Author Topic:   Fishfinder vs Depth Sounder?

I have a depth sounder on the boat but decided to trade up and go for a fishfinder. I was wondering if there was any advantage to having both?

Thanks

The only advantage I could see is if they are located at different places and then only in very shallow water. They are both sonar devices, and if they are on the same or harmonic frequencies they will interfere with each other.

A so-called fish finder is a depth machine that displays targets between the boat and the bottom as well as bottom depth and character. No need or use for a depth-only instrument if you have a good fish finder.

As JB said, the fish finder should have all the features fo the sounder and more. I always thought the term "fish finder" was misleading, because in most cases, any debris or suspended objects will show as fish, but could be seaweed, or other items. Maybe some of the fancy newer units can decipher fish better but I still see anglers getting confused trying to read their color screens.

I am currently looking to buy this combo unit which combines fish finder with GPS chartplotter, so it can mark your good fishing holes and then give you water temperature and depth for accuracy.

It's been a while since I priced them, but last I recall, fishinders were actually cheaper than a regular old depth sounder unit. Personally, I have no real use for a fishfinder as opposed to a depth sounder, but I've found it to be a nice convenience to get a graphical display of the depth. Still, a simple depth sounder with a compact display would be preferable, were it not so expensive.

Steve,
If you have Garmin units you can hookup the GPS to the fishfinder and mark from either.

A quick search on ebay, looks like the depth sounder alone is much cheaper than a fishfinder.
