Default Anyone use a Airmar b175 ?

Wanting to upgrade transducers, looking at the b175M. Fishing depths 120-450' . It will be paired with a 7610xsv. Anyone have any feedback on this ducer ?

The B175M is a great cross duty transducer. Are you fishing water column or bottom?

Both, but I would like more detail at the bottom at 300-450ft for finding some good bottom for deep drop

Here are a couple of screen shots from my 7610xsv and B175m. Also take a look at my thread about this setup for more shots and info!

Great combo for what you are wanting to do!

I have the B175M / 7612xsv setup on my boat. Can't help you with the deep drop but have been very happy with the performance in the 20-80ft range. I know this part is boat dependent but I get a rock solid picture up to 30 kts and then I start to lose the bottom. At 33 kts I need to switch over to my B260 with the nice big fairing block. Not bad for a flush mount transducer.

You should definitely consider the B175H - the narrower beam width is better suited for bottom detail and it will have no problem out to 450ft depth.

Here is one that I took showing the B175m and the GT51 in deep water! Works very well!


2) Deep water shot in 1001 feet with the B175m.


3) Split screen shot in 655 feet.

Awesome deep shots! Have you tried a single freq in deep water? If so is it any better? There are some good GT51 shots in deep water using 80khz.

Thank you! No, I have not tried a single freq, I mainly run the 7610 in auto settings. My plan is to start "diving into" the custom setting more in the near future!

Either way, those are encouraging screen shots of the 175m. I've posted questions about the deep performance and this is the first time I've seen real images.

thanks

Here are a few more that I have! I will look and see if I have any more shots in really deep water!

This is the only other deep water shot that I have saved on my work computer (I may have a few more at home). Not the best shot, but I was trying to capture the fish hanging on the drop off. Not to bad for the B175m at auto settings!

Can you track deep bottom on the move?

Yes, but not great. Tracking bottom and getting good returns at speed is the only complaint that I have with my setup. I have talked at length about it on the thread I started a while back. http://www.thehulltruth.com/marine-e...ics-added.html


Here is 630 feet deep going 21mph, it is ok but not great.

You are very welcome! Let me know if I can help in any other way! I have been very happy with the M.

like everything else, no transducer is best at all things...pick what's most important to you and go with that. if bottom fishing 120-450' is priority 1, then the b175h would be the pick.

also consider that you will likely have a cv/sv transducer with a 2D chirp element built in and most of these are Medium chirp...which means that you're essentially wasting this element if you have a b175m as it is redundant. pairing a gt51M w/a b175h gives you medium and high chirp coverage and angles from 9° all the way through 24° depending on the transducer & frequency you select (which you can control from the unit). gt51M & b175h is a great combination for the fishing you describe.

Given the same conditions after doing a lot of research I went with a B175M and a GT51.
