Garmin GSD 26, serious sonar w/ CHIRP
So now a CHIRP war is breaking out. This morning Garmin announced two new black box fishfinders: The GSD 24 appears to be a $700 redesign of its previous top-of-the-line digital box while the $2,000 GSD 26 is an obvious play for the truly serious fishing crowd. The GSD 26 features “Spread Spectrum” technology, which seems to be another name for the CHIRP support that Simrad announced as part of its new BSM-2 box in September. In fact, both Garmin and Simrad will be running demos of their advanced fishfinding over the next couple of days off Miami, and I’ll be taking a ride with each…
Getting the most performance out of the new fishfinding boxes from Garmin and Simrad requires the use of one or more of the Broadband transducers that Airmar has been developing over the last several years. Yesterday, Airmar issued its own press release catching up with the various models they offer and the various names manufacturers have chosen for their own methods of processing and displaying frequency modulated sonar pings. At any rate, the performance claims are significant, as you can read in those releases. You might also learn something from Bill Bishop’s CHIRP musings and there’s discussion about Garmin’s new boxes happening on the Hull Truth. I certainly expect to learn something about Broadband-based fishfinding over the next two days, though it may take a while to report (lots more going on!). And what about Raymarine and Furuno? They both offer high-end black box fishfinders already, and with some support for Airmar’s Broadband transducers, like the ability to select a specific though non-conventional ping frequency to target specific fish species. It seems likely that they too will join the full-on CHIRP battle eventually.
