This is our Quick Detach upright and base plate for our SeeFish Transducer Mount 2.0 or 2.0 PRO. Your existing 2.0 arm will mount directly in this. This will allow you to remove the upright off of your deck if you are not using it to have a much cleaner and safer deck to walk on. This also comes in handy if you use a boat cover: the upright can be slid out of the base plate so that it does not get in the way and potentially damage the cover. 

• 2.0 mount comes with the thumb screws
• 2.0 PRO mount comes with the pin with leash and thumb screws
