DFF3 capabilities in ocean cruising?

[A4A91120]

On our recently purchased blue water solid hull 42' custom rigged for circumnavigation cutter, we are planning our dry dock, perform thru hull replacements, and install a DEEP water depth sounder. We are going with TimeZero 4 and we having to use the DFF3 that claims it supports depths of 10000' when properly installed. We may even resort to standalone Furuno models that work with TimeZero. All I see is claims, what are the designed limits in data types and testing of the 3kW+ transducters? There are no technical reviews other than some opinions and sales jargon on the limits of low frequency transducers. Other manufacturers have screenshots of 28Hz showing 11123 feet on their MFD's. So for the price of quality and reputability can Furuno publish results? Likewise I would like to know if the DFF3 can accommodate a high frequency 200Hz transducer while handling the low frequency power of CA50F-38 and a half version of the BT-5. This maybe the wrong direction. Are there any deep sea people here that would recommend a preferred and proven combination of transducers for the purpose of recreational ocean cruising? :sail

A4A91120,
I don't have any supporting documentation on the DFF3 at that depth. The deepest screen shot I have is of a FCV-1150 using a Airmar 599LM is 1500fm (left side of display). It was from a factory trawler that was headed up to Alaska. They were trying difference frequencies just to see what they could see. The interference is from the three other sounders they have onboard. Remember frequency is more important than power when looking deep, so 28Khz will go deeper than 50Khz.

Snips, thank you so much. This is exactly what i was looking for. Wow, 16.5 knots! Best wishes. Marcus.
