circle. Look for the strongest signal then point it down and walk in that direction to locate the 2 poles of the transmitter which are displayed as crosses on the screen centering and marking them. Then walk straight between those marks and watch for the null bar to center then with the locator in a straight line and the null bar centered on the display Mark the spot and get the depth information which is displayed in feet and inches to indicate the depth of the camera. Of course if it is sitting on the bottom of a 10″ line that should be considered. This works as long as the line is level or, normal pitch. If the line is dropping at a 45° or, vertical it gets a bit more complicated.
The method is accurate enough for pretty much anything we do and there are more complex options which can yield more in depth information if desired. Typically an accurate locating with depth takes less than a minute.

For just finding a sonde in a camera head the scout is dummed down to make it simple to use. So if just finding 512 sondes the scout is easy to use for a first timer. If the pitch of the pipe is steep it will make some problems for the Scout locator. May be the problem it is a rather steep grade to the septic tank.
If you always work in 512 sonde mode, you are missing a lot of Scout potential. You can check buried power lines in the freq menu when unchecking 512 mode then selecting 60hz and walk around until a line appears on the screen. If it is solid and not fuzzy you have likely found an energized line! If there you have a fuzzy (distortion) line try to move back and forth to see if it becomes clear then follow it. Distortion lines are important also and they can mean a lot of things. For example, you could be crossing over another line like cable or phone line and the signal is jumping over to them. In this case you may have just found additional line while you were looking. The Scout indicates the direction to start traveling following a line. It gives really pretty accurate depth.
If you have a transmitter to use, Great! With the transmitter you can trace the signal you are putting out. Set the Scout and the transmitter on 33 MHz and you can trace now whatever you put the signal on. Usually, the spot where you clamp onto within 3 feet will have a high distortion ratio. To get good readings, you need to move away from the box.
Even if you don’t have a camera, with a scout and a cheap small transmitter you have an opportunity to diagnose lines. Let’s say you have a really bad sewer drain and you can only get 66 feet out. The bits are not anymore coming back with roots, but now they seemed grinded on (shined up) And you may say “I think your line has a bad offset joint or is broken, you need to call someone else” But if you took a few minutes and connect your transmitter to your snake and used the scout you could find the spot where the problem is and know the depth! If it was just a few feet down in a soft soil, you could take the job on and don’t give it away to someone else with a sewer camera.
If you own a Scout, you must find out what all the buttons do! Make some shallow tests, walk around your neighborhood to gain hands on use. Find gas lines, water lines, sewers, sprinklers, power cables. The practice will just make you better specialist at what you already do.
The locator has a micro-mapping display to mark distinctive poles in front of and behind the target. Depth is calculated automatically and displayed when over the target.
