So rather than carrying all my lines on extra spools I'm in the habit of carrying two rods completely strung up and ready to go. With this setup I can quickly change between two different line types and increase my odds of catching fish. As flexible as this is, it can be a real hassle unless the secondary rod is stowed securely out of the way. In order to do this a rod holder is a requirement. The HSI rod holder is an example of the principle the whole is greater than the sum of its parts .
First inspection reveals a conspicuously simple design.
A Nylon strap is threaded in and out of the saddle a couple of times effectively hiding the head of the bolt preventing would be abrasion. The strap includes a sturdy buckle for easily attaching around a float tube. Throw in a Velcro leash that helps hold the rod tube at the preferred angle plus adds a bit of security locking the rod into the tube. And there you have it. If you're feeling really creative you can strap it around your waist for use as a third hand.
