    Anyone have this unit? Do you like it? I want side view. I already have a Garmin 7610 SXV. Want to up grade transducers.

    Thanks,

    I have a 7610xsv with the first generation GT51 Thru-Hull ducer. Should be the same quality as the transom mount model. I think the GT51 is more than sufficient for our local waters. You can spend a ton of cash for better quality transducers but this is heaps better than the B744 that I had prior. I only use the sidevu and downview looking for bait. Other than that, I don't mess with it. Maybe if I had a second screen I would have it on but I rather focus on fishing and chatting instead of staring at the my electronics.

    Looking for mackerals. You can see the bait on the port side with the sidevu.

    This image was taken in about 1200 feet depth with depth reading set at 300 feet. I didn't take a image with the side view but I'm sure it will capture an image of the bait to 150 feet. I think about 150' is the max depth for the sidevu then it just gets blurry.

    Al,

    Thanks for the reply and great detailed info. I appreciate it. The thru hull is what I prefer, but that faring blocks seems like such low quality plastic. Maybe I'm wrong.

    I didn't use the flaring block since I had a flat spot. Not sure if you have that option. 20160502_123708.jpg

    There was a flaring block before with a B744. I was lucky that it didn't get in the way of the trailer but I think it made the boat track a bit oddly.

    I'll see if I have the room. As you know, Parker doesn't leave you too much room in the bilge area.
