Cannon Clamp Mount Downrigger Mount - Heavy Duty Fishing Rod Holder for Boats & Kayaks - Perfect for Trolling & Deep Sea Fishing

I bought this to put on my cannon lake troller base and it’s way shallow for the transom on my aluminum row boat. I bought the Scotty 1021 portable clamp bracket and it’s much better. 2 screws instead of 1 and it sits deeper on the gunnel, it’s solid. The bolts line up with the cannon base as well.It was easy to install and worked great plenty strong for holding my down rigger!There was no way this was going to stay on my aluminum boat. Little bit of pressure and it was falling off. Not going to trust if with my few hundred dollar down rigger. I ended up making my own mount out of wood on the metal bench seat of the boat instead of the rail. But if you can get this to mount good on your boat i am sure it is a good product. It just didn't work with my type of boat.Bought Cannon Easi-Troll down-rigger and this mount together. Bolts came with nuts and lock washer. Inserting bolts through Easi-Troll mounting base, the bolts were too short to even engage one thread with the lock washer on. This is not a cheap base. Really chaps me to have to spend even more money because manufacturer too cheap to buy and send the correct hardware. Fool me once not twice. Next down-rigger I buy will not be Cannon.Product description says 2" opening. Clamp doesn't open 2". Boat was in storage by the time I tried clamp and realized it didn't fit the seller says I can't return item that falsely claims that the clamp opening is 2". Very disappointed that the seller won't except return on item that doesn't do what they said it does 0.0 Stars for Seller.Highly recommend to adapt cannon down-rigger to small boat. Still at a little bit of an angle when clamped.Dose not attach very well to my Smokercraft side rail. I HAVE TO MODIFY THE BOAT for it to stay put!I bought two of these for our Pontoon boat. They attach to a support bar that attaches to the top bar. I went to a 5lb weight to reduces stress. Works great for us. We try to troll below 1.2mph, not sure what the impact would be on a heavier weight and higher speeds.Works well on my Lund but won’t fit some others. The jaw width is only 1 & 3/4 inches wide. Be careful, also I haven’t caught a fish yet, I wonder if my wire is making too much noise there is a lot of wire vibration now,Very good sturdy construction and easy to install.Great product works very well, easy to use.Good productWorks very well on my now seaworthy boat!
