I have a helix 10 G2N with mega transducer; looking for recommendations for best placement of transducer. I'm losing depth readings and picking up turbulence at low 8mph with traditional sonar and chart displayed. The boat is a 2015 G3.


Here is photo of current installation. Thanks in advance for your willingness to help.

Most sonar fall off at 5 mph. If you are still getting correct info at 5 mph, everything is correct.

Hey Ben, on my G3 Angler, if I drop my transducer where you have yours I get a rooster tail spray on my engine cowling but I get depth readings up to 45-49mph. When I raise the transducer up a 1/8" the rooster tail is gone but so is my depth reading over 8mph. I to have the poly plate where I can make adjustments to the transducer. I would recommend you experiment with moving the transducer around.
Being we have an aluminum boat and the traditional in-hull transducer will not work, I simply have my electronics on full view chart and watch the depth contour to keep me safe when traveling across the water at high speeds.
I have been looking at the following (link) transducer but am skeptical... http://www.radarsonics.com/AlumaDucer.htm I may order one and try it on my boat as an alternative for our aluminum boat customers wanting an in-hull transducer if it is proven to be worthy.

The Alumaducer works great if installed properly in a hull that is not too thick and/or has a bottom that is smooth with no dents or rivets forward of it. Check the specs.

Thanks very much! I will install a 2D transducer on the left side of the transcam and see what happens.

Installed the 2D High speed transducer; still losing depth. Any reviews on the alumaducer? I sent an email to G3 customer service and got very little support from their technician manager. I'm sure that the design of the bottom of my boat is what is causing the problem.
