hey guys, so i had a post on here in regards to losing my depth at higher speeds on my boat. Basically once i get on plane, i lose my depth. My plan is to play with transducer location, tilt, and position first. Then, if need be i'll buy another ducer to enable me to have depth at higher speeds. So, i called hummingbird today and asked questions about ducer location and shoot through hull ducers. The kind lady responded that i would need to purchase a XP 9 20T (temperature) transducer and cable as-si-db-y. I can not find this cable on their website. The unit i have is a new 998 HD SI with the transducer that comes with it. so, what cable do i need if i go with the shoot through transducer? is this the correct transducer and cable that she told me? thanks guys, hopefully before too long i'll be able to post with some helpful suggestions instead of all these questions before too long
