Moose, you are absolutely correct. The latest trend now is to install 2 ducers each with a separate GSD26. The last 4 or 5 refits and installations i have done, the most common package is the B275LHW (low, High - Wide) and a R409LWM (Low-Wide, Medium) so now, you have all 3 level chirp frequencies L,M,H and you have a Low wide angle and a high wide angle. Now, this is a lot but keep in mind this is a bigger sport fish, the last boat we refitted, we installed 3x 8622 on the main dash, 2x 7612 on a drop down box from the hard top, 1 8617 in the cockpit and a 8608 in the tower. So this captain has 5 displays on the bridge....
his typical setup was to run the R409 with LW chirp on one display with bottom zoom, and the B275 with HW chirp on the next display with zoom locked at 300ft. The other 8622 was radar and the 2 overhead displays was chart and engine room cameras. So with his setup he is able to run dual frequencies and see what’s happening on the bottom and can then focus on the upper water column. What i did notice with this captain, he would very often switch between chirp and traditional because he was not convinced but was also still learning how to dial it all in. On traditional settings, the B275 High frequency is still Wide, so wether you are using chirp or traditional, the high is wide angle and on the R409, the low on either is wide.
