Whether you're a commercial fisherman or a serious angler, your fishfinder is one of your most important tools for nabbing a big haul. The problem is that many marine enthusiasts don't understand the technology well, so they may end up with devices that are either not powerful enough, or go well-beyond their needs, providing a lot of information they don't even use.
One of the main specifications to pay attention to when selecting a fishfinder for your vessel is the peak-to-peak output of the SONAR transmitter. This determines how detailed the devices readings are of both local fish populations as well as the terrain underneath the boat. Generally speaking, the deeper the water where you'll be fishing, the more power wattage you'll want, with 800 watts being a bare minimum for boaters who will be in small lakes or very close to the coast. If you're a deep sea fisherman, or you're trolling well beyond the shore, you'll want at least a 3,000 watt system.
The thing to keep in mind is that higher power sonar will give you both a more detailed image, as well as a faster readout of what is underneath your vessel. Low power systems tend to lag, so that you'll have less time to react and aim for areas with higher fish populations.
There are many other features of fishfinders that you should take into consideration, but the power of the sonar transmitter is certainly one of the most important.
