Demo Board $100.00 If you have coordinated with your Proteus Representative, signed the waiver, and have a time and place set up to demo a board, please place your order. This step must be completed before your representative will be able to get you a board. You will not be charged, but a hold will be put on your card to ensure the demo is returned. If you do not return your demo, you will be charged the full amount. Damage to the board can result in a maximum fee of up to $100 for irreparable damage. Rentals are free if they are returned within a day of the pick up.
