Plotter and sounder combined unit

Hi all,
On my previous boat ( Quicksilver 530 Pilot house)
I had a Raymarine Dragonfly 5.
I noticed once the boat was on the plane, i would lose depth and sounder, it only came back when i slowed down. I notice from a search on here that other people have had this issue.

I have just bought a 4.8M RIBCRAFT and need to fit electronics.

I was thinking, is there a similar priced combined unit to the Dragonfly, people would recommend. Bearing in mind that the unit has basic navionics card and transducer included in the price.

Going to fit a DSC Radio with built in GPS, so no worries about linking VHF to GPS. Any suggestions and where to buy from would be great,
Although i am in Ireland, i have family in UK, so they could take delivery of any UK sourced items.
Thanks in advance.
Tim B

I would suggest it's more to do with the transducer & where/how it's mounted.

Had a quicksilver 500 pilot house had no issues you will get depth at speed but no bottom return usually best 3-6 mph

If you liked the Raymarine unit Sands marine at Oxford island were selling the Dragonfly 7 at reasonable money recently.

We always had issues with Raymarine on our rescue boats at speed, funny thing was when we replaced with simrad we never had any problems even though the external transducer was placed in the same spot.

Personaly I've used Lowrance units for around 15 years, which I replace about every 3 years. I've only ever had one hull that I couldn't maintain good bottom soundings at speed with which was due to hull design, a slotted hull to add airation and lift. I tried external mounts, internal, and even cut a bronze 164 through the bottom of the boat ahead of the slot, in the end sold the boat after three months as showing bottom at crusise speed is important to me.

I'm able to clearly show bottom at speeds of 22knots in depths of 200m + and 700m when slowed right down from a standard Lowrance 200/50khz external transducer ( just like I've been able to on all my boats ).

I believe all the units are very competitive in price and function, I'm also sure the Raymarine units should perform the same, we only replaced the rescue boats units because that's how those above us operate ( replace rather than find the issue).

What I must say is I've found hummingbird units a pain to figure out with the menu's, infact my daughter's boyfriend is sponsored by them and also finds operating them difficult. In saying that the units I dabbled with were all 4-5years old, they may be more intuitive now, they certainly produce good clean images.

What sort of condition is the trailer in - might be worth dumping the trailer in the local market and pilot it back across the channel - buy a new trailer in the UK?
