Installed this last night (just the el-cheapo Elite 5x DSi) to see how it would go locally, despite looking very cheaply made, it performed well. I was under the impression these we're moreso for finding structure and NOT fish, but it showed fish very well, especially Tarakihi which really surprised me.
Here is a Wellington harbour wreck called the South Sea, it's a minesweeper than was rammed by the interisland ferry in 1942 and is intact apart from the superstructure which was removed during salvage atempts - you can clearly make out the hull. and where she's lying.
The South Sea:
Bow below, lying on it's side - loads of sediment to the hull sides.
The stern section from above.
The complete boat, shows alongside a traditional 2D sonar which shows little info on what it is.
Bait schooling over the rear of the hull. You can see how much sediment and debris has built up to the sides here due to tidal effects.
This is a kelp forest, amazing detail of individual stems and bases.
This is schooling Tarakihi.
The results from above!...
Great wee bit of kit and works very well next to traditional sonar, it showed fish more as actual size dots and lines not so much arches, also picked up thermoclines really well. Can't wait to get out and play with it again!
Peace of cake to install. There is very limited options on it, it does not even do traditional 2D sonar only the 3D stuff, there isn't even a gain adjustment! Pixel count is pretty good at 480 x 480. I'd like to try side scan, but for my fishing I thing this basic structure scan will be great - certainly won't replace my main unit, but looks to be invaluable running alongside it. I saw stuff today I never knew existed!
The small vertical specs you see are my other sounder running alongside and causing interference, much cleaner when turned off. I picked it up for $700, which is pretty good, I think Marine deals has them for $999?
Looks good on paper, it has a higher res screen at 640 x 480 pixels and more power but smaller screen. The Lowrance DSi does do water temp. Humminbird's have the most problematic transducers of any fish finder brand, that's one thing that put's me off them, mind you, Lowrance aint much better!
Yeah limited to about 75m Mullins, had no issues in up to 30m today. Have you dived the South Sea out of interest? Be a walk in the park for you, would love to see some underwater pics of it, was thinking of lowering the GoPro down on the burley bucket. Apparently a very intact hull dive.
Yeah, even with that beast HDS10 of yours, still limited to the 75m thing, such is the limits of ultra-high frequency Dave. I'm thinking of an HDS8 to run alongside the 750's already... never been a fan of Lowrance but yesterday changed my mind somewhat, I can see structure scan being very important for under 50m which is 80% of my fishing.
IMO nothing holds a candle to Garmin's charting as yet though, the bathmetry contour info is simply unbeatable and far more valuable than Navionics charting. Anyone wanna buy a new, used once Elite 5x DSI?!
Have not played with Chip yet Kaveman, but it's surely the way forward, have a mate in aussie with one hooked up to his Garmin who was getting a good bottom reading in well over 1000m incl, fish sign, even a 2kw tdx would likely struggle at that depth!
They run at 800khz and 455khz Catchelot, will post a pic later, the transducer of the structure scan is a very small cylinder, about the size of a Vivid Marker, very streamlined and kicks up no spray despite a deep mounting depth, looks flimsy as hell though so longevity is doubtable?!
One really interesting thing I found yesterday as that this unit would not pick up the burley bucket at all! It had no issue with fish under it, but could not pick up the 3kg lead and pot weight hanging straight down 3m off the bottom, sometimes on 455khz it would show as the thinnest hairline horizontal mark (you can JUST make it out in the bottom pic at 11.5m down). This does not concern me as who needs to see it - only the fish around it. Never seen this before.
I found yesterday that under 15m the 800khz gave best results, over that - the 455khz had better detail and penetration. Here's another pic of individual fish from yesterday.
this is my mates unit in action ,have seen it work in 70mtrs sweet as ,i been a furuno person myself but just now added the hds10 gen2 and i find the sonar picture and detail outstanding when on the hunt for fish
Yeah anything under 50 m and the ss delivers the goods in terms of detail. I can see single fish easy - made a big difference for me targetting snaps in the harbour. I may be wrong here but i think the hds units use a type of chirp system. I recall reading some techo guys talkin about it in the hull truth (i think). They even explained how it all works...pretty incredible stuff really.
Yeah, been through that one before and found that greater seperation between the ducers fixed it. Dunno why, as I thought the same - different frequencies should not have an effect on the other but for some reason it did....
