Have an 06 puma, lowrance electronics installed at factory. I have put in a new HDS unit and was going to put the letters for the type transducer in the HDS and not certain which one it is. Its the shoot through at the back. No longer a tag on wire from cnit or at puck. Anyone know the letters to use ?????? Theres about 50 different choices on the HDS drop down menu.Thanks
