Important however you do it to ensure no air bubbles are trapped. I just stuck it to the hull using builders non hardeneing mastic like plasticine or blue tack and there it has stayed for 7 years Seems to show the depth just fine, although I have to admit to not catching too many fish a few though.
I used a Tupperware container with most of the bottom cut out, stuck it down with silicone, fixed the transducer to the side of container, fill with cooking oil, cut a notch in the lid for the cable. Joined 2 Jul Messages 3, I've done it with a Navman transom transducer without any problem. Go for it. How is this possible?
I am guessing that the hull thickness will disturb the Ultrasound waves or am i wrong? Tags: None. Rick E. Comment Post Cancel. Every transducer I have ever installed could be used as a shoot thru. But you have to make sure there is no bubbles or air pockets in the fiberglass. As Rick said it has to be bedded in epoxy with no voids or placed in a medium that will transmit energywaves.
One of my friends in college epoxied a piece of 4 inch pve pipe up right to the hull. Glued his transducer to the bottom and filled it with mineral oil. Then capped it leaving a spot for the cable. Boatless at this time A veteran is someone who, at one point in their life, wrote a blank check made payable to "The United States of America," for an amount of "up to and including their life. I just bought the dragonfly wifish structurescan downvision which he a transom transducer but this will mean my bringing the boat up for.
Few days if I wanted to mount it as recommended. I looked in my engine room no got an idea from the cavities on both sides, I wonder if I block one, place the transducer inside and make a well with oil or some other fluid. Here is a pic of one of the cavities with the transducer placed at the bottom.
Attached files. I had written a method for doing this, which I learned from another BOC member I forgot who had thought me that! I have done it successfully only with a thru-hull transducer which I installed in-hull.
Easy to maintain, easy to swap transducers, easy to check and adjust and the transducer is well protected from stuff that gets chucked into the bilge area! Boat DIY. You must be logged in to post a comment. Boat Angling. Search for:. Concept: The idea is to use a protective box stuck to the inside of the hull, and mount the transducer inside the box.
The inside dimension needs to hold the tranducer but not any mounts, so a standard size is probably fine. Get a waterproof cable gland to fit, an exterior plastic one is fine here, no need for a fancy marine gland.
Decide where you want to mount the transducer. On the outside of the hull there must be clean water flow with no bubbles or turbulance, and inside the hull it needs to be somewhere accessible but not in the way. You can check the best location with the test method described here.
It's time for another HawkEye Tech Tutorial! This transducer is suitable for vessels with the following hull types: High speed boats to increase the performance of the depth sounder. Trailer boats to prevent accidental damage to the transducer from trailering. Shallow draft boats to prevent accidental damage to the transducer from intentional or unintentional ground.
Inboard vessels that have a lot of running gear that creates significant acoustic noise and water turbulence. However, since boat hulls absorb acoustic energy, transmitting through the hull reduces the transducers performance.
These cored areas contain wood or structural foam which are poor sound conductors. Make sure you turn off all other sonar devices on your boat and locate the vessel at least 50 feet from the nearest vessel. Now, plug the transducer cable into the back of the depth sounder display and turn the display ON.
Once the display is turned ON, it will display the test sequence and then display three-dashes. Place the transducer close to your ear do not press up against your ear. If the transducer is properly connected it will be emitting a ticking sound similar to a wrist watch. If you do not hear this ticking sound, recheck your connections or visit our Customer Service Center for advanced troubleshooting.
You will need to set the keel offset to zero. Now hold the transducer over the side of the vessel so that it is the same distance below the water surface as it would be at the in-hull mounting location.
Note the depth that is being displayed on the Depth Sounder.
