Cool Structurescan ducer angle

Hi

Does anyone know how many degrees is the LLS1 ducer working with, it must be something close to 180°.

I have problems to find the right place to install it, it's an small RIB, 17 feet. If I install it skimmer I get shadows from the engine, if I install it under the hull I get shadow from the hull

In my boat there's no possibility to do a thru hull installation. Also I get interferences when I use the bilge pump and the point is that the bilge is installed right in the opposite


Any help will be appreciated, I'm very close to get crazy

Forgive my mistakes, its hard for me to write in something that looks like English

In advance

THANKS!

The 10dB point for the total coverage of StructureScan is about 148 degrees @ 455kHz and about 134 @ 800kHz according to what I've read.

At shorter distances the coverage will be a bit wider, and longer distances a bit narrower.

Not sure about the LSS-1 & how it might apply to your possible installations, but I believe for v-hulls & thru-hull T/Ds it is recommended to use 2 scanning T/D's to avoid hull-shadow blockage.

Thanks all you for the information, I was thinking to do a double ducer installation with a T but my wife does not agree

It is hard for me to explain in English, but I think I'm going to use an strong metal line that can be move up and down.

I'll move it down when I want to use it, it'll will not affect as the LSS1 has to be use anyway at low speed

Do you know what I mean? Do you think it'll work?

Thanks again

Jesus
