DFF3D TM54 transducer doesn't read at speed on TZTXL 13

[Nannyslayer]

Hi Guys,

I'm not getting any bottom reading above 7 knots from my Airmar TM54 multibeam transducer which is linked to a Furuno TZTXL 13.

I have installed an aftermarket custom bracket which makes it more adjustable and brings the transducer face way closer to the transom to try find clean water. But still no improvement.

It's installed between strakes and I can't see anything else that would disturb the water flow.

Does anybody have a TM54 multibeam working at Cruise speed?

Thanks
