OKO‐3 FOR UNDERWATER MONITORING
The new development is the first underwater GPR of the OKO-3 series. The device received its unique properties due to the built-in underwater antenna AB-700M3P. Equipped with a central frequency of 700 MHz, it provides a wide range of possibilities for examining the condition of the underwater part of concrete structures. This development allows to immerse the GPR to a depth of 10 meters and sound concrete up to 2.5 meters.
