Garmin 1kW Transducers Australia – Offshore CHIRP Performance

If you’re fishing serious depth or running wide offshore, a 1kW transducer makes a massive difference. Garmin 1kW CHIRP transducers deliver stronger bottom lock, better target separation and cleaner returns in deeper water compared to lower powered setups.

At Shotgun Marine, we supply Garmin 1kW transducers Australia-wide and provide professional installation from our Port Macquarie NSW workshop.&;

What Is a 1kW Transducer?

A 1kW transducer transmits more power into the water, allowing your Garmin sounder to maintain bottom tracking at greater depths and cruising speeds. It’s ideal for offshore reef fishing, deep structure work and serious bottom species.

Garmin 1kW Models We Supply

• Garmin TM185M (Medium CHIRP)
• Garmin TM275LHW (Low High Wide CHIRP)

These models pair perfectly with high-end Garmin GPSMAP systems such as the Garmin GPSMAP 8416xsv.

1kW vs 600W – What’s the Difference?

A 600W setup can perform well in moderate depths. But once you push into deeper water or want stronger target separation, 1kW provides:

• Stronger bottom lock in 100m+
• Improved fish separation
• Cleaner returns in offshore conditions
• Better performance at cruising speed
• For serious offshore fishos, 1kW is often the smarter long-term investment.

Why Installation Matters Offshore

Even the best 1kW transducer won’t perform if 

mounted in turbulent water. Correct deadrise matching, hull placement and proper sealing are critical.Our marine electronics installation NSW service ensures your Garmin system performs properly when you’re wide of the bar.

Customer Feedback

"Upgraded from 600W to a Garmin 1kW setup and the difference offshore is obvious. Holds bottom deeper and the fish separation on reef is much cleaner. Install was done properly for my hull and it shows." - Matt S, Neslon Bay Fishing Club NSW
