Default Simrad NSS EVO 2 Transducer Match

I am considering an upgrade to the newer Simrad unit and have been tracking down the appropriate transducer to match the capabilities of the interface. Seems there are some options, and I believe I have narrowed my search down to two, as follows:

1) B75 600 Watt Transducer - This will fit the existing thru hull from my old unit and provide the Chirp capabilities that are standard in the Simrad. My questions is what is real world depth performance if I want to get readings out past 1000', especially for swordfishing or deep drops?

2) B164 1 KW Transducer - I will need to drill out a bigger hole for the component and should get better depth readings out to about 1500', but I lose the Chirp capability.

Does anyone have real world experience with the B75 and some depth capabilities? Seems that is the better choice, as long as I can get some decent depth range?

It will be mounted on a 26 foot center console and used off the East coast of Florida, so looking for good detail in the 400' and shallower ranges, plus deepwater capabilities for swording.

Any insight is appreciated.

I agree with abbor & BoemarineBrian, hands down the best of both worlds with that ducer. Just installed a B175h but that's because we're only fishing in 200' or less and also are running a B744 and Structure Scan.

Abbor, have you used the NSSevo with the b175m?

Using the B60 as the bench mark...

The B75H will have 20 times greater round trip sensitivity.
The B175H will have 150 times great round trip sensitivity.

And for going deep the B175M is the better choice.

Can anyone provide some depth ranges for the B175M. Seems to be about twice the price of the B75. So with that price should I expect solid bottom readings out to 1500'?

Do any of the manufacturers provide depth ranges for the various units for comparison?

Also, in my reading it appears there have been some bugs in the Simrad units that required upgrades to resolve depth and temperature readings. Anyone completed those upgrades successfully and can report they are non issues on newly purchased units?

Thanks again for quick and consensus replies!! Not too often everyone chimes in with the same answer around here

Those are B175W shots. But the B175M should give very good results as well, and bottom at 1500' shouldn't be difficult for the B175M.
