AIRMAR B75H 0DEGREE TILT

Single Channel CHIRP

Using pulsed transmissions swept across a range of frequencies, CHIRP technology delivers superior target resolution and depth penetration to traditional single-frequency sonar. This single channel CHIRP transducer operates anywhere in the 130-210 kHz High CHIRP frequency range, with a 15-9° beam width. With High CHIRP, the B75H provides an operating depth of up to 310 m (1000 ft).

Depth/Temperature

One sensor does it all. Able to measure both depth and temperature in a single package, the B75H simplifies installation and requires just one connection to your echosounder module or multifunction display.

Deadrise Compensation

The B75H's 12° fixed tilt is ideal for boats with an 8° to 15° hull deadrise. An untilted (0°) version is also available, and a 20° tilt to compensate for deadrises of 16-24°. With ceramic elements tilted inside the housing to aim the beam straight down without a fairing block, these transducers are able to deliver more accurate depth readings and best cover the area directly beneath your boat.

Mounting

With bronze housing, the B75H is suitable for thru-hull mounting in fiberglass and wood hulls. Thru-hull mounting places the transducer in the water on the outside of your boat’s hull; a hole must be drilled for installation. This typically offers the best depth measurement and fishfinding performance.// 800) {depth = 800;if (units == "f") {$("#transducerDepth").val(feet(depth));} else {$("#transducerDepth").val(depth);}}$("#transducerData tr.data").each(function() {x = $(this).find('td.coneAngle').text();x = x.substring(0,x.length-1);angle = parseFloat(x);if (units == "f") {$(this).find('td.beamwidth').text(feet(beamDiameter(depth, angle))+"ft");} else {$(this).find('td.beamwidth').text(beamDiameter(depth, angle)+"m");}});}function findOpposite(adjacent, angle) {return adjacent * (Math.tan(radians(angle/2)));}function radians(degrees) {return degrees *(pi/180);}function metres(feet) {return (feet*0.3048).toFixed(0);}function feet(metres) {return (metres*3.28084).toFixed(0);}function beamDiameter(depth, coneAngle) {return (findOpposite(depth, coneAngle)*2).toFixed(0);}getData();});// Calculate the beamwidth for this transducerB75HFrequencyCone AngleBeamwidth130 kHz9° 210 kHz15° Depth: feetmetres
