Fathom-E tether interface

Hi I have ordered a Blue Rov2 and a Fathom-E teather interface. Teather is 100m. Is this ok or do I need the Fathom-X It is for the topside computer

Hi @Bovikarby, the BlueROV2 includes a Fathom X for the topside computer. A Fathom X topside will be necessary. Do you know if your order is shipped? Contact support@bluerobotics.com and we may be able to remove the other item from your order if you do not want it.
