I recently upgraded to a combo fish finder GPS unit. I was using a suction cup to hold the transducer to the side of the W but I noticed it would create drag and occasionally fall off. I tried several different methods to mount it in the inside of the W and shoot it through the hull, not so successfully. Again sometimes the simplest method works the best. I wish I would have tried this first. On YouTube tube I noticed a installation using duct seal. I purchased 1lb. at under $3.
Simply form a well at the bottom, lay transducer flat to surface , pinch some of the duct seal over it to hold in place. When you start kayaking simply put a slight amount of water in the well you formed to cover bottom of the transducer and start enjoying drag free readings. This duct seal sticks great, is waterproof, remains soft, and is portable. If you want to move it to another W simply peel off and reset it.
Been tying up some fun hopper patterns. Since we are in SEC country, had a little fun tying some hoppers in school colors. Check out the Blind Hog, the Big Orange, Tiger Bait and the Crimson Critter. All have typical natural water profiles to match the bug at the time, tan, green, yellow, or pink. For some reason Southern trout love pink.
Some pictures of a local hottie catching some of our trophy trout during the hopper bite.
