XDeep Black Bottom Timer


xDeep has stopped the production of Bottom Timer.

Great contrast and perfectly legible.
No matter what depth.


XDeep has started the European distribution of its revolutionary new (and upgradeable) OLED Black Bottom Timer with amazing features at a surprisingly affordable price.

Equipped with a high resolution, full colour, OLED display with amazing readability in any conditions, the bottom timer is future-proof with upgrade-ability to become a full-blown Nitrox or Trimix computer.

The BT is packed with unique features including digital compass with 'Guide me' function, switchable screens and different colour schemes, logbook, computer download and many many more! Extremely durable housing with bungee mount built in.


Despite using a battery with a large capacity and a legible OLED display, the BLACK BT remains outstandingly compact. In addition it resists depths up to 200 m!

All due to its extremely durable, CNC machined housing made of single polyacetal (POM) block.


The BLACK BT is incredibly tough. Every piece is tested during the production process under the pressure corresponding to depths of 200m.

VSI. Buoyancy under total control 

The unique Vertical Speed Indicator visualizes clearly the speed when ascending and descending, allowing you to control your buoyancy in a very precise way. 

When diving in water column without any reference points, you will be immediately notified by VSI whenever you start to descend or ascend, which will make it easier for you to maintain the planned depth. 

But that’s not all! You can set various ascent speeds for various depth ranges – for example slowing down your ascent rate as you get shallower and shallower, thereby decreasing the DCS risk.

Compass. Precise and advanced.

BThe BLACK BT also includes an advanced, three-axis compass, as precise as classic magnetic compasses.

However, the BLACK BT can do much more than any other compass! 

First of all, you can keep your set course really easily, because the compass will notify you every time you sidetrack. Secondly, with advanced navigation functions such as the ‘return’ function or waypoint navigation, you will always get to your desired destination…. and back again!

Alarms that you will never miss.

The BLACK BT is equipped with five different alarms, which you can set at any time, even during diving. 

When you exceed the set alarm value, the BLACK BT will notify you about it, first by flashing a bright red, and then displaying the alarm on the main screen. 

And if you want, you can mute the displayed alarm at any time so as not to cause a distraction.
Logbook, which stores all information.

Thanks to its powerful processor and large memory, the BLACK BT is equipped with a very detailed logbook. Not only can it log depth with a 1 s frequency, but also store many hours of diving.
This is not the end though! The BLACK BT records all the most important events: exceeded ascent rates, temperature diagram and a lot of other useful information. You can browse through all of this with just a few clicks.
