A common question that you hear is “is there a site that one can go to for a profile to fit a GPS to the person and needs?” Generally you can go to any of the major manufacturers’ web sites and find comparison charts on their models. Most manufacturers have comparison functionality on their web sites that could help determine what to look for. It looks pretty basic, and you may have already determined what you are looking for, now you just need to find the right unit. First you must decide what type of unit are you looking for – automotive GPS systems, motorcycle GPS, marine GPS chartplotter or fishfinder, handheld GPS units? I especially like Garmin’s site for doing comparisons of features. There you can pick your interests (basic handhelds, mapping handhelds or on the side there is a link to geocaching). You can learn a lot from their site, and they have a wonderful comparison feature. This would be a terrific place to start. If you like geocaching there are also sites such as geocaching.com which teach you a lot and are a lot of fun. I generally like helping you find answers to your questions, but at the same time a feature which makes great sense to one person will sound like a waste of time and money to someone else, so you really need to do the final homework yourself to be sure you really find the GPS unit which suits your needs and that you will love for some time to come. I hope this helps to simplify things a little for you.
We got a call recently from someone wondering whether he would be able to use the existing transducer that came with his boat. That opened a conversation about compatibility. Not all brands of ducers will be compatible with all brands of GPS fishfinder combination. You really want to do your homework on that one to be sure that you have the correct match. Also, his old fishfinder was set into his boat, permanently affixed; and he wanted to be able to drop his new model into the same slot. We did the homework and found the GPS fishfinders that would meet all his criteria. That was an interesting exploration, but we found some great options that would fit perfectly. During that search it brought out the fact that, although some fishfinders will work permanently affixed to the boat, some will actually get much better reception and give you better screen visibility if they are on a swivel mount which gives clearance all around. These are all important things to consider when shopping for a replacement GPS fishfinder combo for your boat to give you the best fishing possible. Happy fishing, and I hope you catch the Big One!
For all you beginning boaters out there, you really might want to consider purchasing a chartplotter for your vessel. Garmin chartplotters like the Garmin GPSMAP series include marine cartography – preloaded with marine mapping software – and have GPS and WAAS capabilities so that you can not only see the rocks and shoals to avoid, but you can plot your best course to your destination. Also, with the use of the GPS/WAAS capabilities you can know with accuracy if you are beginning to venture off course. You can also save each course you plot to make finding your way back to that great getaway or fishing ground a cinch next time you want to return. Marine chart plotters are built rugged to be reliable, and are completely sealed with a waterproof casing, especially built to stand up to use in harsh saltwater environments.
What are Gimbals, and Why do I Need Them?
Gimbals are used in mounting systems, especially for marine vessels, which consist normally of two concentric rings mounted such that their axes are able to pivot at right angles from each other such that one swings freely within the other. They work much like a gyroscope and are used as a mount for equipment such as a compass or other nautical equipment (even stoves, lamps, etc). Gimbals operate in such a manner that objects are permitted to swing freely between them so that the object will remain suspended in a level manner regardless of any motion of their support. Gimbals are commonly used for sea-faring instruments so as to counteract the motion of the vessel.
There are several parts to a gimbal mount. Normally it is made of a set of rings, but sometimes is a ball and socket arrangement, attaching ultimately to a bracket which will support the equipment and another part which will attach to the vessel. In this case, we would use them to attach our GPS fishfinders and/or chartplotters as important and useful marine accessories.
In helping our new friend search for the best GPS chartplotter navigation for his enclosed wooden boat, we have discovered that the manufacturer’s descriptions do not always educate you on whether your unit will work in an enclosed area or not. We are finding that it is important to do more research and be sure that the unit can handle an external antenna before purchasing it. There are often situations where you do not want to navigate your boat from the fly bridge and would appreciate the comfort of navigating from within an enclosed cabin, so be sure your unit has that capability before purchasing the wrong GPS navigation system/chartplotter for you. It would be convenient if the manufacturers would include that in their descriptions, but that is not always the case.
Several GPS chartplotters have the capability of being used with or without an external antenna and should be reviewed with this in mind. Be sure to look for more than an internal antenna. An internal antenna is convenient as it is more compact and does not need to be set up separately; and although it will work quite well on many boats, it will not serve in all situations. Another thing to consider is purchasing a 2nd mounting station in order to easily switch back and forth between navigating either from the cabin or the fly bridge. Happy boating!
