TRANSDUCER HELP PLEASE!!!!!

HI guys,

I'm building a new boat and installing dual Garmin 7612XSV units.
I personally like the Garmin product and am very used to it having had 8212's, 7212's, etc.

My dilemma involves the transducer/transducers.

I bought the XSV units to eliminate the GSD boxes.

I would like to have SIDE SCAN , CHIRP as well as just reading depth and temperature.

The ideas are to have 2 transducers installed.

Here is my issue. There are sooooooo many units, my head is spinning.

I was told to look at the Airmar B175C-20-HW for side scan and chirp and the Airmar B175M for just basic operation.

Does anyone else have ideas, suggestions or comments (negative or positive) to share please?

Also, they will be in a 31' or 35' Twinvee Catamaran and was wondering if the transducers will interfere with each other.

Lot's of questions but I'm a real novice when it comes to the new equipment, I'd appreciate any and all help.

Thanks much

Cheers

Eric

    If you would like the best possible quality answers to your questions, you might try to include some more information on the depths that you want to reach & the resolution that you are looking for at various depths. Changing frequency ranges will give you a trade off between depth & resolution. Increasing power can improve both depth and resolution at the same time. Very high power transducers often require separate power feed wires. If possible, those extra wires are something that you want to plan for before the boat is rigged.

    You also might want to start thinking about if you want thru-hull, shoot through the hull, or external mount transducers. Shoot through the hull gives the cleanest installation, but usually gives reduced performance, prevents the temperature sensor from working properly & can create issues with heat dissipation, especially on the high power units. Thru-hull units require you to punch holes in your nice new hulls. External mount units have their own set of obvious issues.

    Hi Eric

    I have the Garmin 7610xsv. The transducer I chose was the Gt51m-tm. Which is the transom mount with 3 elements, so it has chirp/side scan/ down scan. Marks great while running and I have marked up to 1500'.

    Eric,
    I've got the Garmin 7610xsv in my boat now. I recently (Thanks to Remel198) on the south section of this forum, put an AIRMAR B-175-M in my boat. It puts out a KW of power. Previously, I had the B-75-H, but that ducer is only good to about 400 feet.

    The difference in performance is like night and day. I was reading bottom to 980' while running, something I haven't been able to do before. That unit is a CHIRP unit as you know. It will require about a "4" (FOUR) inch HOLE in the bottom of your boat.

    It runs about $1300. - I got it through "Semperfifishing" on the hull truth. ($896.00 delivered the next day!!!)
    The guys name is Gil Travis.

    Now.... I know you are a Garmin fan, and so am I... BUT, if I had it to do all over again, THIS is what I would buy:

    http://www.thehulltruth.com/semperfifishing-marine-electronics-transducer-sales/855931-furuno-dff3d-4th-july-sale.html

    It's the newest, latest and greatest from Furuno. It's got 3-D resolution.

    Anyway. Give the man a call. There are tons of posts from people on THT giving a positive review of him. You won't get a better price on equipment either.
    He's an electrical engineer and knows sonar and GPS technology intimately.

    And, he will be happy to enlighten you on any issues from equipt, to the installation in a twin-vee hull as well, including any conflicts between transducers.

    For the record. I have the B-175-M (thru hull), coupled with the GT-30 transom mount for side/down view.
    The GT-51 M tm will actually be a better choice for your transom mount unit.

    Give him a call. Let me know how you do. (Think Furuno!) :grin

    Pura Vida!

    We are running Airmar B175 HW and a B175L thru hulls.
    Great bottom read but the installer I referenced in other post runs a 3KW in hull
    and swears he can see a sword take a dump at 2000' ???

    Be wary though if you equip too well there are fewer excuses for not catching.
    That's where I am ! ! !
    Talk soon.

    Jim,
    Hey buddy, I wasn't specific enough even though I already knew the application I needed. It will be a Thru Hull and I have it narrowed down I believe.

    Jim II,
    I was really looking at that UNTIL I spoke with Gil Travis who Big Bill recommended. Having a Cat Hull, makes it an impossibility to mount since it needs to be between the engines according to him. Thanks for the recommendation and the call out.

