Fishfinders operate using a single frequency transducer, dual frequencies, multiple frequencies or a broadband CHIRP system. In general, higher frequencies give the finest detail resolution, the least background noise on your screen and the best view from a fast-moving boat, but don’t penetrate as deeply as lower frequencies. Shallow-water inland anglers generally choose higher frequencies of 200kHz, 400kHz or 800kHz. For maximum depth, use lower frequencies. We recommend 200kHz or higher (up to 800kHz) for water depths up to 200' and 80kHz or 50kHz for deeper waters.
Hockey tape was made for the ice, and even though hard-water anglers are looking for a different kind of score, they should always have a roll on hand. A few wraps around the butt and foregrip of any jigging rod immediately improves the hold and comfort, but hockey tape can be used on any ice tool. If you’ve ever had the cheap rubber handle cover disappear from your ice scooper, you know the feeling of metal freezing to a glove or the burning sting of touching it with your bare hand. A few wraps of hockey tape can easily fix that. Should your bibs or jacket get hooked or ripped, the hockey tape will keep a tear from getting worse until you can make a permanent repair.
For ice fishing enthusiasts one of the recommended and top rated fish finders is the Humminbird ICE-35 model. One of the most liked features on this device is the zoom flexibility. It allows you to zoom in not just to the bottom, but also zooming in for more details in any part you choose of the water column. The three color fiber optic display gives you a clear view of the readings. The extreme temperature LCD technology reports the lake bottom and automatically sets the flasher. Other features include dual frequency, maximum 200 depth capability and 800 watts peak-to-peak.
The power of a fishfinder—the strength of the “ping”—is expressed in watts RMS (root mean squared). Power is directly related to how well you see in silt-laden water, view down to greater depths, and successfully resolve separate targets and bottom structure. A 500-watt (RMS) fishfinder should have plenty of power for most coastal applications. Serious bluewater anglers should look for 1,000 watts or more. Inland lake fishermen can see the shallow bottom with only 200 watts.
The sound wave spreads as it gets further from the transducer. The wider the cone, the larger the coverage area, but the as the cone angle spreads, sensitivity diminishes. A 20-degree cone is considered a versatile angle for fishers who frequent different water depths. More advanced devices come with double and triple beams, ideal for scanning deep water depths.
Hand nets are held open by a hoop, and maybe on the end of a long stiff handle. They have been known since antiquity and may be used for sweeping up fish near the water surface like muskellunge and northern pike. When such a net is used by an angler to help land a fish it is known as a landing net. In the UK, hand-netting is the only legal way of catching glass eels and has been practised for thousands of years on the River Parrett and River Severn.
Our Depth Sounders are designed to mount flush in the dash of your boat. Our friendly user interface, automatic range & sensitivity and proprietary algorithms produce precise readings at speeds in excess of 60 MPH. Say goodbye to the days of not knowing the depth while running your boat on plane. Our Hand Held Depth Finders takes portable sonar systems to a whole new level. Get precise readings on the go with just a press of a button.
If I'm scouting a new area I won't know anything about what sort of structure is ahead until I paddle over it, blowing out any fish that may have been there. With this little guy, I could cast it to the spot, get a read on what's below and proceed. And, you have the luxury of retrieving it slowly to see bottom contours between you and that fishy spot. There have been a number of occasions when I've made numerous casts at a fishy looking location (without any luck), only to paddle over there and discover that it was 10" deep, nobody home.

WIRING: It's like Christmas lights … once you get a good power source you can really go crazy. I guess that's one of the reasons I've never added a power grid to one of my boats. Sure as I do, I'll have dash lights, bow/stern lights, and an 18" subwoofer (though a pair of 10's would probably work just as well). Once you are set up with a 12 volt system, anything that will connect on a go-boat will now connect in your row-boat. Those are scary possibilities indeed. You'll need to keep the battery stationary, as dry as possible, and make it easy to get at for removal and recharging. The easiest choice would be to mount it in the front hatch area. The battery is actually pretty small, so you won't need a lot of room.
Choosing the perfect fish finder for your requirement is hard with many features such as imaging, power and more. The main purpose of a fish finder is to catch more fish with the screen displaying the fish and underwater structure and physical objects. Other information such as water temperature and depth are common on the majority of devices with many high end fish finders providing much more.
Look for equipment that will work with multiple frequency: higher for better detail but not as successful in deep water; lower for depth but less detail on your viewing screen. Of course, if you fish only in shallow water, you’ll be happier with high-frequency output. For deep-water work and for commercial fishing, you may want to use a lower frequency.
Best of all though, the Helix 7 is a complete package, and includes underwater sonar transducer and all necessary mounting hardware for quick and easy installation on your boat. All you need to do is power up the device, toss the transducer in the water, and wait for sonar returns to start rolling in. Make every fishing expedition a trophy winner with the Humminbird Helix 7 CHIRP DI GPS G2 Fishfinder.
Referred to as a fishfinder, graph, sounder or recreational sonar, these products provide anglers with the ability to locate and target open-water baitfish, game fish and cover. This underwater-viewing advantage helped launch sportfishing markets like never before, as anglers were able to better understand depth contours, bottom composition and structure location, plus how fish related to this environment.
Depending on where you fish, sometimes the difference between finding a hot channel where you can always count on the fish to return during a certain time of day and absolutely nothing can be just a few feet. If you’ve ever fished for walleye, you know what it’s like to find those feeding channels or to have the days where you just can’t quite make it work.
