AXXIS TITANIUM™ is a completely new detonator system based on the successful features of AXXIS GII™, such as dual capacitors, high-strength cable, remote blasting, and safety.
The system is designed for high safety and security levels, but remains easy to use.
It requires minimal menu run activity for setting up a blast, making it easier for blast crews to apply this system with the field processes.

Functional Features
- The system utilises dual voltage with on-the-block logging and testing at a low, safe voltage.
- Detonators are programmed and tested during logging by writing the desired firing times and log sequence number (position) into each detonator memory. Centralised programming using the flexibility of computer-based design is also an option.
- Error testing is reported by exception, which considerably speeds up the centralised testing and blasting processes—with the resulting time required at the firing point being less than two minutes, regardless of the number of detonators being fired.
- Each detonator can be programmed at 1 ms intervals to a maximum of 35 seconds at a very accurate standard deviation of ±0.0025 % at a 35 second delay.
- Data transfer between boxes and loggers takes place wirelessly through Bluetooth, but with USB back-up.
