Fish Finders/Echo Sounders

[Rob Ward]

Anyone know if you can have problems with false readings from these, i.e. depth in shallow or cold water?

[Renrag39]

You can get 'double bounce' readings in very shallow water, but never had any bad readings I could put down to temperature.

 

You could get a false bottom from a thermocline in very deep water though.

Just googled it and apparently you can in depths of four feet and under which explains what I was seeing.

 

So it's bugger all use on the Commercial where I was fishing for Perch yesterday

I have only had experience of sounders from a boat but know it is important to have the gain turned down as low as you can to get readings. Too high and you get spurious readings.

I've been toying with buying one of those Rob, which one did you get and is it any good ? (Apart from 4 feet and under obviously)

Couldn't comment at the minute as I've yet to use it on a water more than four feet deep

 

It comes with a decent rep though - chinese copy of the Smartcast available on Ebay. It works at a longer range and you can replace the battery in the transducer unlike the smartcast.

 

Search 'Lucky Fishfinder' on Ebay, I paid around £45 including delivery.
