A friend brought this Humminbird Fish Finder 535 from a pro that can't be recommended on ebay. Why can't he be recommended? Because he told my friend that it could be configured to metric measures and it is not the case. And as there are only the brits who use feet and farenheit in europe he wants to get rid of it here. It has been used exactly 8 times and is as new.
Here are the spec
He's hoping to get 150€ (about £100) + postage (don't know how much that is) but price is negociable. My Dad could even pick it up and take it back to Weymouth at Christmas if you're interested.
