My Garmin Striker 4cv 3D Printed Mount for my Fish Cat 4 Float Tube

When I used to own a boat I always like having a fish finder when I was out fishing so I knew the depth and could mark spots that I had been successful at catching fish.  After I had used my float tube on a number of trips I started to get the itch to add a fish finder and started to look into the smaller fish finders that were available and also started to think about how I could mount one to the fishing pole holder I shared in an earlier post.

For a fish finder I settled on the Garmin Stryker 4cv.  This fish finding had all the basic features I was looking for (and more...) and was small enough that it wouldn't be to big for my Fish Cat 4 float tube and I could power it with one of the batteries from my Dewalt cordless drill that was small and would easily fit in one of the pocket on the Fish Cat 4.

To mount the fish finder I was able to design a set of mounts that I could add to my fishing pole holder on my ViaCad 2D/3D modeling program.  I'll explain how each of the parts is used later, but the pictures below are what the parts looked like when I finished designing them in my modeling program.

The following two pictures are of the top and bottom of the mount that that the bracket on the Garmin Stryker attaches too.

The next picture is the three parts that make up the mount for the transducer.

To actually make the mounts I printed them on my Prusa i3 MK3s+ 3D printer.  I picked up the 3D printer a little over a year ago and now that I've owned one I don't think I could ever live without it. 

The design I came up with is pretty straight forward and consists of a mount that screws on to an ABS fitting that is attached to the top of the forward most vertical tube on my pole holder and then a mount that clamps on to the lower end of that same tube for the transducer.

Here is a picture of everything installed on my Fish Cat 4.

Here is a more detailed picture of the upper mount.  Since the transducer cable annoy be shortened the vertical tube the Garmin is mounted to makes a great place to tuck away all the excess transducer cable.

The following picture is of the lower transducer mount assembly.

The lower mount is attached to the 1-1/2 inch ABS tube by the two 3D printed parts that are clamped on to the tube using four small stainless bolts.

The transducer is attached to the lower 3D printed part by two small stainless bolts and the the upper and lower mounts are connected together using a section of 3/4 inch schedule 40 PVC pipe that slipped into to each of the mounts with quick release pins.

If I don't want to use the Garmin it is very easy to remove it by just using the release on the Garmin mount and then disconnecting it from the lower mount using the quick release pins.

I also made a video that is available on YouTube that provides some more info and shows how the brackets are installed.
