March 24, 2014

Hello, my name is Gabe and it’s time for another HawkEye Tech Tutorial! Today, I’m going to talk about our line of HawkEye Digital Depth Finders.

Let’s begin by unpacking and reviewing the contents of the packaging. In the box there should be a display, white and black bezels and face plates, display storage cover, flush mount bracket, thick dash extension, and a bag containing a manual and the warranty registration card. Your depth finder will also be packed with the transducer of your choice. If you do not have any of these items please contact support@norcrossmarine.com and we will rush one out to you!

Now, let’s discuss the transducer options available for HawkEye depth finders. The standard transducers are a transom mount and a plastic thru hull. The Transom mount is suitable for outboard, inboard/outboard, single inboard or jet-drive propelled vessels. The hull deadrise angle must be below 30° and the transom deadrise should be between 3 to 20°. The Thru Hull Transducer is suitable for outboard, inboard/outboard, single or dual inboard, or jet-drive propulsion. The hull dead rise angle must be below 20° fiberglass or metal and cannot exceed 1.25” in thickness. The hull cannot be constructed of wood. Utilizing shoot thru technology, the D10D’s transducers can also be glued inside the vessels hull.  

Because of the D10DX’s transducers integrated water temperature sensor, they cannot be glued inside the hull.If you think that the transducer that is packed with your depth finder is not suitable for your vessel, contact us and we’ll be happy to review your installation plan. We offer a transducer exchange program that allows you to swap your standard transducer for a specialized transducer suitable for just about any installation. 

This depth finder’s auto-ranging, auto-sensitivity features means that you never have to worry about adjustments. Simply turn the power on, and you’re ready to go. The Depth Sounder emits sound signals that travel through water, and then calculates the amount of time that elapsed while the signal traveled down to the bottom and returned back to the transducer. This time is calculated by the microprocessor and displayed as a depth reading. Extremely dirty water, very soft bottom, high speeds, deep water, aeration, or a combination of the above will result in incomplete or inaccurate readings. Under these conditions variable readings or three-dashes will be displayed. 

If you are not happy with the on water performance of your depth sounder, we’re here to help. Rest assured that this depth sounder is engineered to the highest standards and is part of the best selling family of depth sounders in the world. It is highly likely that your dissatisfaction is due to improper installation. Nine times out of ten, performance issues are the result of improper installation of the transducer. I cannot stress enough, the transducer must be mounted so that it has an uninterrupted supply of clean, aeration free water. If the depth finder gives accurate readings while the vessel is sitting still, but changes to “---” while the vessel is moving, is almost always a result of aeration to the transducer face. In this case you should review the transducer installation guide and adjust the transducer as suggested.
