It would love to see the actual difference from a 1 Kw B175 HW Vs the Gt51 maybe @fishbadger can comment on the 600W vs. the 1Kw these screens provide high resolution.
run the best transducer you can for your fishing I think for salmon and halibut the airmar 1Kw B175 HW would be the best but it's a big hole to drill
Yes it's definitely a big hole to drill!
I think the MFD provides full power to each port (ie. 1Kw to the B175HW while the other transducers are working). I would have to check with Garmin to be sure.
The resolution on the HW is excellent. I think it really shines for salmon fishing, as you can readily sift through bait balls and pick out the depth the salmon and other targets are, within and at the edges of the feed. So finding bait and suspended targets is where it really shines. While it can find bottom just fine, even deep and on the run with the thru hull, it has such a wide cone (for searching), that it may not be the best ducer for precise bottom fishing, particularly around structure. I run into some artifacts sometimes with the HW when I'm in abrupt structure, pinnacles, deep ledges, where the cone sounds off of bottom of very different depths. In that setting, a narrower cone (and on a fixed lower frequency if you want to fish deep, like 400+, which I seldom do), the GT51M may be a slightly better tool for the job (which is what I switch to when I do go deep). If you're fishing in the flats, even deep like 500-600 without structure, the HW is just fine on its own because the depth throughout the cone is similar. I think they both pick up feed on the bottom in that depth equally well. In the end I'd drill the hole (I did), but that's just me. I hope that helps, and good luck,
