Today Ortovox officially added two new avalanche transceivers to the market, the Diract and the Diract Voice. While a few preproduction samples have been checked out by other avalanche professionals I received a post production model about a week ago and want to share some preliminary opinions and thoughts at this revolutionary avalanche transceiver. A more in-depth review will be published after I’ve had some considerable real world field time with this model. I know a lot of people may be looking for a new avalanche transceiver before the snow really starts to fly and I hope this “first look” report will help you decide if you should consider the Ortovox Diract or Ortovox Diract Voice avalanche transceiver!
After unboxing the initial set up was straight forward. As soon as you open the box instruction on the lid include a QR code directing you to download the Ortovox app for either iOS or Android. I selected English from the nine available languages and register the device through the app while synced to my smartphone via Bluetooth. Registration is a great idea since not only will up be sure to receive any important software update notifications it automatically extends the two year warranty by an additional 3 years giving you 5 years of total protection on your investment! More information and links to the apps along with some video tutorials can be found here: https://ortovox.com/us-en/service/information-user-manuals/avalanche-transceivers/diract-start
After registering the device I was instructed to calibrate the internal electronic compass used to ensure the device is held level in SEARCH mode and to analyze orientation when buried for the “Smart Antenna” technology (more on that later). I chose to do this outside in the yard away from the house and my cell phone to ensure no interference.
Let’s start with the obvious biggest feature of the Ortovox Diract Voice. This is the first ever avalanche transceiver that gives the user verbal feedback during the stressful times of an avalanche rescue. Like others, I wasn’t exactly sure about the name Ortovox chose for this new model, but a quick Google Translation search revealed that “diract” is the Hindi word for “direct”. And that is what this avalanche transceiver attempts to do… direct your actions during the course of an avalanche rescue with important voice prompts. I demonstrate this in this video with some initial hands on practice in a nearby field:
POST PRODUCTION NOTES:
While filming the first couple test runs with my iPhone in AIRPLANE mode the transceiver experienced electronic interference which caused a false signal while outside the range of the transmitting transceiver and caused the transceiver to instruct me to start a fine search while still 18 meters from a second transceiver. Both of these errors were user-error, not software error! Any electronic with a GPS chip, Bluetooth, WiFi, radio transmitter, or microchip, should be more than half a meter away from a transceiver in search mode, or better yet powered off completely! I’ve left these first test runs in the final video as they demonstrate how the voice commands work and I believe that is useful. Twelve more test runs were conducted (6 filmed by the drone) and no other errors were observed.
My overall impression of this novel idea is positive. As an avalanche course instructor with over 100 avalanche courses taught I really do believe voice prompts can help rescuers react appropriately. Reminders like the initial “Run in 50 meter search strips and look out” encourage both urgency and situational awareness. Directional corrections like “run to the left/right” can help keep the searcher on the “flux line” while they are constantly conducting a quality visual search (often a part of rescue new rescuers struggle with). Getting outside of the fine search area the transceiver clearly tells you “You were closer!” When I publish my updated full review (ETA mid-winter) I will cover every voice command that’s possible and how best it fits into the rescue strategy.
There is one voice command I would have liked to have seen integrated. If the transceiver registers a number less than 1 meter during the search I would have loved for it to tell me to “Start probing here!” I have observed for years students will spend too much time on the fine search trying to get the lowest possible number when in reality if they are actually searching for a human sized target (and not a small stuff sack) and have a number under 1 meter they should halt the fine search and start probing. A probe strike is imminent. In that same line of thought it would be great if the transceiver could tell a quality fine search was carried out and if 1.6 meters in the lowest number after the fine search it could also direct the user to start probing.
That said a practiced rescuer should be able to make these transitions without the voice command, so the omission of this one command is no deal breaker!
