Your lesson is private to you and your guest(s). This on the water class focuses on the very basic fundamentals of SONAR as it applies to common Fish-Finders used by the everyday fresh/saltwater angler. It is presented in a laid back, easy to understand, format designed to simplify the complex and often misunderstood science of SONAR technology and its related equipment.
This lesson was developed to give you accurate knowledge so you may correctly advance your own skills as a SONAR/Fish-Finder operator and aid you more accurately understand and interpret what you see on your screen. The science information presented in this class applies to ALL BRANDS of common Fish-Finders.
Currently, common Fish-Finders DO NOT accurately answer the following:
How deep are the fish?
How big are the fish?
What species are the fish?
What direction are the fish heading?
The answers to the above questions are guessed at by the operator based upon what he/she sees on their display. The accuracy of the guess can vary greatly depending upon the knowledge, skill, and experience of the SONAR operator.
There are no, “One size fits all settings.”
Unit settings are probably the most frustrating and confusing idea for most Fish-Finder owners to deal with. That is because there really are no “Best” overall settings. In order to increase success, the operator must first have a general understanding of the science of SONAR and related equipment. This is so he/she may apply the appropriate unit settings for the target environment and for his/her style of fishing, such as, trolling, cast retrieve, drop fish, etc. . . Unit settings may need to be adjusted several times during the fishing day in order to maximize the accuracy of the information desired.

*NOTICE* – Boating and fishing may require modest to strenuous physical exertion, dexterity, and endurance. Maintaining one’s balance, hanging onto railings during moderate to heavy seas, or just hauling in large fish can be tiring. It is your responsibility to ensure you possess suitable physical fitness to comfortably manage the aforementioned. If in doubt, please seek the appropriate medical advice of a qualified physician before purchasing our services or boarding our boats.
We have aboard our vessels (boats) a large variety of fishing gear and tackle, such as, hooks, rod holders, rod racks, sharp implements, sharp knives, braided fishing line, and the like. Also, some of our fishing tackle, such as jig heads, sinkers, divers, and the like may contain lead. When employing common sense and sound safety habits, these items are very safe. However, when improperly handled or used, these items may cause serious bodily injury and/or death. Following your Captain’s instructions will greatly minimize risks and allow for a fun filled experience.
Persons failing to wear a US Coast Guard (USCG) approved Personal Flotation Device (PFD aka “life jacket”), while aboard any boat, have a greater risk of drowning than those who wear PFD’s, especially persons with little or no swimming abilities. Although the US Coast Guard only requires approved PFD’s be worn aboard boats by persons under the age of 13, we highly encourage all of our clients wear a PFD while aboard any vessel. We will provide our clients with USCG approved PFD’s to wear on our boats if they desire. If preferred, clients may bring their own USCG approved PFD. It will be the client’s responsibility to inspect their own PFD to ensure it is USCG approved and is safe to wear. The Captain however, will inspect ALL PFD’s to be worn by persons under the age of 18 to ensure they are safe and USCG compliant. If they are deemed unsafe or not compliant by the Captain, the child will be required to use our PFDs. Adult clients electing not to wear a PFD will do so at their own risk. A situation may arise where the Captain may require everyone aboard to wear a PFD.
