Netwave PT9 NINETY Underwater Locating Device

It was the first – and is now the first choice 90-day ULD (Underwater Locating Device). PT9 NINETY meets the requirements of IMO* and is a direct replacement for existing ULDs, as certified by BSH.

Features

  • Corrosion-resistance guaranteed
  • The worldwide available ULD
  • Vivamus imperdiet elit eu est bibendum, id volutpat diam tristique.
  • The PT9 NINETY power source
  • The PT9 NINETY Periphery, compatible with all
    PT9 ULDs

Acoustic Outputs on Activation

Initial Operation 106 N/m2
(1060 dyne/cm2) r.m.s. (during the pulse) pressure normalized to 1 metre range, that is, at a level of 160.5 dB vs 1 μPa at 1 metre
Immediately after 90 days continuous operation 70 N/m2 (700 dyne/cm2) r.m.s. (during the pulse) pressure normalized at 1 metre range, that is, at a level of 157 dB vs 1 μPa at 1 metre
