TNC Oceanographic has designed and produced a low-cost, robust wave gage that allows us to deliver nearshore wave data at an unprecedented value.  The low-cost nature of our wave gage also allows us to offer several levels of redundancy to ensure you get your data.  On the left is a three month comparison plot of a TNC wave gage versus a Nortek Aquadopp Profiler.


On the left is a short video of a typical wave gage swap at one of the 10ft sites from the Brevard County Wave Data Collection Project.  Due to the design of the mounting system wave
gage swaps can be performed very rapidly once on site.
  Below is  a short up close video of a wave gage in its protective holder.
