Kela,
You need to give some more detail as to the type of fishing you want to do and your budget.
Sounders range from a couple of hundred dollars to a couple of thousand.
cheers,
Owen
Whats the good brands? How much do they cost?

The whole world's mad save thee & me (but I'm not too sure about thee)
Ah ok, sorry mate...
Just starting out fishing, dont know to much about hot spots different types of sounders.
Probably looking at mainly fishing in saltwater bays/beaches etc... as for the sounders looking to spend between $500-$1000
Any help greatly appreciated...
Cheers
Have you got a BOAT?
If so what type and size?
Basic rule the better the power output of the transducer the better the sounder. ie playing around in the bay 300 watts rms is plenty, going out to the shelf 500-1000 watts rms, chasing Big Blue Marlin 1000-2000 watts and lots of money.
But 500-1000 will buy you easily what you need.
what do you mean by watts rms as power output of the transducer, i've never seen that before.
The transducer is the part that goes in the water normally at the back of a boat, a fish finder is a sonar just like ultra sound or those used by submarines. It send sound waves out in the water and listens to how long it takes for them to bounch back off an object. This gives distance to bottom or objects in between (hopefully fish, reef, wrecks, weed bank or sometimes just jellyfish) by the length of time it takes. The strength those waves are sent at is important as to how well the sounder will operate in different condition (freshwater has less resistance to sound waves than salt, and shallow water takes less power than deep). These sound wave strength is measured in watts (Watts is the unit of power consumed by something ie 60 watt light bulb is not as bright as a 100 watt light bulb because it does not use as much energy (power/electricity)) therefore the higher the wattage the stronger the sound wave the better the reflection (picture on the sounder).
RMS is a little more complicated (it's been a while since i went to college) as it has to do with maxinium wave time and power. There is another unit that gives actual time and power but with so many variables(water types, deeps, speeds etc.) manufactures use RMS (I think thats right?).
yeah got ya, it was late and i wasn't thinking RMS= Root Mean Square.
so i have seen it before just not thinking.
thanks
Someone told me to also look for vertical pixel resolution. For eg 128 vertical pixels in 128 metres of water = one pixel per one metre of water so it will only pick up fish 1 metre or bigger. Is this right or not anyone know?

Bruce.
