You have purchased some of the finest locating tools in the business,
but they don’t do magic. Your skill at handling these tools and
recognition of their strengths and weaknesses is what makes a locating
job successful. Before taking them out on their first job, make sure
you understand how the system works.
What’s so special about “digital” tools?
Digital technology combines modern radio circuitry with
microprocessor control, allowing great versatility in the operation of
an instrument. What this means to you is tools that make judgments
from many sources of information and interact with you as the
operator to help lead you to fast, easy and accurate locating.
The following pages will take you through all the steps necessary to
understand and use your equipment. We strongly recommend that
you pay close attention to the section “Getting to Know your Tools”,
and come back to it whenever you are confused about the responses
you are seeing on actual locating jobs.
This advice applies whether you’re a rookie at underground locating or
an “old pro”. Prototek tools are extremely simple to use, and it’s easy
to outsmart yourself if you’re used to more complicated equipment and
procedures.

Please note: These instructions should be considered
guidelines, not gospel. Every locating job presents unique
challenges, and although most will yield to “textbook”
procedures as described here, many will require a creative
approach. We strongly advise that you familiarize yourself
with the fundamentals of digital locating as described in
the section “Getting to Know Your Tools”. Armed with this
knowledge, you will be able to reason your way through most
locating challenges.
The LF2000 is a powerful and
durable receiver that is also
remarkably easy to use. Locates any
512 Hz sonde in cast iron or non-
metallic lines. Uses 6 off-the-shelf
AA alkaline batteries. A clear clicking
sound provides intuitive feedback on
signal strength – the faster the click,
the stronger the signal. Clear LCD
screens (with automatic backlight
compensation) guide you through
the steps critical to locating with
accurate position as well as precise
depth. Handle vibration at key
locating points enables fast, safe
“heads-up” locating.
