At Shotgun Marine Services (SMS) and PMMS, we don’t just sell sounders - we design, install and fine-tune complete sonar systems to suit how you fish and how your boat actually performs on the water.
We’re authorised service dealers and accredited installers for all major brands including Garmin, Furuno, Simrad, B&G and Coursemaster. We’re not just an online store — we’re qualified, experienced marine electricians who assess, diagnose and install sonar systems properly, from transducer selection through to on-water performance.
From inshore fishing and offshore game boats through to commercial, charter and survey vessels, we deliver consultation-led sounder and sonar solutions across Port Macquarie, the Mid North Coast NSW and throughout New South Wales, with Australia-wide consultations available.
Garmin sounders, including traditional CHIRP, ClearVü, SideVü and LiveScope, are extremely popular with Aussie anglers. That said, as authorised dealers for all major brands, we’ll always recommend the sonar technology and transducer setup that suits your boat, hull and style of fishing - not a one-size-fits-all option.
All sounder systems are professionally installed, calibrated and tested, with sharp package pricing available for full supply-and-install marine electronics solutions focused on clarity, reliability and long-term performance.
Book a Sounder & Sonar Technical Consultation
What type of sounder is best for fishing?
It depends on where and how you fish. We assess your boat, hull type and fishing style before recommending CHIRP, side scan, live sonar or a combination setup.
Is transducer selection really that important?
Absolutely. The transducer and how it’s installed has a massive impact on performance. We get this right from the start.
Are Garmin LiveScope systems worth it?
For many anglers, yes. LiveScope is a powerful tool when installed and tuned correctly, but it’s not suited to every boat or fishing style.
Do you install sounders on commercial vessels?
Yes. We specialise in professional sonar installations for commercial, charter, survey and working boats.
