🌊 Step 2: Ultrasonic Waves Keep Your Hull Clean
High-frequency sound waves prevent algae, barnacles, and biofouling from attaching—without chemicals or maintenance.
💰 Step 3: Save Thousands on Cleaning & Fuel Costs
With a vessel free of fouling, you burn less fuel, maintain top speed, and avoid costly haul-outs and diver cleanings.

Thanks to Echo Tech our boat is clean year round.
"South Florida waters are brutal when it comes to growth and our Pardo E60 was no exception. Our maintenance costs were getting annoying so we looked into Ultrasonic Antifouling. We chose Echo Tech because their team was extremely helpful. Now we can spend more time on the water and less on maintenance. Thanks to Echo Tech our boat is clean year round. "
— Mike S. - Pardo E60 in South Florida
After installing Echo Tech we no longer needed a diver
"We were talking with some friends about maintenance on our boats and they mentioned ultrasonic. I had heard of it, but that was it. We were diving regularly and conducting annual bottom jobs on our Valhalla 41. After installing Echo Tech we no longer needed a diver and annual bottom jobs have become a thing in the past. "

It’s been months since we’ve had a diver
"It’s been months since we’ve had a diver and our Pardo 43 is as clean as the day it went in the water. Echo Tech Ultrasonic Antifouling works amazing and we struggled to believe it before we installed it on our own boat. Now we’ll never own another boat without it. "

You’re Still Here… So You’re Interested. Let’s Talk Real Savings
We get it—ultrasonic antifouling sounds almost too good to be true. But you’re still reading, which means you’re curious.
💸 The Real Cost of Fouling: A 42’ Sportfish Example
Let’s say you own a 42’ sportfish, kept in warm coastal waters. Here’s what you’re spending to keep it clean:
Diver Cleanings: $250 per visit (once a month) = $3,000 per year
Haul-Out & Bottom Scrape $3500 every 12 months = $3,500 per year
Extra Fuel Costs from Drag: +10% increase at $5/gal = $2,000 per year
Bottom Paint & Reapplications: $6,000 every 3 years = $2,000 per year
And no matter how much you spend, barnacles and algae still come back.
I recommend Echo Tech to every boater
"I was spending thousands a year on diver cleanings. Since installing ultrasonic antifouling, my hull stays clean, and I haven't needed a diver in 18 months! I recommend Echo Tech to every boater"
— Jeff Jacobs, 328 Pursuit Charleston, SC
Couldn’t be happier. No more diver
"Before using ultrasonic, we had a diver a couple times per month and our annual haul-out required a bottom job annually. We installed Echo Tech Ultrasonic Antifouling over 15 months ago and couldn’t be happier. No more diver. No annual bottom job and our Viking 55 is nearly spotless.
"
— Jeff S. - Viking 55 in New Jersey
No More Divers—Pays for Itself in a Year!
"Our Valhalla V-33 constantly needed diving and cleaned. Bottom jobs were getting annoying and expensive. We chose Echo Tech Ultrasonic Antifouling to protect the hull using a PRO-4 System. The results were better than expected and we’ve eliminated regular diving completely and deferred our annual bottom job another year! I’d highly recommend Echo Tech for Ultrasonic Antifouling. "
