Summary: The now-discontinued ARVA Axis was the fewer-featured little brother to the
ARVA Pro W (aka Link). This followed the trend of the
Pieps Tour (the fewer-featured little brother to the Pieps
DSP) and the Mammut Element (the little brother to the
Mammut Pulse). I own, but have not fully tested, the Axis.
(Don't confuse the ARVA Axis which was released in 2011 and discontinued in 2013 with the
ARVA 3Axes which was discontinued in 2011.)
The easiest way to describe the Axis it so say that it is identical to the
ARVA Pro W with these exceptions:
- When searching, the Axis can point in 5 different directions while the Pro W has a freely-floating
arrow that is based on a compass (similar to the Mammut Pulse).
- When searching for multiple transmitters, the Axis always
takes you to the nearest victim whereas the Pro W allows you to select from a list of victims.
And the Pro W allows you to "unmark" a specific victim whereas the Axis requires you to toggle
between search and send modes to unmark all victims. (The Pro W's additional options do add a little
complexity.)
- The Pro W, but not the Axis, uses data that is transmitted on the "w-link" frequency by the
Pro W or Mammut Pulse to improve marking when searching for multiple transmitters.
- The Axis has a neoprene case with thin harness straps while the Pro W is stored in a large,
semi-rigid holster with a wide shoulder strap.
- The Axis is white with black "bumpers" on the housing whereas the Pro W is white with gray
bumpers (the Pro W's predecessor, the Link, was all black).
- The Axis was priced $90.00us less than the Pro W.
Using the big-brother little-brother analogy, it's notable that ARVA chose to keep many more features
in their little brother (i.e., the Axis) than Mammut and Pieps chose to keep in the Element and Tour. For
example:
- The Axis can be toggled between analog and digital modes whereas the Element gave up this feature
from its big brother.
- The Axis retains two buttons whereas the Element and Tour eliminated one of their buttons.
- The Axis (and Tour) retained its lighted display whereas the Element gave up this feature.
- The Axis senses motion before reverting from searching to sending
whereas the Element gave up this feature. The Axis also lets you specify how many minutes must elapse
before it auto reverts whereas this feature is found in the Pulse but not the Element.
- The Axis retained its earphone jack whereas the Element didn't.
- The Axis retained the ability to customize its startup screen whereas the Element didn't.
Many of the features that were retained in the Axis, such as the customizable startup screen, the lighted
display, and the earphone jack, add benefit without adding any complexity. Even the ability to toggle to
analog (by pressing and holding both buttons) adds significant power yet can be completely ignored. The
one feature that was retained in the Axis and which does add a complexity is the two side-buttons. Whereas
the Mammut Element and the Pieps Tour have one off/send/search switch and one "mark" button, the Axis has
an on/off button, a search switch (with an "Enter" button in the center of the switch), and two side-buttons.
It's easy enough to learn how to use the Axis, but it isn't as easy as the Element and Tour.
