Technology in Overdrive – the GPS Revolution

Next weekend, when you pull up on a brush pile on your favorite reservoir, or head out into the middle of the Great Lakes to relocate an isolated couple of rocks, remember that it wasn’t always this easy. The GPS that we take for granted today wasn’t available years ago – we’re not talking the 1950s and 1960s, but rather as recently as the early 1990s. Indeed, as a February 1991 Bassmaster article by Matt Vincent pointed out, “the long-awaited Global Positioning System (GPS)….(is) expected to become fully operational this year…”

If this new technology worked as advertised, there would be no more triangulating of landmarks to find offshore structure and cover, no guesswork or long hours of idling looking for irregularities. The console-mounted compass would become a thing of the past. GPS would be a game-changer.

Some technology savvy-anglers had previously used Loran (LOng RAnge Navigation) units to guide them. Loran, developed around World War II, was terrestrial-based (unlike GPS, which is satellite-based) and that presented limitations. Weather and the effects of sunrise and sunset had negative impacts on its effectiveness. Indeed, Vincent noted that “experts predict that GPS could eventually make Loran obsolete.” Those predictions came to fruition in 2009 and 2010, when all US, Russian and Canadian signals were phased out, although it is still used elsewhere.LORAN C pic1 Technology in Overdrive – the GPS Revolution

It takes only two quotes from Vincent’s article to explain just how limited we were by Loran in 1991: The system had absolute accuracy “to within a quarter of a mile.” It had repeatable accuracy “advertised at 100 feet.” GPS, by contrast, was accurate “to within 50 feet – the first time, every time.”

At the time, price points were likely to be prohibitive for the average bass angler. Magellan suggested that their unit would sell for about $2,700. Humminbird was quoted as stating that they intended “to undersell the competition, adding that fishermen can expect to pay ‘somewhere in the neighborhood of $2,000” for one of its GPS units – a wealthy ‘neighborhood’ by most standards.

Vincent was once again prescient in his prediction that the prices would eventually drop. A quick look through Bassproshops.com today shows 27 different GPS models for sale, ranging from $199.99 (Lowrance Mark-4 Fishfinder/Chartplotter) up to $2,799.99 for top of the line models from both Humminbird and Lowrance. The latter include features that Vincent could only jokingly dream of two decades ago, like split screen displays, side-imaging, and mapping chips.

Today, even the casual weekend angler is likely to have GPS in his boat, in his tow vehicle and likely on his smartphone as well. Meanwhile, while none of the pre-1991 bass pros have offered to give up their technological advances, there’s plenty of grumbling about the new generation of anglers not paying their dues. “I’d like to see them compete with just a flasher and a topo map,” is an oft-heard refrain.

    Yeah I just got a GPS about 18 months ago….I fish the same stuff all the time and the lake nearest the house don’t even show up on the chip. Glad I only payed $200 for the whole thing….all the “pros” have this stuff and they bump’n boat rails on the bank..LOL

      What lake is that Jojo? Some chips have more lakes than others. Or you can update the chip sometimes. It’s not a catch-all solution but they sure are helpful.

    Lake Secession…Abbeville County SC 1460 acres impounded in the ’30′s. No conture lines on any map I’ve ever saw. Good lake Oct-Mar. Very crowed in the summer time. I have the “newest” chip and it will come in handy at Guntersville.
