Is this overdone or does it make sense?

Coastal waters, 10-40 metres depth
Mostly Cod and Seabass fishing on flats and wrecks.

Pictures are from lbs1 (bsm-1) and p79

Si from lss2

Hmm, 50 views but silence all over the place.
Nobody?

Great pictures but I'm not what you mean by your question "Is this overdone"

abielecki

Ah - I missed that. You look to be correct.

I would think that for these depths and type of fishing, upgrading the transducer would be sufficient. Not sure which display is being used (probably NSS/NSE) but going to a larger one is always better too. I'm no expert though.

keizerh

Yes it is about an upgrade
Screens are nso17 and nse12

Experts please advise

From the startpost.

Targets from bottom to 3 metres below surface

More detail in the view would be better.

OK, now that we have some understanding of what you're asking...

The BSM-2, when coupled with an appropriate transducer, will surely give you the additional detail you're looking for. But the M265 may or may not be that "appropriate transducer". We'd need to know more about your boat to be sure; but I suspect that the B175L/B175H combo might be the better choice.

Note that either way, this is a semi-expensive proposition. If you aren't sure about the return you can expect on that investment, you might start by simply upgrading the transducer you're currently using with the BSM-1. The P79 you're using now is not letting the sounder do anywhere near its best work. Look particularly at the B164 and the SS264W/N sets.

Return will be more happyness, unpayable
Boat is a Cygnus Tornado 26 foot deep v with yamaha straight six diesel with duoprop sterndrive
Hull is polyester
Bottomthickness 4-5 cm neer the keel no enclosed airbubbles
Barnacle growth is heavy
Boat sits in the water the whole season

Wil a chirp transducer work on lbs-1?

keizerh

So it is not a route, but a choice.
To chirp or not to chirp

Well, there's no arguing with that!


Not that it really matters, but are you sure about that last bit? Two inches of glass on a boat that size is well beyond overkill; it's downright silly.


This is going to be a problem regardless of what sounder/transducer you use. You NEED to keep the bottom clean for good performance -- and not just from your sounder.


I don't know the situation in your area; but typically, in high-fouling areas, there is a robust little cottage industry of folks who scrub bottoms in situ for a nominal fee. We don't have such a severe problem where I boat; but I've heard that in some places, some folks get this done as often as weekly. It not an expense I'd be thrilled about committing to; but OTOH, it's cheaper than hauling and scraping every month or two.

Also, if you use the right sort of bottom paint (a fast ablative) and actually USE the boat regularly (as opposed to just letting it sit in a slip), the fouling problem should be minimized, if not eliminated.


Not well, if at all.

keizerh

Keel is rounded off and thickness is the size i said. Width at that place is only 40 cm
Then i get big stringers
On the outside of them the hull is 1.5 cm, but there the surface is dry at high speeds

There is copper antifoul on the bottom, not good for through hull ducers
Non stick on the drive

No cottage industry here, 20 cm view in the harbourwater and temps well below 15 degrees before fouling stops

Can't always boat, have to work as well, to get some hobby money.

You both share the same vision, so I'll follow.

Either tru hull if it can handle Hempel Combic antifoul or M260 broadband in the hull in front of the engine

keizerh

Then I better sell the boat
Stop all hobby's and sit on my money till I die

I am just looking for a better view and most important for fishviews at places where i see no fish now. In order to catch something different

Itteldoo

That should be more than enough room to mount a transducer, as long as you can get to it.


Are you talking about conventional anti-fouling paint (such as a hard epoxy, like Petit Unepoxy Plus or Interlux Ultra), which uses cuprous oxide as an AF agent? Or something like CopperCoat http://coppercoat.com/, which essentially sheaths the hull in raw copper?

Either way, but especially with the former, I would not expect that to be a major problem vis-a-vis through-hull transducers, particularly if you stick to ones of stainless steel construction (such as the SS264 series).


I could find no reference to "Combic" on the Hempel product page http://www.hempel.com/en/marine/unde...uling/products; but nonetheless, I think you'll probably be just fine with a through-hull.

keizerh

Semperfihishing,

I do it for the view and not only to catch more of the same fish.
Cod is difficult on catch and release, so I just catch that much that fits in the pan.
Cost is not the (main) issue, the boat burns money anyhow.

But when 2 wise men say BSM-2/M265 or 175 chirp is overdone, then I stick to the BSM-1, and go out a few more times this year.

Itteldoo,
When the copper won't be an issue then I go for the SS264's instead of the M260 as soon as the boat goes out of the water for an antifouling job and sterndrive oilchange.

Thank you guy's!

There is no such things as "Overkill" :-)
The first two pictures are the Lowrance HDS-12 touch run CHIRp with the Simrad BSM-2.
The rest of the pictures are NSE-12 and BSM-2.
The transducers used here is the Airmar B175L, and B175M.


Shallow water performance is pretty sick.

keizerh

Nice pictures

Think I won't cut off my road and go for chirp transducer(s) with external diplexer(s)
