The Muddycreek Tackle Six Tree Standard Gimbal Rod Holder offers a unique tube system for a trolling rod holder, according to the manufacturer. Stating that other companies use thin-walled material for their trolling rod holder trees and crimp their tubes permanently on, Muddycreek says its heavier tubing is fully machined with a radius on the end. This detail on the fishing rod holder eliminates the need for a rubber cap and allows for easy removal of the tubes whenever necessary. The Muddycreek trolling rod holder system also incorporates an O-ring that compresses and absorbs vibration, preventing the tube from coming loose. This system is great for storage and rocket launchers, as it allows you to remove the tubes from the rod holders in just a few minutes, giving you clearance under the garage door.