Internal Lithium Ion Rechargeable Battery
The next biggest innovation in both the Diract and Diract Voice is the use of an internal lithium ion rechargeable battery. I think this is a great choice from a design point and I’m confident other manufacturers may follow suit as there are few disadvantages and many advantages. First of all having an internal rechargeable battery means no more pulling half used alkaline batteries out when they reach 60% and adding them to the draw of “not full batteries” I have in my gear room. This is better for the environment. The next advantage is you do not need to remember to remove your batteries at the end of the winter season. I’ve seen quite a few transceivers ruined with corroded batteries when owners left their batteries in them over the course of a humid summer. With this style battery it is best to not constantly “short charge” they battery, i.e. plugging it in every night to get it back to 100%. The user manual states to not charge until under 80%, and even states “once the battery charge falls below 40%, the device should be charged as soon as possible”.
The technical specifications claim that a full battery will provide a minimum of 200 hours in SEND followed by 1 hour of SEARCH. I will do some extensive testing of this battery over the next month and update this post accordingly by for now I’ll say I’m quite confident in this performance. After 2 hours of SEND and about 30 minutes of SEARCH my battery is still reporting 100%. Depending on how often you tour I imagine you’ll only need to recharge once or twice a season. I will be teaching rescue skills weekly from December through March and will report back detailed battery performance.
As for concerns about not being able to access or self-replace the lithium-ion battery Ortovox has had a third-party verify that this battery is good for at least 450 “cycles” and will still produce enough power to meet the 200 hours of SEND followed by 1 hour of SEARCH performance. A “cycle” is basically each time you charge the battery, which is why “short charging” is discouraged. Ortovox is working on a consumer focused solution for when it does become time to replace the battery, which based on my estimates of heavy use, won’t be needed for 5-7 years, if even then. The truth is with these numbers and proper charging habits the battery may last as long as the widely recommended “upgrade/replace your transceiver” suggestion of ten years. If that holds true that equals about 30-60 AA alkaline batteries from my own use staying out of a landfill!
The software is designed to self test the battery at every start up and will display a percentage, along with a alert if 30% or less, or “empty”. It also checks the health of the battery so if you ever do reach the end of the life of the battery it will display “Battery service necessary” and direct you to the Ortovox website for service/repair.
Finally it should be noted that you can not charge the battery when it is under 0 degrees Celsius. This may concern some users but I feel with proper planning this should never be an issue. My plan is to let my battery deplete for during day trips to within 40-50% capacity then recharge to full (one cycle). If I am heading out on a week long trip somewhere (Iceland this April?) I’ll recharge it to 100% for the trip. If you are spending two months on some amazing expedition I’m sure you can get the transceiver above 0 degrees Celsius in your sleeping bag if you need to recharge it.
Standby Mode and Auto-Revert
The next unique feature of the Ortovox Diract and Diract Voice is the addition of a “Standby” mode. Typically avalanche transceivers have only two modes, SEND/TRANSMIT or SEARCH. In a rescue scenario we teach everyone in the group not caught in the avalanche to switch their transceivers to SEARCH so that rescuers don’t waste time by “finding” people who are not buried in the snow. The issue is in a group rescue scenario you often do not need 5 people searching for a signal on a debris pile. For example if one person is missing and there are 5 rescuers you might only have 1 or 2 people actually searching with their transceivers while the rest of the group spots from a safe location and starts assembling probes and shovels to be ready for the extraction part of the rescue. These rescuers can utilize the standby mode to get their transceiver to stop transmitting, and, especially in the case of the Diract Voice, quiet the scene. We don’t need all the beeping and voice commands confusing the overall scenario. While in Standby mode the transceiver does have a motion sensor that is monitoring your movement. If no movement is detected in 90 seconds a loud alarm and display warning will indicate the unit will revert back to SEND in 30 seconds if 1) no movement is detected (i.e. you were caught and buried by a secondary avalanche), or 2) You press the FLAG button to cancel the revert.
The next thing I’d like to talk about is the shape and layout of the unit. Applicable to both models these transceivers are a slim design that fits comfortably in my hand and in my dedicated transceiver pocket on my ski pants. While I traditionally prefer to pocket carry my transceiver I believe I’ll start using the harness carry more often due to some innovative choices by Ortovox. The first is the decision to move the Recco technology from the transceiver to the carrying system. The second is the harness pocket holds the transceiver perfectly and adjusts with ease.
