Device FAQs


Where should I store my Dekunu device?

Store in a cool (preferable below 30°C), well ventilated area, away from moisture, sources of heat, open flames, food and liquids

How long does it take to fully charge my device?

For a full charge from empty, it should take approx. 3 hours depending on the power source and providing you are using the Dekunu supplied data cable

How long will the battery last for?

In real world usage, at least a full weekend of jumping, we will do further development to extend this with future software updates

Does the device charge while switched off?

Yes. If you have firmware version 4.1.2 or higher the device will charge while switched off

How do I know if the device is charging?

If switched on, the LED on the device will slowly flash green while charging, once it has reached capacity, the LED will remain a steady blue while connected to a power source. There is no visible indication that the device is charging while switched off

I am buying/selling a Dekunu One, how do I register the device into a new users name?

First a Cloud Portal profile will need to be created for the new user - if not already done so, sign up  here

Once the profile has been created, simply follow these instructions to switch users

Device Activation & Login

What is my 'User I.D and Auth Code?'

On receiving your device, your user I.D will be pre-populated in the 'Log In' screen, if your user I.D does not show, log into the Dekunu Cloud and go to 'My Profile'.  Your I.D is located under your name, on the left hand side of the screen.

Your Auth Code can be found in your Dekunu Cloud profile settings in the Privacy & Security tab

If you have not logged into the cloud before, follow these instructions to reset your password

If you do not have a Cloud profile, follow these instructions to set one up


Does the One automatically select the dropzone based on your location? 

If you have Wifi and GPS connection, the One will let you know if your current location is far away from your selected dropzone and ask if you would like to change to a closer DZ. We decided to not make it automatic because of inhopps. Developers are working on some new functionality within the Dekunu Cloud so that an analysis can be performed to override any incorrect location settings, this will be rolled out at some point in the near future.

If I go to a new DZ that I have not added to my profile, how will it show up in a log?

Your device contains a selection of nearby dropzones based on the last refresh when connected to the WiFi and GPS. If you don't have the current dropzone on your device and are unable to connect to WiFi, then the device will not know which DZ you are at. When you next connect to Wifi, try changing the DZ on your device before the logs sync. If you are unable to do so and the logs sync under a different DZ, don't worry, you can  modify the DZ yourself on your Cloud Profile or mark the log for review and someone from our tech team will fix it up for you.

Does the device adjust your ground altitude automatically for each different DZ?

The device will be aware of the change but it will require some user input, an Altitude Offset feature will be released in the next firmware update.

Wifi & GPS

Will the device offer the same features as other GPS mapping devices on the market?

Yes, the device will track a huge amount of data including all that other GPS mapping devices track plus heaps more.

How is data synced?

Data is synced to the Cloud via Wifi, this will automatically happen when the device has a connection.

Can you connect the Dekunu to a mobile hotspot and sync up using the data connection on your phone?

Yes, you can. Simply follow the instructions in Connecting to Wifi and select your personal hotspot as the network. Please note, as a general rule mobile phone hotspots are not known for being the strongest connections. If the syncing of your device is running slow, this is most likely the reason.

Will the device have direction arrows and distance to DZ shown on both wingsuit and canopy flight screens?

We built the direction arrow and distance functionality on an earlier prototype but decided to remove it for certain safety and legal implications. There were several risks involved with having a canopy pilot spending too much time looking at their device instead of around the sky. This feature is still on the backlog and will be implemented when the time is right.

Does the device have captive portal (with password entry) capabilities?

Not at this stage but it may be implemented in one of the future updates.

How many concurrent satellite connects will the device attach to?

The integrated GPS feature allows the device, depending on the time of day, local obstructions, interference and location in the world, to connect to anywhere from 5 to 15 satellites.


Does the device have audible alarms?

Not currently, however, software updates will be sent to users with new features as they are developed. 

Will I be able to change the language on the device?

Current orders are shipped out with English as a language. We will be sending out software updates with other languages in the future.

Do we have to connect our devices prior to jumping in order to log who is in my group?

No, differentiation is made by exit time and proximity during freefall.

Will the device include games?

Games are in development, they will be included in a software update in the future.

Software & Capabilities

Will there be a service fee for updates etc.?

No, there will be no extra fees or hidden costs.

How/when do I update my device?

Your device will notify you when it is connected to Wifi and there is a new update available. Follow these instructions to update your device.

Will the device be compatible with Android and/or iOS?

Initially we are launching with the web portal, soon it will be optimised for mobile platforms. We are already developing companion apps for iOS and Android.

Are you using a custom OS or is this built on top of something like AOSP?

We are using our own custom OS.

Will I be able to migrate data from Jumplog/Paralog etc.?

The device has an open API, which will enable developers to migrate existing data from other sources into the cloud associated with your Dekunu account.

Does the device interfere in any way with US FAA regulations regarding interference?

No it doesn't, any interfering signals are disabled throughout flight.

Do I need to have a Dekunu profile?

Yes. Your device will not activate without a profile. See how to  Set up your Cloud Profile and How to Login.

Mounts & Hardware

How do I know what size wrist mount to buy?

Please note, the wrist mounts are a smaller fit than other leading altimeter suppliers. If you are unsure of your size, contact us or if you know someone who owns a device ask to try on their wrist mount to measure. 

The inside circumference of the wrist band when it is slack is:

      Small – 14 cm

      Medium – 16 cm

      Large – 18 cm

      XL – 20 cm

      2XL – 22 cm

A slight to medium stretch will enlarge the circumferences by about 2cm. A stretch of no more than 2-3cm is recommended for a comfortable fit.

Is there a Wingsuit mount available for the device?

Yes, a Dekunu Wingsuit Mudflap mount is available for purchase  here. You can also download this guide How to Attach the Dekunu Wingsuit Mount 

What IP certification does the One have for water resistance/water proofing?

The testing for IP rating has not yet been finalised. We will advertise this once formally identified. Until then the only waterproofing we are permitted to communicate is "water resistant".

Testing & Development

How many test jumps have you done?

Throughout the prototyping phase we've logged over 6000 test jumps and will continue to test jump as new features are added to the platform.

Has the device been tested for HALO jumps?

Yes, the device has been successfully tested for HALO jumps.

I would like to offer some suggestions on new features or improvements, how do I go about that?

Fantastic!  We welcome any and all feature suggestions, please head over to the Dekunu Community page for more information on how you can have your say and to discuss topics with other Dekunu users.
