Scientific Details of the NOGGIN® Ultra 100 GPR system

The NOGGIN® Ultra 100 system contains an Ultra Receiver that provides trace stacking up to 65,536 times. This lowers the noise floor to see deeper, real GPR reflectors up to 3 times deeper than before. It also couples our patented DynaQ technology to Ultra Receiver stacking for the first time. This webinar explains the scientific details behind these two innovations.
