HDS7 - Which Transducer

I was at Cabelas this weekend and a rep from Lowrance recommended that I use the menu options to select the actual transducer model. His comment was that the tag on the transducer cable would tell me what model I have in my boat. Well the tag did not match any of the models listed on the menu. I ended up selecting Unknown. Anyone have any comments or suggestions?

Have a look here: http://store.navico.com/Search/hds-7 There are a number of different through-hull ducers. I believe the number on your cable should match up with one of the part numbers on the website. The model id is included in most of the product descriptions, which is what you want to look for and select in the menu on your hds7.

The transducer for the HDS7 is a shoot thru the hull transducer.

I have mine set up as GEN 200 . This what Doc Samson says to set it on his videos . I have both videos and they are worth the money.

There are a number of different styles of transducers that can be used on your unit. More info is needed. Is it a skimmer? Dual beam? etc... If the transducer came with the unit, then it should be in the manual or on the box somewhere. I bought mine online and it listed the ducer model right on the order and the invoice. If you can't find it using the sources I mentioned then post the numbers that are on the tag you mentioned.
