Transducer ???

Ok guys, I've always been a Lowrance fan myself but my dad just bought a Humminbird unit. My question is about a transducer that he bought for it.
[B]XNT 9 QB 90 T[/B]
Quadra Beam, 20/60/90 Degree, 200/83/455 kHz with built in temperature.

It claims to have a 90 degree beam. That means if your in 20' of water you would be seeing 40' of the bottom of the lake.

Does anyone have a Humminbird unit with this transducer, if so what are your thoughts on it and does it really have a 90 degree beam?

Most other brands have the 200/83 kHz, 20/60 degree transducers but this one is the first one that I have seen that claims to have 90

Thanks DJ

Hey DJ, hope I can help you out here, but seems like there's some confusion. The Quadra Beam sonar has a four-beam layout: a standard 20/60 degree, and two 35 degree shooting out laterally. This should be at or a little over 90 degrees total when the two 35's (the 455 kHz) overlap a little, and yes, would give you wide coverage twice that of your depth. However, the readout is pretty confusing, and don't care for it myself. I work at BPS and get a lot of confusion back about how it works. Avid supporter of Humminbird, but need to go back to the drawing board on this set up.
