Mammut Pulse can be updated
through a wireless link. The ability to update your beacon is important,
because it allows you to get enhancements and new features without
purchasing a new avalanche transceiver. (Read
about updating other transceivers.)
Beginning with version 3.0, the version number is displayed on the
screen when you turn on the power. To check the version on earlier
versions, press either button shortly after turning on the unit
and then use the left button to scroll through the settings to Maintenance.
It costs $30us to update the Pulse. The update can be done at about
a dozen retail locations in the US and Canada as well as at the
Mammut service centers in Vermont and British Columbia. Visit the
Mammut dealer locator (be sure to select the "PULSE Barryvox
Firmware Update" checkbox in the lower-left corner of that
- Expanded first signal display.
A new algorithm allows for increased range during the
in certain situations (presumably 2-5 meters).
- Optimized direction display. Changes
to the internal compass reduce “jumpiness” in the directional
and distance indicators and guide the searcher along
a more direct path.
- Guided Fine Search.
During the fine
search, avalanche transceivers should only be moved
forward-and-backward or side-to-side, without twisting,
pivoting, or tilting the transceiver. The goal
is to move in a grid-like pattern, continuing in each
direction until the displayed distance increases, and
then reversing the direction until you find the minimum
distance along that path. You then repeat this process
on a perpendicular path until you find the minimum distance. The
Pulse’s new “Guided Fine Search” (one of three optional
settings for the final search phase in
mode) guides you through this process and reduces
errors commonly seen in rescue practice. This
promotional video illustrates the "Guided Fine
(Still the current update
as of Fall 2012)
The following features were added to the 3.2 firmware
- Directional Tones. The Pulse's
audio tones change based on the direction indicator.

- Rescue Send. This feature is targeted
at professional users: If you are in Search mode and
you switch directly to Send, the Pulse will ask you
if you prefer "Rescue Send." In this mode,
the Pulse is neither sending or receiving, but it will
revert to transmit
if it doesn't sense motion after seven minutes. This
basically mutes the beep-beep that would normally occur
while searching without transmitting a signal.
- Landing Strip or Cross Fire. This
changes the display during the Pulse's
between a "landing strip" (forward and backward
only) and a "cross fire." Learn about the "landing
- Lithium Batteries. Starting with
version 3.2, the Pulse can use either alkaline or lithium
batteries. Lithium batteries
are "considerably lighter" and will increase
the battery life by 30% to 50%. They also eliminate
the possibility of corrosion. You must choose the appropriate "alkaline"
or "lithium" option in the Pulse's settings
before changing the type of battery.
(Version 3.0 was the most
recent update for the 2010/2011 season.)
- The biggest enhancement in version 3.0 is the addition
of two user profiles (read more about this
- Basic profile is the "easiest digital search
for casual users"
- Advanced profile offers "analog and digital
search modes and customized settings"
- Version 3.0 is supposed to provide an increased
- More effective search functions
- Dynamic pinpointing display
The search arrow now grows/shrinks depending on
how close you are to the victim which provides another
indication of the distance to the victim (in addition
to the changing tone and distance display).
- Numbering of marked buried subjects
- Acoustic signal from
- Protection against accidental switching from
Search to Send
- There has been a significant reduction in the
number of “Please stand still” and "Hold device
- Variable size distance numbers. I.e., the size
of the integer and decimal portions of the distance
numbers make it easier to differential between numbers
such as 23 meters and 2.3 meters.
- Acoustic feedback when Send mode is activated
