Updating the Mammut Pulse Barryvox

Mammut Pulse Barryvox Avalanche Beacon
Mammut Pulse
Technical noteThe 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 page).

Version Enhancements
Version 4.0
Fall 2013
  • Expanded first signal display. A new algorithm allows for increased range during the signal search 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 Advanced mode) guides you through this process and reduces errors commonly seen in rescue practice. This promotional video illustrates the "Guided Fine Search."
Version 3.2
Fall 2011
(Still the current update as of Fall 2012)

The following features were added to the 3.2 firmware update:

  • Directional Tones. The Pulse's (and Element's) audio tones change based on the direction indicator. Learn more about this feature here.
  • 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 fine search between a "landing strip" (forward and backward only) and a "cross fire." Learn about the "landing strip" approach here.
  • 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
Fall 2009

(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 here).
    • 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 reception range.
  • 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 signal search through coarse search
    • Protection against accidental switching from Search to Send
    • There has been a significant reduction in the number of “Please stand still” and "Hold device horizontal" messages.
    • 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
