Set ", it is inconvenient using hawser bring that self-returning hydrophore is avoided, while there is also shortcomings, the i.e. release of counterweight
It is not recyclable that sampling cost is caused to greatly increase, while the waste of resource is caused, or even the destruction to underwater environment.Although not making
Other articles in plant roots and stems and water body are avoided with hawser to impede hawser, but plant roots and stems once occur to adopting
Hydrophone itself impede and the case where hydrophore breaks down, and counterweight cannot discharge, will lead to hydrophore can not emersion water
Very big loss is caused in face.And be not suitable for using in the biggish environment of flow rate of water flow, hydrophore is carried out after adopting water
It finds, can all increase and adopt water workload.
