I think it goes without saying that I was super stoked to be running a great big 2kw sonar in the new 42 last season! I went with the R409LWM keel mounted CHIRP transducer powered by a Raymarine CP-570 Sounder and displayed on a pair of Axiom Pro 16's. This is a home-run setup with 40* of beam on the low freq and 11*-13* in the medium. The disparity between the two beam widths proved to be key because it told me when I had "fish around" me, albeit in a very wide zone (low freq), but also when I was right on target (med freq). And many times one frequency would show me something that the other did not, or give me a different look at it.

Ok, so here are my top 40 sonar shots I took last season on my 2 channel, Raymarine 2kw Sonar. Yep, the 40 best. To many of you, some of these shots aren't all that exciting, but to me, EVERY one of these shots is fascinating.

The reason being is that regardless if any one of these shots is showing something really impressive or not, every shot here shows me a great deal of perspective between the two sonar channels, further proving that running a 2 channel sonar is KEY. And in many cases, if I had only been running a single sonar channel, I wouldn't have seen anything at all, even though there was actually something very important there to see, the thing I look for tirelessly from lines-in to lines-out everyday, something that sends us from clients dozing off in their seats, to tuna tails pounding the deck, fresh tuna hearts and red sno-cones for all!

I cant help but to wonder how many opportunities I’ve missed during all the years I was only running a single channel sonar. How many times I kept on trolling, oblivious to the fact that there was the exact thing I was hunting for right under us, the key ingredient to why we were all out there, the difference between a big goose egg and a blood bath, smiles, fish to take home and clients for life.

One thing is for sure, I'm a 2 channel guy for life and my confidence out on the water was 10 fold after installing this system!!!

Here's to 2021!

I just added a 3 in 1 skimmer with my B175HW. Initial results are excellent! Can't wait to experiment with a 3 way split. High CHIRP, Low(or med.) Chirp and down scan.

The M is good, but adding the HW for the wider beam like Mark mentions above. Here’s a shot with the b175m on a bait stop.

The B175M is a great all around transducer/frequency. We have several in our fleet. Adding an HW will really up your game. Good goin. Let me know if you questions, etc.

Hey Jeff...what’s this 3 in 1 skimmer?


Hope this link works. Otherwise look up Simrad activeimaging 3 in 1 transducer.
Make sure it is compatible with you MFD.

On the sounder when in contact with the bottom why not tighten up the bottom range from 90ish up to 70 you'll get a bigger view and more detail

are the two frequencies set at different gains? I just got the 275 LHW so trying to figure out best setting thanks, mines only 1 kw

In the case of the shots above of the rockfish schools, I want to see the total volume of the school vertically. I’m not looking for a specific bottom feature I need magnified or need to see little scratches of fish.

Can you elaborate on the importance of sonar and radar working together? I just getting familiar with my b175hw and I'll be doing a closed array radar of some kind this season. Interested in your opinion on radar selection. ( Running EVO3'S)

I guess I'm confused, if the transducer is a LHW ( low and high wide), where's the medium frequency your specifying?

Until you get into an open array radar its pretty challenging to see bird and foamer schools at any kind of range. So if you’re set on a closed array dome I’d expect great vessel and land targeting but little in the way of bird/foamer targeting. I’d highly recommend this unit here, comes with Doppler Collision Avoidance. Cool stuff. https://www.raymarine.com/marine-radar/quantum2.html

If you want to step it up and “see everything” and see it at range then this is what you want.

I'm running HW and Medium in conjunction most of the time. Many times in fixed frequency to lock in on the target species.

There's a demo magnum on ebay right not for $3K, I feel like I'm dropping the ball not grabbing it. I just don't have room for that beast on my 24 Skippy. I really don't need the distance that provides either, farthest I go is a SCI. I've got about 500hp and I'm fast for a skipjack but if there are birds / foamers 10 miles away I'm not getting to them by the time they are gone, hell 5 miles even. I'm assuming that's the case for most people and the distance is not really what you're after, it's better return separation and clarity right?

Yes sir. The gain settings are different on each frequency and those settings are constantly being tweaked through out the day. I’m typically tweaking the gains every 10 minutes or so, trying to have just a light scattering of “popcorn” on the screen at all times.

Right, the bigger goal would to see birds/foamers with better separation and clarity. Realistic range to getting to something like that is 1/2-2nm I’d say, if spotted on your radar.

Ok I guess I need some education on what to look for on the screen shots. Where can I do read and do some research?
Hey Tom, there’s some general literature out there on the web. I’m happy to talk you through some of those shots sometime in Westport, May-September. Float 14. Message me and I’ll make it happen.

    Thanks for helping set up the fish finder on the boat this summer. We have to have you stop back by and fine tune it again. Someone monkeyed with the setting a bit. I would love to come out one day and just watch you run the electronics.
