But if I had one the fish would get a break because I'd be playing with my Down Scan and not fishing.

The HB view looks to be misadjusted to make the LEI look a lot superior. Here is a down image that I did with my HB 798 recently without any tinkering with the settings.

Yea I'd say that HB shot needs a little adjustment. I've seen them produce some better images than that. However, from what I've read pretty much across the internet land the Lowrance does seem to have better quality to it both sideways and down.

I'm not 100% sure, but isn't the HB downscan image produced by a combination of side scan images and makes up for the gap below the boat with software? Where as the Lowrance downscan images are actually generated by a third, seperate downscan trandsducer?

Either way... great pictures.. both these units will / have changed everything and make it almost too easy for the average angler to find structure. You still have to catch the fish though. Grin

I'm excited to see one in person sometime.

I doubt anyone is intentionally "mis adjusting" shots to make one brand look better. I would bet that most of the shots being compared are beta versions of the bird downscan software. I've been waiting to see more pics of the release version.

Your pic is pretty good wayne, congrats!

Yeah, the lowrance shot is done via an independent module. HB did it first and has been doing imaging for a while now, so its an older technology. Lowrance has just released a current/complex (costly) system, so in all fairness I would expect elements of the system to be better.

I've heard rumors of HB doing a possible release of a independent downscan/side scan module, but I suspect the outcome of the current lawsuit will dictate tons.

He actually has both Lowrance and HB units running side by side. Not sure why you would ever waste the money on doing that but its what he claims.

The Humminbird version of Down Imaging was just released on Feb 12th and 14th, 2010. There never has been a "gap" in the bottom coverage of the left and right SI beams. The beam coverage and the 2D sonar cone coverages are based on a certain decible strength and additional actual coverage range is experienced in all systems in other decible ranges. Just the strongest signals are represented in the published coverage angles of SI, DI 2D, SS and DS. With the Humminbird SI, the left and right beams actually overlap directly below the transducer and that overlap is part of the DI image. It is real easy to determine the overlap is occurring since an object is shown on both side images when passing directly over it. I haven't had my SI unit very long and have seen that overlap lots of times when passing over submerged objects.
The Lowrance Structure Scan transducer uses three narrow beam crystals (left, right, down) and the Humminbird Side Image transducer uses two narrow beam crystals (left, and right) and also a 2D cone crystal with only the left and right being used for Side Imaging and Down Imaging.
If you want to see what an experienced operator of the Humminbird system can produce, check out the images that TritonMike has posted on several web sites including Bass Boat Central, and Yahoo SI Groups.
I seems that some comparison posts are agenda motivated rather than showing how each system can perform at it's best.

If that guy is running that HB unit to the best of his ability he wasted his money or needs to read the instructions. HB produces a way better pic than that. I know from experience, not just looking at pics.

Than you boys post up! I'm ready to see some better pics than what has been posted above or across the net as a whole. I've always thought the side imaging concept is quite amazing!

Yea, lets see those photos. I intend to buy an SI unit soon. I have been on 5 or 6 sites in the past few days reading up on HB and Lowrance. Everyone on those sites say that HB is better than the pics posted but no one has posted any pics that are better than the Lowrance.

Not sure how posting this link is going to work, I'm a little new here...

Anyways, good example of a scientific method regarding the capabilities of HB's downscan. A seven inch target identified in every viewing mode of the HB. Considering we'd all like to be catching bass bigger than seven inches, I'd say we're all good.

If you'd like to see much better images Kenny, check out the image galleries on the sideimagingsoft forum. Very impressive.
