Joseph on the Quickdraw community website, but a member. Currently, there are no maps available to share for Lake St. This circle represents the approximate area of the map that is scanned by each pass. When Garmin Quickdraw Contours records data, a colored circle surrounds the vessel icon. To share, the data is uploaded via a computer and the map is available within a day. The Garmin Quickdraw Contours mapping feature allows you to instantly create maps with contours and depth labels for any body of water. in the field - using Garmin - you will need to print-off a tide chart and manually change the offset ev 5-20minutes. Garmin Quickdraw: My understanding is that maps are drawn directly on the unit instantly and up to 75 hours of data can be saved on a 2GB card. In other words - use a tide graph as your lake offset.
The reson: the tide only changes so much during the shorter time frames and you want to match the offset to the current time. With both units - I would recommend saving using shorter time frames (5-10minutes around mid tides, and 15-20 around the highs/lows) - before changing the offsets and/or restarting the logging of the sounding transects. On the Garmin you set it on the unit as you go - with the Lowrance you apply it afterwards on short time segments when saved as sonar logs & uploaded afterwards. With Garmin & Lowrance you can set offests (originally designed to deal with fluctuating lake levels). When they get the bugs worked out of panoptix for the saltwater angler, it will be Garmin for the win,Ĭlick to expand.Both Garmin & Lowrance's mapping are pains in the you-know when it comes to tides, IMHO MAtt. It was a factor in my Garmin choice too, and I'm glad I have it. Uploading your personal maps of secret ling holes to the public community in the cloud just seems funny to me, so needless to say my stuff isn't up there. Also best to do your mapping when swell is low and wind waves are not hostile. You'd want to map a contiguous structure all in one episode, as tidal height differences would introduce some weird artifacts if you mapped places at different tidal heights. There is a learning curve to data entry on it. FWIW I think it is a tool mainly for bottom fishing habitat (lings esp) in my hands. While it probably isn't directly responsible for putting any more meat in my freezer, I do think it's helpful if you're a map detail guy, or just interested in over-thinking it on occasion. It's actually pretty kickass, and can really add some granular detail to complex bottom structure. 7 GPS Fishfinder with Chirp Traditional, ClearVu and SideVu Scanning Sonar Transducer and Built in Quickdraw. I've used it to map out some interesting reefs that I fish, where the detail is lacking on conventionally available charts (garmin's base map, navionics, noaa, etc). I've been playing around with QuickDraw for a couple years on my 7612xsv.
