Default B60 versus B164 help

I have read a lot of threads, talked to vendors and even called Airmar and I need to make a decision soon. I am waiting for my Navnet 3d/ FCV585 combination to install on the new 24' boat that is sitting and waiting. At this point I have on order a B60-20 but have my doubts that I should be switching to the B164-20 which has been recommended by the vendor and Airmar. I am new to bottom fishing so I really do not know what I will be happiest with in the long run. I like the idea of the better, sharper image with more detail with the B164 but am concerned about the small cone for the fishing I anticipate doing. 90 percent of the time I am going to be in the lower Chesapeake which means mostly less than 50' of water and certainly less than 100'. Occasional ocean trips I do not see going much beyond 100' in this area as you have to go pretty far to get to 30 fathoms on the chart. Previously all I have done is very shallow water fishing, but with the new setup will be switching to mostly bottom fishing and I want to find structure, wrecks etc. Can those with real world experience give me some advice?

I just faced same decision, and I do fish offshore in 600+ of water once in a while.. B60 was my choice, cause 90% of all trips we are in less than 300 of water.. Plus drilling 5" hole in the boat made me a bit nervous..
Good luck, Furuno NavNet 3 is suppose to be sweet...

The B164 requires a 3.75" hole. For bottom fishing/finding structure the narrower beam width of the B164 will help you to get on top of things better.

I had to make the same decision. I went with the B60 as the deepest we have in my area is 200'. If I move to the east coast (Australia) where the water is deeper, it will be easy to drill the hole bigger for a B164.

I have one of each, a B60 on my Furuno 582, and a B164 on my Furuno DFF1. The bottom resolution on the B164 is better, even in 100' of water. As far as speed, the biggest variable on that is the design of your hull and how optimal the transducer was placed - if it is between 4-8" off the keel and in the aft third of the boat with absolutley nothing (intakes, strakes, etc) anywhere forward of it, it will be good for 30 kts or more; if not cavitation will kill it at planing speeds.

I am hopeful that others using either the B60 or B164 can give their opinion of whether the B60 should do the job for me or am I better off sinking the extra $ into the B164 and getting it done now. Does the cone size difference at 50' of 5 feet (B164) really make a difference to the 11 feet of the B60 or is the better image more valuable when finding structure to bottom fish? I appreciate any help offered.

I'm in the Mid-Bay and have a B60 on a Furuno 582L. The decison for me was easy since I didn't have the power for the B164.

With that said, I have no problems putting fish in the boat with what I have

For shallow water the B60 is probably a better choice as a 5' cone on the B164 won't give you much of an overview of the structure you are trying to fish. The B164 is used mostly by me for deep water 500'+ offshore fishing. In the bay on both of my boats I have B60's - 1 on a Furuno 582 and the other on a Garmin GDS 22.

Thanks LI32, that is the kind of insight I was hoping for. I think it might be best to start with the B60 and get some experience with it. I can always make the hole bigger, but not the other way around.

I have the b60 20 degree offset and am very happy with the performance and it will show bottom at 40MPH, the water I fish in is anywhere from 15' to 100' deep. Just make sure that the arrow on the transducer points toward the keel of the boat or you will have side scan sonar.
