Active interference, or "noise", consists of anything that emits a signal that
interferes with the transmitter signal. Example sources include power lines,
radio towers, cathodic protection, fiber tracer lines, invisible dog fences,
security systems, and traffic signal loops. Falcon's frequency optimizer finds
the best frequencies to avoid noise.
Passive interference consists of anything that blocks or distorts the
transmitter signal resulting in incorrect depths or missing data. Example
sources include rebar, guard rails, bridge abutments, chain link fencing,
salt/saltwater, and soil high in metal ore. The Falcon sub-kHz transmitter
(available for Falcon F5 and F5+ only) helps cut through passive interference
without distorting the signal.
An A on the screen can indicate signal Attenuation due to the presence of
excessive interference, which can make depth readings inaccurate.
Attenuation is normal in shallow depths less than 8 feet (2.4 m). If the signal
strength is also flashing, this indicates extreme interference. Depth and
locate points may be compromised and the locator will not calibrate.
OPTIMIZE EVERY JOB
Noise varies by amount and frequency depending on where you are and
even the time of day. That's why it's important to find the best frequencies for
every bore .
This is called frequency optimization , and only Falcon has it. Using
frequencies with the highest probability of success against noise increases
locating accuracy and reduces the risk of tripping out.
Falcon's frequency optimizer scans through hundreds of frequencies, then
bundles those with the lowest noise into finely-tuned bands that work best
for the current job.
Select two bands and switch between them mid-bore if needed (not available
on the Falcon F1 with singleband).
