Help with Fish Finder - Any one tried these ebay fish finders

Hello Friends

I am planning to buy a portable fish finder.

Any one tried the wireless fish finders, a lot of them are for sale in Ebay.

Wireless Sonar Fish Finder Portable Fishfinder Alarm a0 - eBay (item 230425952984 end time Jan-28-10 01:48:59 PST)

Are they useful? Will they really help to understand the depth and presence of fish?

I have a similar one. Mine's a humminbird. It works good casting from the shore or a boat.

Thanks TTFishon

I am kind of not liking that we have to keep changing tranducers once in 400 hours for Humminbird....

This ebay product seem to have a replacable battary.

Looking at the price difference between Humminbird and this product...

I am curious to know if this product works as advertised!

 

[TTFishon]

Yeah, it's a lot cheaper than mine. I bought mine used for 70 bucks and mine's kind of bulky to carry around. That one doesn't look nearly as bulky.

The transducer thing was a -1 for me also. I ended up getting one of those Fishing buddies. It works great when sitting still and not so great once you hit about 3-4mph due to the round plastic pole that starts moving around due to the water current.

I'd also be interested if anyone buys the ebay thing if its worth anything
