Recommendations for a Fishfinder? Dual frequency or not?

[Janos]

Well Martha, the much loved club rib, needs a new fish-finder. We can get a bog standard one for around £80 or £90, and a fancy dual-frequency with colour screen for around £300 to £400.

My question is: Are the fancier models worth it? And can anyone give any good recommendations.

Cheers,
Janos

We used to have Huminbird depth sounders on our boats but slowly they died. We now have Garmin 90, 120 and 140's and I am not impressed. They seem to pick up a lot more interference from the engines than the Huminbirds ever did and the picture of the bottom is not as clear.

For all the diving we do ie. drive to gps point, find wreck by depth sounder, drop shot. Then a standard depth finder works fine.....and there is so much more to spend the extra money on when you own a boat!
