Installing a Transferable Fish Finder for Winter Pt 1

 

main-photoLate Fall through winter and into early spring, most species pull out of the shallows and hug some type of cover or structure in deeper, warmer water. They relate to rocks, logs, stumps, trees, ledges, points, and many other types of cover and structure that isn’t visible on the surface. The only way to locate some of the better spots is with a depth finder.

A really expensive finder isn’t necessary, for years I ran an inexpensive finder. It allowed me to differentiate between hard and soft bottom contour, water temperature, and water depth. I was able to mentally picture what was beneath and try to figure where fish would stage. In time I noticed I could really benefit from a unit with more features, at 3.5 inches my screen was too small, the built-in map was outdated, and because of the cone angle I could only mark fish in water deeper than 8 feet.

Being a long time consumer of Lowrance products I decided to stick with the brand and began looking for a unit with features I could benefit from for a while. My final decision was the Lowrance HDS 7 Touch Bundle, which includes the Structure Scan transducer. I’ve always wanted to create a finder system I could transfer between any kayak I own or use, so this HDS7 install received the treatment. The unit solves all of my issues and gives provides a serious advantage. To keep it short I’ll just say that it’s possible to spot the largest fish in an area, set a waypoint on its exact location, then go back and place a lure on its nose – this thing is dangerous!

Rigging an Attachment Point

I planned to design a custom aluminum mount to handle the Lowrance Structure Scan transducer, but a few days into the design I learned of RAM Mounting Systems designing a solution for us kayak anglers wanting to mount the LSS transducer. My design was scrapped and I began focusing on how to mount the LSS Transducer arm. This is what I came up with…

Benefits

  • Transducers are transferable between kayaks
  • Removable mounts make this perfect for kayaks that are transported upside down

DSC_0070-e1389026201890-300x199gt1-300x199gt2-300x199I installed an 8″ GearTrac 90 in a narrow area next to the seat of my Jackson Cuda14. There was no way to use a bolt/nut combination to secure the GT90 in this area, so I used an 8″ FullBack GT90 Backing Plate. The backing plate took the place of the nuts supplied with the GT90. With it, and the method used in the video, you can install a GT90 anywhere on a kayak.

This gear track is used with two YakAttack 1″ Screwballs. Two RAM Transducer Arms will be fitted to the screwballs, one for the 2D transducer and the other for the Structure Scan transducer. I decided to use a GearTrac 90 in this location because I want to be able to adjust the transducer arms when approaching shallow water, an obstruction, or if I hook-up with a large fish. The decision to install in this location also helps off the water, mainly when it’s time to flip my kayak upside down on top of my SUV. Once the arms and screwballs are removed there’s just a flat surface with nothing protruding. By installing additional GearTracs you can install your transducer(s) anywhere on your kayak.
