Great company. Colton was very helpful in selecting a great paddle. Very knowledgeable.
★★★★★ Recommended on FacebookGot my wife's first kayak here and the guys were super helpful and friendly. Immediately welcoming and inviting — I can't wait to go back and browse their large inventory of kayaks and gear. Thank y'all for making our experience awesome!
★★★★★ Recommended on FacebookSo pleased with my Recon 120HD! Even though they're 2 hours away I had my kayak shipped to me. The packing was great and I received it undamaged. They were super helpful over the phone answering all my questions while I chose which kayak I wanted. Awesome company!
★★★★★ Recommended on FacebookI bought my first kayak (I'm 61) thanks to Parker's education and patience. He spent two hours with me and even after the sale continued to patiently answer my many questions and offer advice. I was completely at ease and enjoyed the whole experience.
★★★★★ Recommended on FacebookThe Mecca of anything kayaking and kayak fishing! I ordered a new kayak from their website and they had it ready and waiting when I got there. Very friendly and helpful staff, and the largest inventory of kayak accessories anywhere around.
★★★★★ Recommended on FacebookBought a great Nova Craft canoe here — a 3–4 hour drive from home but well worth it. It took them about 5 minutes to load it and strap it on my car and I was gone.
★★★★★ Recommended on FacebookYou guys rock — super fast shipping and my kayak got to my doorstep without a scratch. It was definitely packed with care! I'm already recommending you to all my kayak friends.
