Title: Help choosing shoot thru
Post by: Goingbig on August 20, 2011, 11:09:45 AM
  Hey everyone I have had my 998 Si for a little over a year and I have loved it!  I currently am using it paired with two transom mount transducers (xhs 9 hdsi 180).  Only thing I have had problems with is getting high speed bottom readings.  This is expected with transom transducers.  I have recently been debating using a AS SI DB Y paired with a shoot thru for the 2d at high speed.  My question is basically which shoot thru would you suggest?  I fish saltwater out to about 150ft.  I was looking for forum post reguarding shoot thru transducers and saltwater results and couldnt really find anything.  Anyone out there use it?

Goingbig; SI does not work as a shoot thru hull (in hull)install.
You may try a thru hull with a HB XTH 9 DB 35 KW T or a XPTH 9 HDSI 180 T, big hole in the bottom being a thru hull.

If the boat hull is single layer (not multilayer) a in hull may work but may have diminished returns in 2d. SI will not work!!!!

Hope this helps a little.  Roddy
