Snips,Hate to keep bothering you guys.I know your busy.Trying to get the best performance possible for bottom fishing.I have the TZT2 with internal sounder and a DFF3.I've had two different chirp systems with the B265.I'm not in love with chirp.I don't care about a arch or a blob.I'm a tone pulse guy.I don't have many options for a 33Worldcat Tournament power catamaran (35 mpr)My current 12M transducer was custom installed in a B260 faring,on your advice.It works perfect at speed.If I could install a 509 on my boat I would.I would just run 200kw fixed. Airmar said it's to big?I have room for a R199 in hull,which they don't make anymore.I've herd good thing about them.My boat is solid glass.I had a M265 and it worked pretty good.I know you guys hate inhull.The inhull R111,the tank is bigger than the old R199.I would have to modify stringers,and it might come to that.That is why I've been asking about the 82M.It's 2kw,5.5 degree cone,it's thru hull and I can custom mount it in a B260 faring.I want ultimate performance in tone pulse.Any suggestions?What would you buy at any price for bottom fish.Tired of installing transducers.Buy the best and be done? Thanks for everything.Capt.Mike
