How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

The combination, which Humminbird called LCR, for “liquid crystal recorder,” propelled the company to market dominance and kicked off the modern era of high-tech fishing.
Wire the fish finder direct to the battery (either the cranking battery or an auxiliary battery). Don`t take shortcuts and run the fish finder power wire into a block or switch panel. Wire your fish finder the right way and extend the Humminbird power wire directly to the battery using the correct type and gauge wire.
It is not recommended to run a FishFinder and transducer on a boat that is not in the water as you will not get any readings from the transducer.
This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat with a two part slow curing epoxy. The transom installation, which is the most widely used, places the transducer on the outside of the boat hull.
Numbers on a nautical chart are depth measurements.

Water depths are measured by soundings usually acquired by hydrographic surveys. The depths may be in either feet or fathoms (the chart will indicate which).

How do you know what size fish you might be seeing on your fish finder? In general, the thicker the fish arch, the bigger the fish is. The length of the fish arch can also give an indication of size, but you have to consider adjustments for water depth. The deeper the water, the smaller the return will be.
All screen sizes are fully networkable, including Ethernet, Bluetooth, NMEA 2000 and Wi-Fi, and offer models with multiple sonar technology options.
In general, you should be able to get years of life from your new fish finder battery. However, all batteries have a lifespan. We expect our ELB lithium ion battery to last approximately 2000-7000 cycles until they should be replaced.
Fish Finder Amp Draw

Ex: Garmin Striker 4 is listed as using a current draw of 0.23A @ 12V. In this case for a standard battery with 10ah you will get a runtime of 43.47 hours in a ideal scenario. However since batteries never run at perfect efficiency I would cut 20% off of that number for real world power hours.

Fishfinders and depth meters usually work on 12V and should therefore always be used with a 12V battery, so a blue Rebelcell AV lithium battery. Depending on the brand and type of fishfinder, the use of a 12V DC stabilizer can extend the operating time enormously.
Remember these recommendations. You should mount your transom-mount transducer parallel to the waterline. While the vessel is moving, the device should extend into the water 3.5 mm (0.125 in.) below a fiberglass hull or 10 mm (0.375 in.)
Others say fish can`t hear a transducer`s click because it is a much higher frequency than a fish is capable of hearing. According to, the idea that fish can hear your transducer is a myth that needs debunking.
Mount a transducer too low and it will have too much drag in the water causing disturbance resulting in a poor picture, or even the transducer being ripped off the boat. Mount it too high and it will be out of the water or shooting through air bubbles for a poor to nonexistent picture.
Testing should be performed with the boat in the water, however you can initially confirm basic operation with the boat trailered. Press POWER once to turn the unit on. There will be an audible chirp when any button is pressed to confirm the button press.
Ultrasound frequency used by a fish finder generally ranges from 15 kHz to 200 kHz. However, the majority of the conventional fish finders oriented for recreational craft utilize 50 kHz and 200 kHz.
As a rule of thumb, use frequencies below 140 kHz when fishing very deep water (over 1500 feet). Between 600 and 1500 feet, frequencies between 100 kHz and 160 kHz tend to work well. For anything 600 feet or shallower, you should use higher frequencies – over 160 kHz.
Fish finders are among the most powerful tools anglers have for catching more fish. High-end fish finders can give you information about bottom structure, can guide you to the best fishing spots, and, of course, can show you how and where fish are moving underwater.
We could go on and on about the differences between fish finders and depth finders, but the bottom line is this: fish finders are feature-dense and made to find fish. Depth finders are not – they`re made to tell you the water`s depth, nothing more.
The difference between a fish finder and a Sonar

While Fish Finders can detect echoes under the ship, Sonars can detect schools of fish all around the ship, making it one of the most efficient way to search for fish.

More and more boaters are using the electronic device they purchase for a fish finder also as a depth finder. This is because most fish finders provide the depth as an integral function of their operation. However you can still purchase electronic devices (depth finders) dedicated to pinging for depth.
The Humminbird Basemap is built into all APEX Series, SOLIX Series and GPS-equipped HELIX Series G2/G2N and newer models. Based on freshwater data from LakeMaster and NOAA, the most-trusted saltwater source, these accurate maps provide you with a clear view of underwater terrain.

Teleflex Incorporated of Limerick, Pennsylvania, noticed the company`s success, and in 1993 partnered with Techsonic to create the Humminbird WIDE series, what would become one of the most successful product launches in Techsonic history.

Can a HDS 5 Lowrance Fish Finder be interchanged with a original Lowrance X135 Fish finder, and will power and Transducer plug right into the original supplied power cords. Is the HDS 5 or HDS 5X the same size as the original X135 by Lowrance. I am wanting to install the HDS version into to the original Bow mounted location as the X135 has already been. I s this possible without cutting a slightly larger compartment to accomodate the HDS 5 unit
ANSWER : Hi, well I am sorry to be the bearer of bad news but those two are NOT interchangeable sorry. The “Drive Current & Voltage” for the Transducer are not the same at all, in fact i don’t even think that the “pin outs” are the same? but cannot remember off hand? Unless specifically indicated by the manufacturer, one cannot usually swap transducers among instruments, if one does/did do so, well indeed the transducer maybe damaged and or the output of the sounder maybe damaged as well?

These manufacturers actually make it so that none of their equipment is interchangeable, as they wish to maximize the profits you see, and if one could just swap things among models etc, then “They” would, in their mind anyway “loose out”

So you will simply have to cut a new hole and mount for you new transducer. make sure you mount it in the manufacturers recommended place, the Bow is fine, although I often recommend that it be central to the craft, but, sometimes this isn’t possible for varying reasons.

Sometimes if one must retro-fit a new transducer to an existing but different size etc site, then, it is best to “Fill” the old mounting hole(s) with a suitable material, and then re-drill and re-mount it all again.
