Airmar B258 Bronze Thru-Hull Depth/Temperature Transducer

The B258 is an excellent, economical, 1 kW, dual-frequency transducer for anglers. Its unique four ceramic-element construction produces an elliptical beam that covers a wider area and produces excellent target resolution. The combination of 50 and 200 kHz make it a great option for both shallow and deep-water use. The included High-performance Fairing gives excellent results at speeds up to 30 knots (34 MPH).

Features:

• Depth and fast-response water-temperature sensing
• 1 kW of power
• Dual-frequency elements producing elliptical patterns for wider coverage
  • 50 kHz with a 15 x 21 deg. beamwidth for depth performance to 2200' (647 m)
  • 200 kHz with a 3 x 5 deg. beamwidth for depth performance to 1000' (294 m)
• Bronze-housing with high-performance fairing for optimal performance at speed
• Greater surface area resulting in better sensitivity
• Patented Xducer ID® technology
