Product Overview

Airmar SS175C-20-MThru Hull

20 Deg Tilt Medium CHIRP with Garmin 8-Pin

Model: SS175C-20-M
  • Depth and water-temperature sensor
  • 1 kW with a maximum depth of 457 m (1500')
  • Medium Frequency: 85 kHz to 135 kHz 16° to 11° beamwidth
  • 50 kHz of total bandwidth from one transducer
  • Medium frequency provides excellent shallow to mid-depth performance, bottom detail and fish target separation
  • Recommended boat size: Up to 11 m (36')
  • Stainless steel housing is compatible with all hull types and materials
  • Also available in a bronze housing (B175M)
  • Exclusive Xducer ID® technology

Medium frequency delivers the right combination between coverage under the boat, extended depth range and the ability to produce clean and accurate target and structure returns in the mid to deeper water depths. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths (up to 1500') and delivers ultra-clear target resolution.

Because the transducer is installed almost flush to the hull, when the transducer is installed the tilt corrects for the hull deadrise and orients the ceramic element horizontally to assure maximum echo returns to the transducer.

Expert Overview

The Airmar SS175C-20-M is a thru-hull transducer designed for marine applications, providing depth and water-temperature sensing capabilities. Operating at 1 kW, it features a medium CHIRP frequency range of 85 kHz to 135 kHz, offering 50 kHz of total bandwidth. This frequency band is suitable for achieving a balance between coverage under the boat, extended depth range up to 457 m (1500'), and detailed target separation in shallow to mid-depths. The transducer incorporates a 20-degree tilt, which corrects for hull deadrise between 16 and 24 degrees, ensuring the ceramic element is oriented horizontally for optimal echo returns. Housed in stainless steel, the SS175C-20-M is compatible with all hull types and materials. It includes a Garmin 8-pin connector and Airmar's Xducer ID� technology. This unit, part number SS175C-20-M-8G, is recommended for boats up to 11 m (36') and is intended for IT or marine professionals requiring reliable underwater data acquisition.
