What research says

Here we look at the bigger competitors in the range of $940.00 to $1300.00 all units from the pros. We compare Garmin, Humminbird and Raymarine. This review was based on info from owners and some exciting fishing trips.

To begin, the build quality on all these fish finder units is solid with emphasis on the Garmin. Garmin's experience in creating mapping devices is clear here. The controls are intuitive and the Garmin GPSMAP 545s offers great features at a price-point lower than its competition. One of the cooler features is the alarm for fish size. This unit is a sounder and GPS utility with features for the constant angler. The biggest downside to this unit is proprietary software and connections. The 'you must use our products' approach is limiting.

Ranking in next is the $939.00 Raymarine Fishfind DS600x. This unit packs a puch with one of the most important features of any unit; A brilliant display. The Raymarine is very readable. The high resolution screen and lack of un-needed bells and whistles makes this unit a straight-up no brainer, and lets you concentrate of whats really important; fishing.

The last up in our comparison is the $1299.00 powerhouse from Humminbird. The build quality is superb, the features are over the top, and of course you can build it into the deck. This is a water tool that works for anything from Bluegill to Swordfish and from coasting to coast-lining. The most power of all the units we feature. GPS tied to a vast memory with track and chart plotting as well as speed. Dual beam and much, much more

In considering what to purchase, first consider how much you're going to be on the water, what the waterways around you are like and lastly how serious you are. If you go out once per week or more, the Humminbird might be singing your song. For the budget conscious the Garmin offers some heavy competition to the Humminbird at a price point just above Raymarine's offering.

I've used the Hummingbird and the Garmin and if I had to choose between them I'd go with the Hummingbird 957c Combo fish finder. I think they're both about the same quality, but Hummingbird is just easier to use.

Greg said:

I haven't used the other two fishfinders in the review, but I have to say I really like my Garmin. I got it from my wife for my birthday and it is the best gift I've ever received.

Florante Almario said:

Do your have a Used Fish Finder,1000 feet depth range with a transom mount dual frequency transducer?

Douglas said:

The best fish finder is Hummingbird in my opinion. You can factor in all the bullet points and everything, but what you can't factor in without years of using these products is the quality of the materials and how well it holds up over time. That's why I think Hummingbird makes the best fishfinders. But Garmin is good too.
