Pro tip: Kiss Helmets

So you want to buy Brilliant Pebbles, but our Kiss Helmet Adapter is out of stock? In this post we discuss some alternative options you can take to make the audible work with your helmet.

Continuous Improvement

So you've bought a Brilliant Pebble, you enjoy jumping with it, end of story?

Not at all. We've released Brilliant Pebbles with the bare minimum of features to make absolutely sure we can deliver on our promises. However, the hardware is actually capable of quite a bit more - the pressure sensor in Brilliant Pebbles is actually 2 generations ahead of most competitor altimeters!

So we have built in to Brilliant Pebbles and its software the ability to update over the internet. First, some terminology to clarify:

Prepare for launch!

After lots of hard work, Brilliant Pebbles is almost ready for launch!

We've been very busy producing Brilliant Pebbles, sorting out the packaging, software and user manuals. This is in addition to lots of testing and checking to ensure you receive a polished, tested product right from launch.

Many of you have been asking for an exact date, unfortunately we can't commit to one just yet - our suppliers are hard at work producing essential components of Brilliant Pebbles, but shipping and other delays might get in the way. One thing we know is that we're very, very close!


After a 7-month test campaign, Tritium has passed its final round of tests with flying colours! (See what we did there?)

The last round of testing was particularly gruelling - we had to ensure that it didn't radiate any emissions that could potentially affect aircraft systems, blast Tritium with high-powered radio waves and fire 8,000 volts into it to simulate electrostatic discharge. We chose the test levels to be above and beyond any conditions we expect altimeters to actually encounter, and we're very happy to say that Tritium passed all the tests!

Almost there!

So what have we been doing these past few months? Since we assembled our first few production-standard altimeters, we needed to test several important parameters that were not present in the prototypes.

We needed to test several parameters and validate:

Night Jumps

Finally, on 1st February 2015, the weather cleared enough for us to do a night jump!

We've been attempting to do a night jump since last year, where they are normally done in the autumn or winter when the days are short. However, the fickle weather of the UK has caused the THREE previous scheduled night jumps to be cancelled, which was extremely frustrating.


Understandably, skydivers are concerned about the reliability of their altimeters. So how does Tritium achieve reliability and accuracy?

Analog altimeters typically use a sealed chamber, which expands or contracts depending on the air pressure. This drives a spring, which then turns the needle of the altimeter. Well-designed metal springs can have lifetimes of several thousand cycles, and analog altimeter failures are quite rare (but they have been known to happen).

Skydive the Expo

We've just come back from Skydive the Expo, and it's been an amazing experience!

Although we were not selling the Tritium altimeter during the AGM, we were spreading the word about it as well as carefully listening to feedback people had! We know that Tritium may not be suitable for all kinds of jumping, but we will carefully consider all the comments made during the AGM. If you were there, we also showed some very early and exciting prototypes of our future products as an answer to some of the features lacking in Tritium!


Did you know, that if you took out all your blood vessels and laid them end-to-end, would probably die? Because really, that's something you shouldn't be doing.

Luckily, this isn't the case with an altimeter! We can lay out the electrical circuit without affecting the operation of the altimeter into a prototyping board, as you can see in the photo above.

Believe it or not, the prototype above is actually testing a number of things:
