"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
"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 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. "

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
"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
"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
"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. "
