The Hook 2 is a great product for those that want to really understand the structure of any lake with great screen resolution, mapping and abilty to operate the GUI. I am very impressed. This will serve any 10ft Kayak to much larger boat on the water. Of course you can spend a ton more money if your so inclined or need. Mounting the head unit was simple of the deck of my SOT Pelican Catch 100; easy-peasy. The transducer on the other-hand was the "Journey" First I didn't want to have to buy mounting arms to hang it over the side. For one the mounting arms out their for Yaks are designed for much smaller Transducers such as the SplitShot. Also having crap hang over the side of a Kayak is no fun when you're fishing shallow waters or have a 6lbs LM Bass wrap itself around the transducer. These transducers and the mounting hardware are more designed/engineered for a traditional John Boat or other square & flat sterned boat; they simply were not "design" or thought to be used on a Fishing Kayak. So? I was determined to have this sit on the bottom of my hull and utlize one of the Scupper holes to feed the transducer cable in a clean install without mounting arms or cables all over the the Yak. So before you read on about how I solved my Transducer install, let me finish with saying that as a sonar/scanner "Fish Finder" the Hook 2 is a great product and will serve even a tournament fisherman(woman) well. Read on for the install and hopefully the attached pictures or of some interest. The following are excerpts from two other product reviews of items I bought to assist in the install.The "Journey":Review of the Lowrance 000-10606-001 Kayak Scupper Mount for Skimmer Type Transducers:The Lowrence site make no mention that this product works only for a SplitShot transducer. Fortunate as an engineer with the right tools I was able to modify this to work, it took some out of the box thinking. I used this along with the BerleyPro Hobie Lowrance Triple Shot Transducer Mount for the installation I wanted. ( I have also copied for your information if this helps, my review of this mount) The bottom mount for one was too narrow and shallow for the TripleShot as the connection gear is larger on the TripleShot. Let me say if your using a Splitshot this product is Perfect! and easy to install. I was fortunate to have a hull shape on my Kayak that allowed my install to work with some cutting and engineering. Not the biggest of deal breakers, but really required me to think this through. The Pictures show what I am conveying. The BerlyPro mount is needed for a bottom hull install as the TripleShot would be exposed to potential damage from shallow water of getting the Yak out of the water and the weight of the TripleShot would not be adequately supported from this Lowrence Scupper Mount. My biggest complaint was the Tech-Staff at Lowrence was completely unaware of this in the least bit what-so-ever. They were dumb-founded.From review on the BerleyPro Hobie Lowrance Triple Shot Transducer Mount -BP2610:I was fully aware that this BerleyPro Hobie Lowrance Triple Shot Transducer Mount was for a Hobie Yak. However, the triple shot is much longer than a split shot of traditional chirp/down scan only transducers, thus, using arms hanging over the side of your yak from Yak-Attack or Scotty leaves it prone to movement and requires constant adjustment, especially if your fishing through heavy weeks flipping and pitching or shallow water. I used and adapted this to the bottom of the hull for my Pelican Catch 100. Fortunately the bottom is dead flat and I was able to adapt this to sit not only on the bottom but to have the mount utilize one of the scupper holes for a clean install. the two side pontoons of my hull leaving this safe from hitting the bottom. I attached this product using Well/Hull nuts and a combination of 3M 5200 & 4200 Sealant. Works like a charm! If you own a Hobie, your in luck! the Hull is already formed to receive this and all you need to do is screw it in with the factory installed hull/well nuts. Good Luck
