Fish finder 50 meter under water

Intellectual 440 points

Hi All,
I need to be able to measure distance underwater between points with a distance of 50 meter . So I'm thinking something as simple as a sonar should work. One sends a ping the other one receives it and replies back. Is this approach feasible? Can anybody recommend sonars I can use?
OR
any other solution.Please suggest

Thanks,
Ashok

    Hi Arjun,

    Thanks for the reply.

    We are looking for low cost solution and how about PGA460 can we use this part ?

    Device 1 we need 8 TX Channels and one RX channel this is main module which floating on water surface.(Suggest me any low cost chip for device 1 )

    Device 2  This device under the water  1 TX channel and 1 RX channel  for this can we use PGA460 ?

      both the devices communicate with  each other.

    Suggest me any low cost solution.

    Hi Ashok,

    The PGA460 is really meant for Air coupled applications and not meant for underwater or liquid coupled applications. For underwater/Liquid applications we would need a device with higher frequency and currently that is not being supported by PGA460. Your best device for sonar applications now would be the AFE5809. 

    Thanks.
