🎣 Airmar TM165HW – A Budget Snapper Sounding Weapon for Port Phillip Bay

📡 Airmar TM165HW Transducer – Perfect for Port Phillip Bay Snapper

If you fish inshore for snapper in Port Phillip Bay, you’ve probably looked at the high-end Airmar 175HW and wondered — do you really need to spend nearly $2,000 just to mark fish in 20 metres of water?

Good news: You don’t.

The Airmar TM165HW is a 600W transducer with a 30° beam angle, making it ideal for shallow water. It runs high chirp (150–250kHz), giving excellent coverage under the boat — in fact, for bay work, it arguably performs better than the 175HW thanks to its wide horizontal footprint.

✅ Why the TM165HW Is Perfect for Port Phillip Bay

  • Wide 30° beam – covers more water, helps you spot snapper arches
  • 600W power – plenty for depths up to 24m
  • High chirp frequency – gives excellent clarity and separation
  • More affordable – perfect if you’re not heading offshore
The 175HW is fantastic — but unless you’re deep dropping, the TM165HW makes more sense for bay fishos chasing snapper.

🎬 Real Snapper Sounding & Results

We’ve been using the TM165HW in Port Phillip Bay, and the results speak for themselves:

  • Snapper caught within 5 minutes after anchoring on marked arches
  • Double hook-ups right after sounding fish
  • Clear arches on Lowrance HDS Live displays

💡 TM165HW Beam Width at Different Depths

Depth (m) Cone Width (m)
7 4
15 8
18 10
20 10
24 12

Pro Tip: In water shallower than 8m, switch to 83kHz for a wider 45° beam — perfect for scanning flats. But for most bay fishing, high chirp gives better target clarity.
