HD vs Compact transducer

[ctepps]

I apologize if I missed this being posted before. Is there any images floating around (possibly of the same area) that shows the difference in image quality between the two transducers.

[ezfishn]

Haven't seen any posted that show side by side of the same area. May be hard to find.

I'm just curious how much of a difference it makes. I'm sure that is a better transducer. Just wondering how much better.

I did a test using the two different transducers with one of my 1198's yesterday.

Disregard the stuff in the water column, that was due to the way I had the Compact SI mounted for the test.
Just pay attention to the bottom and trees/stumps. I tried to scan the same place each time which is a couple of trees in a creek channel going the same speed. The unit settings were the same.

HDSI:

AWESOME! Thanks for posting that Wayne.. A lot of people want to see the difference...

Glad I made the swap to HDSI

[jbryan2]

That is pretty awesome.

[ctepps]

Wow...I was really curious how much of a difference it could really make, but wow. Looks like a transducer upgrade will be in my future.

[deepanchor]

Impressive. Actually, both. However, HDSI just a lot more.

Wayne, were these set to 455 khz?

Wayne, were these set to 455 khz?

Yes, I don't use 800 kHz. It has less coverage.

Yes, I don't use 800 kHz. It has less coverage.

That's very interesting! I'm glad I asked. I had contacted HB recently and asked about doing this upgrade when I buy the Helix 7 SI G2N and was told they didn't believe it would make any difference because the Helix doesn't support 800 khz, but obviously it somehow improves the image quality even with the same 455 khz frequency. Hopefully the improvement is still there or even greater with the CHIRP frequencies.

Just put on the hdsi. It's much better. Except it loses bottom on plane no matter where I set it. Never had that problem with the compact transducer. You can't use a thru hull on a metal bottom correct?

Wllye, what head unit are you using?

I was quite disappointed in my HELIX 9 SI gen 1 until I bought the HD transducer. You won’t be sorry.

thanks

Bitchin' Wayne! Just plain Bitchin' ......

[Sparky123]

There is clearly a big differace. Is Onix any sharper?

Great Job Wayne ! (As usual)

I really think Humminbird should offer the HDSI transducer as a option / different model / on all Helix (compact Si) units.

If you got the cash upgrade to HD otherwise put it on the to do list. I really like mine.

[Ranger-85]

WOW ! Big Differance Glad I put the HD on .

[jcpanther]

Awesome pics.....that just confirms my choice!

[Ohio Archer]

Wayne, could you tell us what settings you had both the images set on? Would a different setting have made the Compact SI a bit clearer? I've been playing with the settings on my Helix 7 to try to get cleaner picture. Thanks.
