Seventeen ideas, each one taught twice. Where a side says not filmed yet the clip does not exist, and the gap is left showing rather than papered over.

Direct connection, induction, capacitance, clamp, and what each one is for.

Sygma’s own webinars and training recordings, whole. Longer than most people want in one go, which is why the clips above exist, but this is where the full argument lives.

3:44:52The seminar, start to finishHigh End EM Locators: RD8000, RD8100 and vLocPro2The top end of the locating kit and what it does that a basic set cannot: signal strength and current measurement, what those numbers tell you when you are stood over a line, and the pipeline corrosion work these instruments are built for. Pete Ashcroft and Steve, in full.2:09:53The seminar, start to finishAdvanced Signal Application: Connection, Clamp, Induction and Frequency ChoiceThe advanced session on getting a signal onto a line and keeping it there: the four ways in, which frequency to choose and why, aerial configurations, and the tracing techniques that follow from each.1:56:21The seminar, start to finishHigh End EM: Frequencies, Connections and Current DirectionMulti-frequency locators and what changes when you move up to them: frequency selection, distorted fields and what causes them, connection technique, and reading current direction to know which way the signal is running.1:48:39The seminar, start to finishHow a Utility Network Works, and What the Plans and Marker Plates Tell YouHow the supply actually gets from the power station to a house, the cable types you meet on the way including old Hessian, and how to read a stats plan and a utility marker plate for what is really under your feet.1:26:46The seminar, start to finishEarthing, Clamping, and the Limits of InductionWhere the earth goes and why it matters, connection angles at 45 and 90 degrees, double ended connections, and an honest account of what induction will and will not do for you.1:20:50The seminar, start to finishCAT Manager: Getting the Data Off, and Telling Good Data From BadHow to pull usage data off a CAT4 and what to do with it once you have it. Which models record what, how to read the raw data, and how a supervisor tells a proper scan from a box ticked.1:12:19The seminar, start to finishGetting the Best Out of Your Genny and CATThe full webinar. Signal application from first principles: why you start with street lighting, the two ways lighting is wired, dual frequency, earthing the transmitter, induction against direct connection, and where the signal actually goes once you have applied it.1:07:19The seminar, start to finishGetting the Best From a Genny: Connection, Clamp and InductionA full run through signal application: the site survey first, then direct connection, the signal clamp and induction, with street lighting worked through including how a looping in and out system behaves.52:24The seminar, start to finishWhat Happens in a Cable Strike: LV, HV and the Person Holding the ToolWhat actually happens when a cable is struck, the difference between low and high voltage, where the earth and phases come into it, and what HSG47 requires of you before the ground is opened.48:20The seminar, start to finishCAT4 Data Download: Reading the Usage HistoryDownloading the usage history off a CAT4 and reading it: which models in the range hold data, how to get it out to CSV or KML, and what an avoidance scan looks like in the record.47:01The seminar, start to finishPower and Radio: What the Passive Modes MissWhy passive scanning is not enough on its own. What Power and Radio modes can and cannot see, why the same cable answers differently at different times of day, pot ended cables, and what the twin aerial design is doing.40:11The seminar, start to finishWhat Happens If You Hit a CableThe consequences of striking a cable, overhead and underground, the path of least resistance through a person, and the injuries that follow. The reason the locator comes out at all.27:07The seminar, start to finishReading Utility Plans: Loop In Loop Out, Teed Off, and Tracing HVGetting what you need out of a utility plan before the kit comes out: how street lighting is wired either looped in and out or teed off, what the voltage tells you, and the pre-planning that decides where you connect.9:40On site, start to finishGenny and CAT Training: The Full Run-ThroughThe whole method end to end in under ten minutes: pre-use checks, applying a signal, locating, pinpointing and taking a depth reading.8:52The seminar, start to finishOverlaid and Compiled Plans: Why They Invite AssumptionsWhat a compiled or overlaid drawing hides that the individual stats plans show. Pete Ashcroft on why one tidy drawing of everything is more dangerous than several awkward ones.

Short clips,kept for the sound.

9 clips

Reference recordings that do not belong to one teaching idea: mostly what the kit sounds like when it answers, which is easier to learn by ear than from a page.

01

Power Mode Problems: What It Sounds Like On Site

A CAT running in Power mode on site, recorded so you can hear the response and where it becomes hard to trust.

02

How the CAT Signal Changes Over a Buried Line

A sweep over a buried line with the audio kept, so you can hear the response build and fall away.

03

Locator Tones on a Practical Exercise

A trainee being talked through holding the locator steady, with the tones it produces.

04

The CAT Answering on a Signal

Six seconds of a locator on a signal, kept as a reference for the sound.

05

The Pitch Change as the CAT Crosses a Signal

Audio only: the way the pitch and tone move as the locator crosses a signal.

06

Tracing a Buried BT Line

Following a buried BT line on site, and what the locator gives you while you do it.

07

What a CAT Sounds Like Over a Buried Service

A short recording of the locator answering over a buried service, kept for the sound of it.

08

What Picking Up a Signal Sounds Like

A locator answering at the roadside, recorded with the traffic still going past.

09

What the Locator Tones Sound Like On Site

A field exercise recorded for the sound: how the CAT and the Genny answer, and how the tone shifts as the locator moves.
