I am trying to find the same thing.  I came across this fish finder with chirp and gps on sale at west marine:

Very positive reviews on multiple websites, but it comes with a transom transducer.  The catch for me is that I will have to do a in-hull mount on my revo11... any update on what you decided on?

Right on guys, I think I will give it a try on tomorrow morning's outgoing tide.  I purchased my steel head card at the the beginning of the year but have not given it a go... feel free to pm me for one of those adventures.  Since moving here fishing is about all I have been doing other than job searching.

I mostly fish between 121 and 12 bridges. Horseshoe bend slough is often full of schoolie sized stripers with an occasional double digit.

I am browsing the satellite map of the area and am unsure of what bridge would be considered the "121" bridge (I am guessing it is the same as W. Imola ave...).  Last time I went out I petaled south of the 12 bridge and then hit horseshoe on the way back (incoming/high tide).  I will have to give horseshoe another shot on the outgoing tide, I recently upgraded to a revolution 11 and that quelled my worries of traveling against the current.  I also only have a floating line currently so I will order a sinker to put on my extra spool.  Thanks again!

I just recently moved to Vallejo and have been trying to hook into the striped bass.  I have managed to catch a few on swim baits, but my goal has been to get the fly action dialed in.  I have only tried the Napa river so far, any tips trips or ideas are welcome!

Kiel, right now I live just on the east side of hwy 80, but will be moving close to the causeway once the new place becomes available.  Do you ever go for Halibut in Tomales bay, it is getting pretty high on my current priority list.  Cheers- Joseph

New to the forum and to Vallejo, looking forward to exploring the delta and catching more fish!