    Bill,
    Great recommendation with Gil Travis. I spoke to him and see my response to Lance below:

    Lance,
    I spoke to Gil Travis who Big Bill recommended and he recommended the following believe it or not:

    B175HW for the CHIRP transducer which is good for bottom fishing up to about 400'

    B175L which is also CHIRP and will paint at least to 1500' (he said maybe deeper depending on the install, etc)

    Its interesting that this is the same setup you have so if you don't mind, may I call you tomorrow to pick your brain since I might have to take a loan out to purchase these 2 guys.LOL

    Cheers

    "I might have to take a loan out to purchase these 2 guys.LOL"

    One more thing comes to mind since you mentioned the above.
    You want to make sure of the dead rise angle if that is a consideration. If the transducer will be mounted in a flat area of the hull, then obviously a "0" degree unit will prevail.

    Let us know what you end up with.

    I have the Airmar B 175m on my 26 Twin Vee. It works very well. Easily reads in over 2000 ft. It was reading the bottom in 2100 ft running back from the Bahamas at 28 mph on a glass calm ocean.

    Fireman Bill,
    I just got the same unit installed recently, havent had an opportunity to thoroughly test it yet - that's great news to me - thanks!

    Hello all, I am having a Garmin 7610xsv and GT51 installed next Monday and will be adding either the B175W, M, or L. Trying to figure out which one is better or maybe going with 2 of them if I can’t decide. I plan to troll, bottom fish, and deep drop here out of PE and all SEFlorida and at some point Bahamas trips as well. I was thinking the M but not sure what I’d be missing compared to the W in waters 300 feet and under like reefs and wrecks. If the W is that much better than the M I’d probably get both if not that much better in those depths I’d just go with the M. I need help.

    Thanks

    Just do a B275 and have the best of both worlds in a duel frequency unit?

    Hey Eric,

    It’s been a bit, how you doing?

    He is what got installed on Shoeless 3 (Hydrasports 2800 Vector WA):

    2 x 7612xsv
    B175H
    B175L
    GT51
    12kw 4 Ft HD2 Radar
    Plus, a killer stereo and of course autopilot.

    We do similar fishing, but here lately Lana and I have been doing more bottom fishing than trolling. For this reason I chose the 175H, if I was doing more trolling and wanted to spot fish in the water colum as I trolled, I’d probably go with the 175HW.

    The nice thing about the sxv as you have mentioned, no sounder box. Each unit can run 2 transducers, 1 x 8 pin and 1 x 12 pin(I think it’s 12, but could be wrong). So for me, I opted for 3 :). So now I have all bases covered 1kw CHIRP L, 1kw CHIRP H, 600 w CHIRP M, and down and side vu.

    We have probably fished the boat about 10 Times this year being it took me all spring to finalize the purchase of the boat and all the rigging. I only need 4 more rod holders welded in and it’s 100% ready to go chase YF Tuna in the Bahamas. So far I love it. The downvu/sidevu is amazing. I can spot bait balls to the sides of the boat when catching bait, see barges/pipes/rubble when bottom fishing. I have yet to flex the muscles of the 175L yet, but I expect it to be absolutely amazing DD in the Bahamas.

    On a separate note I bought nearly every component of my electronics from Gil. He is a standup guy and will get you the best prices hands down.

    Good luck,
    Sean

    Gil knows his stuff...

    Wow - you went first class Sean!

    Let me know how you do deep dropping with the 175-L - I'm curious what it will show on the bottom when in the target zone. Also, if you can recommend optimum settings. And, how it compares to the B-175M over the same locations.

    Thank you Sir!!!! I figured it was time to step up to the plate and rig a boat the way I have been dreaming of fishing ever since I did an YF Tuna Trip with Pat Price many years ago. Its hard to believe that only 6-7 years ago I was in my 20 Ft. Century dreaming of bigger boats and now here I am.

    I haven't been on the forum much as I picked up a new side project when fishing is a bit slower in the winter times. Its a Factory Five Racing GTM Supercar. This thing is a beast and I have been plugging away at the build for the last few months.

    That is cool! I'm sure it'll keep you busy as well - congratulations!

    My son's shop teacher in high school built a Cobra kit car with a 400+ ci engine in it. Cool factor was off the charts...

    Hi...i am a new user here. As per my experience you can try to include some more information on the depths that you want to reach & the resolution that you are looking for at various depths. Changing frequency ranges will give you a trade off between depth & resolution. Increasing power can improve both depth and resolution at the same time.
