Most transom mounts can have good slow speed resultsbut that diminishes as speed increases due to the dirty water flow off the transom. The shoot throughs are great provided they are installed correctly.
In my experience both can work well.
Thru hull transducer vs transom mount. Transom Mount Transducer I like thru hull installations for a couple of reasons. First less exposed wiring. With a transom mount you will have to route the wire through the hull at some point usually high in the transom or up over the transom into a splashwell opening.
I hate drilling holes in my boat. With the B66transom mount things will start to break up as you increase speed and also lose reading when drifting rips. Just so that we are on the same page the B60 is a thru hull ducer not to be confused with a shoot thru one.
In other words you need to make a hole in the hull. Transom mount or shoot through for shallow water always. With the standard through hull if you knock the transducer out on a rock you now have a 15-2 hole in the bottom.
The shoot throughs are great provided they are installed correctly. Where I fish my depth finder is the. Additionally if you berley this can at time show up on your sounder with a transom mount.
I would expect both will give good readings. On a thru hull you need to ensure the transducer is not mounted to the dead rise of the hull and it is on a flat plane otherwise you will get incorrect readings. Access to your hull internally is important to mount.
In my experience both can work well. Poorly installed both can equally work poorly. In addition to less fouling problems though Ive never suffered them thru hulls also have the advantage of being less prone to running in disturbed water.
I once ran a transom mount tducer set into a glob of grease in the bilge. A thru-hull transducer will probably give you better performance and be less likely to have turbulence problems than a transom mounted unit particularly if you install a near-flush mounted tilted element xducer like the Airmar B60-12. You do not usually find transom mounted xducers on straight inboard boats but there are a few here that are.
A PROPERLY installed shoot-thru 2D transducer looses very little in sensitivity in a hull that is suitable for shoot-thru use. Yes a transducer can wear out. It is a combination speakermicrophone that transmits and receives sound waves.
Also changes in the hull can occur due to rough water operation causing some delamination or just the installation coming loose from the hull due to hull. I ended up fabricating a bracket which transom mounts the transducer and is faired into the bottom of the hull. The transducer is well protected and the water flow over the it is uninterrupted.
It bolts to the transom and is bonded to the bottom of the hull with urethane. Its almost a thru hull without being a thru hull. Thru-hull transducersgenerally offer the best performance.
This is simple anytime the transducers acoustic window is in the water the transducer will performance better. In-hull transducers cannot and do not perform as well as thru-hull or transom mounted transducers. But ultimately it doesnt matter.
Hi Jeff I just purchased a new chartplotter and have to install a new transducer. Should I go with a thru-hull on an in-hull. Also Should I have two tra.
And then mount all the transducers on that. This way you can put as many transducers as you want and only have 2 holes in the hull itself and you can also change them very easily. They way technology is in 5 years you will want the new fishfinder anyway.
Plus transom mounted transducer are alot cheaper then bronze thru hull transducers. Post by Big Block Power Thu Dec 03 2020 603 pm Lockey14s wrote. Thu Dec 03 2020 156 pm listen to you marine electronics expert friend.
A thru hull hole thru bottom is the best and most sensitive. Problems with high speed turbulence are rare to nonexistent. Transom mounts and problematic and typically have issue high speed turbulence issues 3.
Shoot thru is the least sensitive of all the configurations. A thru hull will have the advantage of running in cleaner waterso you can have better sonar capability while speed increases. Most transom mounts can have good slow speed resultsbut that diminishes as speed increases due to the dirty water flow off the transom.
Tyou wont look back i had mine in hull 600 watt untill i bought the through hull 1kw. Worked a treat and a good speeds. I was told by a transducer salesman to fill a bag full of water put the transducer into it then move it around you hull till you find the best spot for it just be carefull to make sure there is no air between the bag and the hull.
Do this at rest then when moving. This is if you have room to move your transducer. Post by Mike in SC Sat Mar 27 2021 1225 pm I would like to know how this ended up and what Cobalt does with factory installation of the transducers.
An example is the splitshot transducer from Lowrance is a transom mount unit but manufacturer says its OK to epoxy in-hullLowrance also makes a Pod shoot-thru in hull transducer- any thoughts on which is better. Anybody use an airmar P79 type in-hull transducer that you silicon a small tank to the hull and then fill with anti-freeze. A properly installed through-hull is more likely to stay in clean water than a transom-mount transducer according to Braffitt.
Whats more through-hull ducers are available in larger sizes than transom-mount models. Why is that important. Oct 26 2013 1.
I am considering mounting my replacement transducer on my SabreFTDs transom. The space is very tight in my bilge area. I guess I could remove the hoses.
Looks to be a hassle just the same. Also I am wondering why I have had three transducer go bad Lowrance and Humminbirds with through hull. 99 sure SidevuStructure scanSidescan wont ever work mounted in hull.
They have to be either transom or thru-hull. In my last boat I fitted a transom transducer in-hull using silicone and it worked fine Simrad GO7 and skimmer HDI transducer firing through solid GRP hull. The traditional 50200khz sonar setting worked well with.
Lowrance Transducers Thru-Hull Transom Mount Transducers. Lowrance XSONIC P79 Plastic Shoot Thru-Hull Transducer was designed for people that do not want to drill holes in the bottom of their boat. The in-hull transducer mounts inside the boat and will work on boats with deadrise up to 22 degrees.
From outside the hull thread the cable through the mounting hole. Then push the stem of the transducer through the hole using a twisting motion to squeeze out excess sealant. Take care to align the transducer with the bluntbuttonarrow end facing forward toward the bow.
