This is where I finally decided to mount the Garmin Fish Finder on my Slayer 10… I found this to be the best spot for me since it does not use up any space inside the deck area of the kayak. It was really cheap and simple. I have another Garmin mount for my Hobie PA so it is a simple process of un-clipping the Garmin itself off of one mount and on to the other.
The transducer, which is mounted to a simple flat aluminum bar, simply swings up and out of the way when not in use. The bungee on the handle is used to hold it in place.
Using the stock accessory rail, two brass t-bolts hold everything in place.
