My wife bought me a Garmin Echo 100 fish finder for our anniversary a few weeks ago.
I’ve never had to set up a fish finder before. I have a pretty good idea where I want to install the module itself. My questions are about the transducer.
The transducer it comes with has an option to mount it to the trolling motor. My concern is that we occasionally play around in some pretty shallow water. I’d hate to go through all the trouble to set up the transducer on my trolling motor, just to damage it on some shells or other underwater debris.
I just heard that there is an optional transducer on the market you can buy for light boats that allows you to install it in your bow on the floor, (on the inside). It supposedly works through the boat.
Has anyone else heard of this or are familiar with them?
Am I missing the point here, that in small boats we can get away with simply gluing the transducer to the floor?
Thoughts on installing the transducer on the trolling motor given shallow water applications?
(Can you tell I live life confused? LOL)
You can place your transducer in your bow and companies like Hummingbird have a kit for you to install, though I have heard mix reviews on it. The trick is to ensure your their is no bubbles (air bubbles) between the transducer and the hull which can cause false readings. I believe you will not receive accurate water temps from inside the hull. Good thing is that you don’t have to worry about your transducer bumping into anything (rocks, trees, etc..). There are some great ideas on the forum where member have built a “arm” that hangs over their ride into the water but also allows them to swing it up or pull it out altogther. You can also run it through one of your scuppers and you can get much better readings but suseptable to the rocks and trees. Mounting it to the transom is a good idea but like you said if you just want to paddle and fish you will have to change/move your transducer. I would search these forums and Youtube they are both great sources. Everyone here is very helpful.
The video and info was informative, but it leaves questions.
Since our NuCanoes are “dbl hull” construction, how do you feel that would affect installation inside the boat?
Wouldn’t that cause the same problem of having bubbles in the contact material?
CC, Go to Rigging & Installation and look for “Fish Finder Idea’s” There are several choices there. I mounted mine with silicone as I have before on other yaks and small aluminum boats. They can’t be hit with that type of install. Temp’s are about 2 degrees warmer when I’ve checked against direct contact ones. I’ll try to get pics up and running as I’m computer illiterate. Some other guys use plumbers putty instead of silicone. Good Luck!! ack-yak
Brandon Roberts did an install under the front hatch and ran the electrical line through a grommet he drilled into the gun wales of the Frontier. He said that it works great and has had no issues.
Here is the thread: http://www.nucanoe.com/forum/o…..as/page-2/
Lots of ideas and links to other ideas.
The interior-hull mounts I am seeing seem to be mounted to the bottom of the hull that is in contact with the water, this isn’t possible in the Classic.
I just don’t see how trying to get a decent reading through two hulls will work.
I think I’m just going to have to bring it with me and experiment with it to see if interior-hull mounting in the classic will give me anything close to a decent reading at all.
My final choice would be just to mount it on the trolling motor and see how long it will last.
CC, Send me an PM with an e-mail address and I’ll send my photo’s of my install. In the pic’s you’ll see my watertight deck plate inserted on the floor. A friend of mine, “jusanglin” has a NuCanoe with a deck plate he installed on the side deck next to or near his seat location. That gave him access to the interior. It’s not very hard to do. Pm me if you are interested. Bob
I have a classic and have mine mounted inside the hull. I put in a 4in access screw in hatch to get access and another small hole to bring the transducer wire back through that is sealed. It works great. As to a mounting kit for inside hull, don’t bother and you also do not need to silicon it. I use electrician’s putty. I put a ball of it and then press the transducer into it when it is on the hull. There are no airbubbles and it stays in place fine. Also if I need to relocate it simply removes and I can restick it else where. As ack-yak said the temp readings through hull are off a degree or two, but that is not bad at all. I will take some pictures and post them soon if you would like.
Cajon I hear with the fear of cutting a hole. I had the same fear, but finally I just went for it. I have the hole sealed well with silicon and have had no leaks. Here are some pictures:
This shows the set up. I placed the hatch just forward of my seat so it is out of the way. I have the battery on the deck in a waterproof box. The fishfinder mounts on a RAM mount so I can move it around on the boat as needed I left enough transducer cable out to be able to move.
Here’s a closer look at the unit and battery box
here is the hatch with the sealed cable outlet as well.
This is looking into the hatch where I mounted the transducer on the bottom pressed into the electrician’s putty.
like I said it was a little scary cutting the hole, but with a good clean cut and plenty of silicon, it has worked out great.
Nice work on your NuCanoe, RAM sells the transducer arm that many on here have built themselves if you feel like buying instead or you can look at the Liberator from Mad Frog gear. You can mount it on a gear track on the top edge of the boat or build a mobile platform.
We all have our preferences on location of the transducer. My reasoning for in the hull are it’s completely protected. Look at my avatar!! My Frontier see’s it all, gravel, branches, salt marsh reeds, etc. And it still reads temp’s OK, maybe 1/2 degrees different than actual water temp. No matter which way we do it, WE ARE FISHING AND HAVING A GREAT TIME!! AMEN!!!
