Seit ein paar Tagen ist das BRIC4 Survey Tool verfügbar. Die technischen Daten sehen schon mal viel versprechend aus. Die ersten Android-Apps unterstützen es auch schon. Leider ist das Gerät gleich mal doppelt so teuer wie ein DistoX.
Specifications:
- High precision and accuracy
- Azimuth: <0.10° precision, <0.20° accuracy
 - Inclination: <0.08° precision, <0.15° accuracy
 - Distance: 1 mm precision, 3mm accuracy
 
 - Redundant accelerometers and magnetometers to detect calibration drift, malfunctions, and magnetic gradients that could affect measurement accuracy.
- 2x Murata SCA3300-D01 MEMS industrial accelerometers
 - 2x PNI RM3100 magneto-inductive magnetometers
 - Advanced error-detection prevents bad measurements.
 
 - Egismos LDK-M2 Laser Rangefinder, 100m (328 ft) range
 - Waterproof and shockproof ruggedized construction.
- IP-67 rating, conformal-coated PCBs, waterproof buttons
 - Rubber mounted sensor assembly.
 - Screen protector on case window.
 
 - Bluetooth LE for instrument control and measurement transfer
- Compatible with TopoDroid, CaveSurvey, and soon SexyTopo
 - Note: Requires Bluetooth Low Energy capable hardware on client, Bluetooth 4.0 or greater.
 
 - Easy, quick, and robust integrated calibration on device; no external hardware required.
- 15 minutes for full calibration.
 - 3 minutes for quick azimuth calibration
 - Calibration report auto-generation
 
 - 1800 mAH lithium-polymer non-magnetic battery
- USB mini charging
 - Estimated 100 hours of normal use (100 shots/hour)
 
 - Intuitive user-friendly interface:
- Large 128×64 backlit display.
 - Displays last 5 shots, battery level, temperature, time, and Bluetooth status
 - 1 external button for regular operation, Left/Right-handed accessible.
 - 4 internal soft-keys for settings, calibration, and other functions.
 - Piezo-buzzer for audio feedback.
 
 - 8GB industrial SD card for measurement storage and calibration reports, accessible through USB.
