No, it does not, it's just the name. We apologise if this has caused any confusion.

We're considering it! We will test engraving numbers on the face plate and do some test jumps, and possibly offer it as an option before the altimeters ship out. Unfortunately our laser cutter is having problems at the moment and we are working hard to get it back in operation.

However, the main indicator we use are the colours, and we find it really easy and intuitive - so numbers will only supplement the colour indication.

The prototype altimeters you see in the videos and photos did not have the alignment slots the final version will have, so they were not oriented properly. The production altimeters will count down counterclockwise like most altimeters, and we will release videos of them once the first production units are complete.

Green, yellow, red. Simple!

We regularly jump with this altimeter and we find it quite fun and useful! We find that the colour code is easier to interpret when a quick decision is needed - for example, it's easier to see the signal to pull (especially when in a track). We also find the canopy mode useful as it makes it easier to see small increments below 2000 feet compared to analog altimeters.

Third advantage is that this altimeter can be easily worn on your right wrist instead of your left, and it's easier to see in sunset or night jumps.

As always, please follow the safety regulations and rules set by your DZ, CI and regulatory authorities for every jump.

No. Unfortunately this feature would have added a lot of cost to the altimeter, which we are selling for just £110 (£99 with a discount). If we added these features it would double the price of the altimeter!

The 4000ft "pull" red colour is in line with the BPA regulations for minimum opening altitude, which is described in Section 8-4 of the Operations Manual (June 2013 amendment) which requires a minimum opening height of 3000ft for parachutists below 'C' license, taking into account that most canopies take at least 500ft to open.

However, we may look at adding adjustable altitude colours in a future version, and we have more advanced altimeters in the pipeline!

The altimeter zeros itself the moment it is switched on. To re-zero it, simply switch it off, then switch it on again.

When the altimeter is in canopy mode, the ground will be much, much closer. We highly recommend that you keep an eye on how close the ground is.

We are working on an indication from a central LED to indicate the transition from freefall mode to canopy mode, and we'll post updates here as we progress with this feature.

In designing this altimeter we've assumed some familiarity with formation jumps and canopy landing patterns so we don't recommend this altimeter to students, and advise against high-performance landings until you are very familiar with the altimeter.

We do not recommend this altimeter for everyone - we've aimed it mainly at FS jumpers. Altimeters, whatever type, can only supplement a jumper's awareness and safe behaviour! Please check with your CI or Safety & Training Adviser before jumping any new equipment.

What you will get is a production-standard altimeter (version 3).

The prototype shown in the photos and videos (version 2) have some features missing:
- battery level needs a separate device to plug into the altimeter
- the prototype is counting down clockwise not anticlockwise (due to the circuit of the LEDs)
- the prototype does not have alignment slots so 12 o'clock position is not consistent
- the prototype does not have a USB charger
- the prototype does not have a central LED indicator for transition between canopy and freefall mode

The production version will fix all these issues, but the laser-cut case will look the same.
