Selecting the type of mount you want for your marine transducer can be a difficult decision. There are advantages and disadvantages to each type, and ultimately the decision rests on how much power and detail you want to get out of your device.
In this post we'll walk you through some of the features to consider when deciding between a transom-mounted transducer and one that is attached to the inside wall of the hull:
- Shoot-Through ("In-Hull") Transducers: These are mounted on the inside of your boat, typically in the bilge, which is the closest part of your boat to the water. The advantage of this type of mount is that you don't have to drill a hole in the bottom of your vessel in order to use it. Instead, it sends a sonar ping through the hull's material, which severely limits its ability to deliver in-depth information about what lies beneath your boat. The hull tends to absorb some of the ping's power, which means that you'll get a less detailed image.
- Through-Hull Transducer: Drilled into the hull of your boat, through-hull transducers give you more accuracy, as well as a more permanent transducer solution. They're typically the most expensive to install and replace, as they require you to permanently incorporate them into the structure of your boat.
- Transom-Mounted Transducers: In terms of power and accuracy, you can't beat a transducer mounted on the transom of your boat. This puts it in direct contact with the water, which means that there's nothing in front of the transmitter that absorbs the sonar waves. As a result, you'll get much more useful information out of your transducer, particularly if you're boating in deeper waters.
