Airmar TM258 Transom Mount Dual Frequency Transducer

Operating at 50 and 200 kHz, the TM258 features an elliptical beam from four ceramic elements. The beamwidth is narrow at both frequencies for excellent resolution in both shallow and deep water. The TM258 comes with a rugged stainless steel mounting bracket that is easy to install and has a streamlined shape. The combination of power and sensitivity has made this the high-performing transducer of choice for use with conventional fishfinders.

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)
• Transom mount for installation on outboard or inboard/outboard powered boats
• Stainless steel kick-up bracket locks in the "up" position and will not damage the transom
• SEALCAST™, seamless, urethane housing for long life in the water
• Patented Xducer ID® technology
