Garmin Thru-hull transducers, as their name implies, are installed in a hole drilled through the hull.

Benefits of AIRMAR’s Thru-Hull:

• One broadband transducer covers up to 117 kHz of bandwidth - greater opportunities to detect fish in the water column.
• Superior resolution - precise separation between baitfish and gamefish represented on the display with crisp images.
• Enhanced bottom fishing - resolve targets close to the bottom or near structure/wrecks.
• Amazing detail - recognize haloclines and thermoclines.
• Improved signal to noise ratio - find fish and track bottom at high boat speeds.
