Fcv-295 with airmar R509LH

[Fishkraze]

I am currently running a fcv-295 with an airmar R509LH on a 28ft lobster boat. I mostly deep drop fish anywhere from 90-200 fathoms of water in the Caribbean. I can’t seem to pick up any fish on or near the bottom. I am wondering what setting I need to adjust to be able to pick up fish. The unit is currently running in auto. I am hoping someone can help me out.
Thanks

Fishkraze,

You can use the R509LH's 200kHz down to 100 fathoms (600 ft), for shallow water fishing and for over structures and wrecks. However, if you need to go deeper then might consider changing the FCV295's high side frequency to 155kHz with a Bandwidth set for "30kHz". Keep in mind that the FCV295 has specific frequencies that are locked out due to internal inverter noise: 54-64kHz, 111-139kHz, and 171-183kHz. So, using 155kHz is a good place to start if you want to go deeper using the high frequency side.

For the low side frequency, I'd go with 32-35kHz with a band width of "20 kHz", the R509LH really likes those low frequencies. Also, make sure that your FCV295's TX Power is set to "10", and not for AUTO.
