Those systems start at $12K on up for new. And the sondes are pretty large. Yes they would work better if you are rodding 1.25” duct or larger. They also will not take corners like a shorter beacon.

I am going to need to try to find an adapter to connect it to my rodder. https://shop.leica-geosystems.com/buy/accessories/duct-sonde-33 Steve, I've seen the flushable sondes and wondered why they cost $35 when the regular ones cost $400 to 1K+. Can't seem to find them in 30kHz or 640hz which is what our existing 150R locator says it supports.

I think it was ~3000 retail. As to its accuracy, based on my one time usage last week I spotted the drill sticks 100% and got the distance within inches. My locator tech says it's 100x better than the old one when there's noise (nearby other utilities).

I'm at the point where I just need to make a decision but 4K isn't enough to make the decision I want to make. On Tue, Dec 27, 2022 at 5:07 PM Chuck McCown via AF <af@af.afmug.com> wrote: Most if not all of them locate the signal based on current flowing on a conductor. So you put a signal on a trace wire or cable shield. Ground the far end. The transmitter is connected to the cable and a ground rod. That flow of signal sets up the magnetic field and that is what the locator works off of. If you have trace current then all of them will do a good job. The type of soil doesn’t make much difference. The super cheap ones will find it as easy and the super expensive units. Finding a reliable depth is more difficult. The only brand I have every used where I could trust the depth was a Metrotel. But even the cheapest unit can find depth by locating a null, orienting the pick up coil at 45 degrees and then finding the null off to the side of the of the cable. Distance from the center null to the side null is the depth. The higher the power the farther you can locate. But that just means you don’t have to move the transmitter so much. In my experience I am generally within a quarter mile of the transmitter or less and all of them will do that distance. Some of them will also passively locate 60 cycle power. Some of them locate based on radio signals picked up by wires and pipes and re-radiated. I have had limited success with that on high pressure gas. Many of them have an RF mode where you connect to some object to track but the far end is not grounded. So you just have a capacitive coupling between the thing you want to locate and the earth. Not much current flows so you do not get much distance. For example a fish tape down a plastic duct is located this way. But you will only get dozens or perhaps hundreds of feed if you are lucky. Multiple frequencies have their uses. Older units were down in the audible range like 800 Hz. You can go a very long way with those frequecies. But they also bleed off to other cables and pipes. Higher frequencies are better to get finer resolution but they do not transmit as far. 82 or 84KHz is a popular frequency. Some brands put a coded signal out so only their receiver can pick up the signal. Rycom is one of those.

Trying to do this with a 4K budget. Is a locator either good or bad or is there a middle ground where they don't work well.

SPX25 is good for locating shallower thing. stuff like the 10x15 or 20x22 utility locator are surprisingly accurate for it having to be pretty pinpoint. But if you really want to be certain about finding the utilities on a smaller ISP budget, youd want to look at Bobcat brand locators, those will find everything.
