Pieps DSP was replaced by the
Pieps DSP Pro in October
2013 after Pieps was acquired by Black Diamond Equipment.
Black Diamond also lowered the price by $75. (This "original"
DSP will be available in a package with a shovel and probe
for until the inventory runs out, but for practical purposes
the original DSP has been discontinued.)
Summary: The Pieps DSP (not to be confused with the
DSP Sport, or
DSP Pro)is a small beacon,
it has one of the longest
ranges of the digitals, it allows you to lock-out a
transceiver during a multiple
burial, its third antenna
is excellent at dealing with spikes
during deeper burials, it handles
frequency drift well, and it
can be periodically upgraded
with newer features.
Pieps Tour is a nearly-identical twin to the DSP, but
the Tour has only one button, three fewer features, and
a lower price tag. The
Pieps DSP Advanced included the same features as the
Pieps DSP plus it added a temperature display, compass,
and barometric altimeter. The Advanced was discontinued
Searching: The DSP has a long
range and an intuitive
The direction indicator refreshes slightly slower
(although I haven't quantified this or adequately compared
it to the Pulse).
As with most transceivers (the exceptions being the
Mammut Pulse, and
the Mammut Element),
if you are headed in the wrong direction (which can easily
happen, since transceivers simply align you with the transmitting
beacon's flux lines)
you will need to notice that the distance is increasing
and turn around.
Multiple Burials: The handling of
multiple burials is similar
to other digital transceivers: you press the Mark button
to ignore the current beacon and advance to the next beacon.
(The DSP and Tour require you to press and hold
the button.) The DSP also has a Scan function that
will display the number of transmitters within 5, 20, and

Spikes: The Pieps DSP was the first
three-antenna beacon and set
the standard for spike handling.
Controls: The switch that changes between Off,
Send, and Search is the most intuitive of the 30 beacons
reviewed. A bump of the switch changes from Search back
to Send. The Mark button (a flag, which is reasonably intuitive)
tells the transceiver to ignore the nearest transceiver
during a multiple burial
Due to the magnetic switch
in the original (yellow) DSP and DSP Tour, it is possible
for a large radio or for magnetic jacket closures to turn
off the Pieps (details
Comfort: The Pieps harness is now on its third
generation. The original black and subsequent silver harnesses
were far from ideal. The new harness is a very comfortable
pouch-style harness. The latest DSP harness can be purchased
separately from Black Diamond.
Other Features: The DSP lets you
transmitting frequency of your friend's transceiver.
It has a "Smart
Transmitter" which modifies the cadence of the
transmitted single to reduce the likelihood of signal overlap
during a two-victim multiple burial. The
shows the distance to multiple victims.
Version 5.0 and newer versions
of the software supports the
Version 8.2 and newer versions
of the software supports the
TX600 Dog Transmitter.
The Pieps DSP is programmed to
blink the little man icon ()
at the bottom of the screen when it senses a
continuous background signal (i.e.,
an older analog beacon). To test this, I searched for an
M1 which had a strong background signal. The DSP's
man icon did not blink during the
but it did display two blinking men during the
fine search. I treat
the blinking men as a indication that the DSP is aware of
an unusual signal and is trying to interpret it.
Upgrades: The DSP can be upgraded via the earphone
jack. Read about the latest software updates
Other: Read about the DSP's
self-test. The Pieps warranty
only covers the DSP for 2 years unless you register it within
three months of the date of purchase, in which case the
warranty is extended to 5 years.