The layout of the controls is simple but well thought out. I am able to operate all functions on the transceiver with one hand regardless.of using my dominant (right) hand or not. With only two buttons and the SEND/SEARCH switch operation is really intuitive. To test the intuitiveness for a non-trained user I asked my 10 year old son to turn the transceiver on, put the unit into SEARCH mode, return to SEND mode, and power off the device. He accomplished all four tasks in less than two minutes with no further instruction.
Smart Antenna Technology
A feature of all Ortovox transceivers I have long been a fan of is the patented “SMART-ANTENNA-TECHNOLOGY ™. This basically makes locating your signal faster regardless of what orientation the transceiver is buried in by using intelligent position recognition and automatically switching to the best transmission antenna. Ortovox transceivers are the only transceivers that use this technology and I believe it’s an excellent feature.
The LCD display is quite visible in bright daylight and the brightness is adjustable via the free Ortovox app. I’ll be leaving it on the brightest setting while testing the battery performance this winter. The screen has a smart light sensor so when the transceiver is stowed in either a pocket or the carrying case it will shut off. After removing it from the harness a quick press of either of the two buttons will waken it.
Range and “smart” Search Strip Width while in SEARCH
I tested the Ortovox Diract Voice in an open field with a measured distance with the following results. I will update these this winter with other models buried 1.5 meters down in the snowpack. While in SEARCH for an Ortovox 3+ transceiver a signal was always acquired around on average between 30-40 meters with on result of 28 meters when the transmitting transceiver was in a poor coupling orientation. These results support Ortovox’s suggestion of a 50 meter search strip width in this open terrain with no interference. Yet another innovation feature of both the Ortovox Diract and Diract Voice is the unit somehow analyses the surrounding area for interference and adjusts the recommended Search Strip Width to be optimized. For example, in the open field (and even with my cell phone interference) the Search Strip Width was displayed as 50 meters. In my house while testing the Auto Revert function and surrounded by Wifi, electronics, etc the displayed Search Strip Width was reduced to 20 meters.
Multiple Burial Capability/Flagging (Signal Suppression)
The Ortovox Diract and Diract Voice transceivers have an intuitive system for helping the user manage the incredibly complex scenario of a multiple burial. The first is the display with indicate multiple signals with little “person” icons on the bottom of the display (up to three). This is another moment where I would have loved if the voice command could have verbally alerted me with something like “Multiple signals detected”. This addition would really help a searcher understand the bigger picture faster and manage their resources appropriately. Once you have finished your fine search and achieved a positive probe strike you can press and hold the flag button to have that signal suppressed, at which time the transceiver will direct you to the next closest burial. From my limited testing and reading of the manual there is not an option to “un-flag” a flagged victim. Should that be needed (and it shouldn’t if you use this feature with the caution taught in rescue courses) you will need to place the transceiver back into SEND then revert to SEARCH to remove all “flagged” targets. <insert info on any verbal instructions during FLAGGING>
This is a big moment in the history of avalanche transceivers. While there are a few great transceiver manufacturers out there I’m not surprised that Ortovox was the first to produce a transceiver that is so different from everything else out there. The benefits of a talking transceiver might vary by the user. Those who consider themselves “experts” in avalanche rescue will likely feel the effects of the voice commands less important as they are used to “listening” to the visual and audio clues of the various transceivers they have used over the years. In my opinion those advanced users might decide to upgrade to the Ortovox Diract (without voice) simply for the solid performance and benefit of the internal battery over transceivers that burn through alkaline batteries. Those who are new to avalanche rescue, or (gasp) rusty on their rescue skills (take an Avalanche Rescue course!), will likely find the voice commands from the Ortovox Diract Voice to be quite beneficial at guiding actions during the stressful moments of an avalanche rescue.
As mentioned this is an initial “first look” type review as I’ve only had this transceiver in my hands for about a week. I will test it throughly this winter while instructing over a dozen avalanche courses and will update my findings and opinions likely by late January. If you were planning on upgrading or buying you first avalanche transceiver this Fall in preparation of the winter I hope this information has helped you decide if the Ortovox Diract or Ortovox Diract Voice is the right transceiver for you, and if it is you can purchase one from these online retailers:
At the end of the day as an avalanche educator I’d be remiss if I didn’t end this review with the classic avalanche educator’s disclaimer.
