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 F and F + 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 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 F with singleband).
The Falcon locators with
Quick Scan Pair
offer features to make the selection
of bands faster and easier. Two clicks select the two preset bands selected
for your region.
