Searching: The Neo has a suggested search strip width of 60 meters—similar to the DSP Pro. In my limited testing, the Neo's range exceeded the Pro's by a few meters.
The Neo displays an LCD direction arrow which can be set to disappear at either 3 or 5 meters to facilitate the fine search. If you are walking away from the transmitter (which is likely due to the way flux lines propagate), the Neo will display a U-turn arrow instructing you turn around.
Spikes: Spike handling was flawless.
Multiple Burials: The Neo displays up to three silhouettes on the display to indicate the number of transmitters. A plus sign appears when there are more than three transmitters.
When you are within 3 or 5 meters (a custom setting), a flag icon blinks in the upper right-hand corner of the display to let you know that you can flag that transmitter. Pressing and releasing the intuitive Flag button will ignore the closest beacon and direct you to the next transmitter. A flag will appear next to one of the men. If you attempt to flag a transmitter when you are too far away, the word "no" is displayed on the screen. To unflag the previously ignored transmitters, toggle the Neo to Send and back to Search.
Although I have done minimal testing of the Neo's flag command, the transceiver's use of a consistent image (i.e., a flag) when you are within range, on the button, and next to the flagged silhouettes is very intuitive.
Controls: The Neo's controls are as simple as it gets. The power is turned on when you connect the harness' "plug" (although oddly, you connect the plug by twisting it counter-clockwise), A mitten-friendly sliding switch changes the transceiver between Send and Search. A single "Flag" button is in the center of the device.
The Neo is one of the few avalanche transceivers that does not have a blinking light that shows that it is transmitting (and which would be visible when in its harness).
It's worth noting that the Neo's speaker is loud. Really loud. Aging patrollers who have spent years playing with avalanche explosives will appreciate this.
Group Check: During startup, the Neo displays its firmware version, the battery percentage, and then "CH" (for CHeck) for several seconds. Pressing the Flag button while CH is displayed enters the Neo's group check mode (that's not intuitive). While in group check mode, the Neo beeps if a transmitter is between 0.5 and 1.5 meters. If you get closer than 0.5 meters, it beeps loudly. You can turn off the group check mode by pressing the Flag button.
Revert to Transmit: The Neo can be programmed to automatically switch from search mode to transmit mode if 2, 4, or 8 minutes pass without receiving a signal. Auto-reverting is helpful to ensure that you will be transmitting if you get buried by a second avalanche. The downside of auto-reverting is if a second avalanche occurs while you are searching, it's likely your transceiver will be torn from your hands and your buddies will waste time digging up an unattached transceiver. The Neo gives a loud audible warning before reverting during which you can press the Flag button to continue searching.
Comfort: The Neo has a neoprene pouch harness with a Fastex closure. You can remove the connector "plug" from the harness and install it on the leash so you can use the Neo without a harness. The Neo is a little larger and heavier than similarly featured avalanche transceivers.
Updates: The ARVA Neo supports software updates. Read the details here.
Customizing: You can specify the number of minutes before the Neo will revert to transmit (specify 0 to disable this feature), the maximum distance where you can flag a transceiver during a multiple burial (either 3 or 5 meters), and whether you want to enable or disable the group check mode on startup ("1" enables and "0" disables).
