Perry's bass was a dink compare to this one:

Zoom finesse and Trick worms, no other comes even close.

Definitely get traditional sonar at a minimum.

What about the lake in Honduras that had bass in the 30# class that were captured spear fishing and there was an underwater video of some of them? Glen Lau may have been the one that did the video. I think the lake is Yojoa

The coverage of traditional sonar and its sonar pulse shape just shows something is "down there". The imaging technology shows fine detail with its very small coverage. It is basically useless for vertical presentations when motionless. Takes movement to scan to create the images. Having traditional sonar and imaging technology gives you the technology to interpret what each displays. Gotta have both This is both:

The Striker has 2D and ClearVu (aka DownVu). DV in the model name means DownVu. The Lowrance DSI units have Down Scan only and are OK paired with a 2D-only unit, but not much by themselves (actually quite ignorant marketing).

Yep, watched show and a few others during that time period. Flying Fisherman--Gadabout Gaddis

I have a bunch of them. Bought all of a store's stock when the bait was discontinued.

There is a spacer to go under the RAM mount for the wires. http://www.rammount.com/part/RAP-403U

Did not know that any Navionics maps are loaded to the unit's memory. You can see the Navionics maps on their website's Web App. They are current as of yesterday.

First thing first, the transducer is not a video camera and the display is not a video monitor A traditional sonar pulse (sound) is a somewhat inverted cone shape. The deeper the water is, the larger the area it covers. An imaging pulse is very thin front to back and wide to the sides, think CAT scan like hospitals use. Garmin DownVu and 2D sonar are "aimed" directly downward. ClearVu that replaced it is oriented a little forward to try to get by the lawsuit for using a downward oriented imaging pulse. For practical purposes both look straight down. I don't not know what the rated coverages are for Garmin transducers, but I can explain what Humminbirds are and you can get an idea. Garmin uses 200 and 77 kHz and ? pulse strength loss rating. The 200 kHz 2D sonar pulse is rated at 20 degrees of coverage which is 1/3 the depth. That means in 30' of water, the bottom coverage is a 10' diameter circle--that is not an absolute, just a general idea. The 83 kHz 2D sonar pulse is rated at 60 degrees of coverage which is equal to the depth. That means in 30' of water, the bottom coverage is a 30' diameter circle. The coverages are based on the sound strength loss of -10 db from the center. No matter what brand you have that has a LCD display, the sonar data is recorded one vertical screen pixel row at a time on the very right side of the screen. Then that row is moved left as history and the next vertical row records the sonar data, etc. The data stays on the screen unit it scrolls off the left side. Newest data is on the right side and oldest data is on the left side. So when a sonar pulse is recorded, everything within that inverted cone is recorded on that single vertical row of screen pixels. There is no left/right/front/back. Everything within the sonar pulse will be recorded as long as it stays within that sonar pulse. What you see recorded can be anywhere and any direction, you will just know it's "down there". For the depth readout, the very center of the pulse is used to calculate the depth (which is distance from the transducer) since that is where the strongest part of the sonar pulse is and where the bottom is closest to the transducer. Humminbird's Down Imaging pulse is 74 degrees wide and just a few inches from front to back. Don't know what Garmin's is, but is pretty thin since it does do just as good as HB. With that wide coverage, everything is still recorded one vertical pixel row at a time. Since you will have both technologies, you can use the DownVu to let you know something is directly below the transducer from left to right (thin coverage forward and rearward), just have to guess using 2D sonar.

I have done lots more since. Only when the track map has the lake solid red will the whole contour map be completely accurate.

Looks like Brushy Fork has generated enough interest that someone has done sonar logs in that area to add to the Sonar Charts map layer.

This is a Google Earth track map of some of my early recordings at Hunting Run:

I don't know if a Hook is compatible with Insight Genesis which is a Lowrance shared mapping product. I don't keep up with the "off brands" much. I did see there is/will be a new HDS unit update that will do Navionics Sonar Charts Live, but that is still shared mapping and the processed data is loaded to a Navionics map card. Three of my Humminbird units have Auto Chart Live built-in. That software creates HD contour mapping in the unit's memory or to a Auto Chart Zero Line card, and is not shared. That software creates contour mapping that is cumulative--the more you do, the more total data you have. Any other map creation software is the same, you keep adding data until all the lake bottom is surveyed. I uploaded my Hunting Run sonar logs to the Navionics Sonar Charts map server to get that data processed FREE. It is FREE for anyone to view or download to their mobile device or Sonar Charts compatible map card. I have all those recordings and can load them to the commercial Auto Chart or Auto Chart Pro computer software and have a private Lakemaster HD map for there if I want. Still takes the purchase of the computer software though. I certainly am not going to spend the time to cover the whole lake again to have Auto Chart Live mapping on any of my units. I have done some test passes with Auto Chart Live to see what it does. I did not pass over every square foot of terrain so the Sonar Charts map has just as much interpolation as if any map company would have since no company collects data for every square foot. You won't either if you do it. The colored areas are Auto Chart Live overlayed on the Navionics Sonar Charts map of Hunting Run:

Yes, some Humminbird units have built-in Auto Chart Live that does real time contour mapping to the unit's memory or to a map card with shorelines. It functions like Lakemaster mapping once created. No unit model has been mentioned in this thread to determine if it might have that feature. The Navionics Sonar Charts is shared and Auto Chart is not. Only Sonar Charts added to a Navionics Hotmaps Platinum card would have satellite overlay.

Yes, you do the EXPORT function in the waypoint menu. Load them to HumminbirdPC also.

Lake Pro is mapping in the unit's memory. Some higher end Lowrance units have Insight mapping built-in. The "Global Chart" refers to contour maps by Navionics or Jeppenen-C-map for foreign waters. You would get those by purchasing their map cards. Do not know what the coverage of Lake Pro or Insight is, but if you want more than what you get, you have to add another map product and it isn't free. If you want the Hunting Run HD contour map I did, you only have one choice, Navionics Sonar Charts.

You can view the current maps for Navionics on their website's Web App--both map layers. You can also turn on the Satellite Overlay as see what is covered, select Menu, then Map Options, and click on Satellite. Some of the canals do have Navionics Sonar Charts contours. What you see on the Web App is what you could have on the Hotmaps Platinum South card. Someone with the Lakemaster Pro Southeast card would have to comment about that product.

Any map card can be used to activate a Navionics Update card so the Update card becomes the Navionics+ version. The Update card is $99 MSRP. A direct purchase of a Navionics+ card is $199. You end up with two functioning map cards, the old one and the new one. Just cannot use the old card again to activate another Update card.

The Navionics Web App has the current maps. Any Navionics map card when updated will have the exact same maps. A new purchase of any Navionics map card includes a year of Freshest Data Updates. If you buy one today and register/update it today, you will have maps current as of today.

I typed one dash three and ended up with ***

Your indecision is based on myth. The salted or unsalted sink, neither float. Ones with a lot of oil on them will stay on the surface by themselves due to surface tension if placed gently, but will sink if submerged and will not return to the surface. The ones with the most salt will sink faster---that's it. Either does the same on a shakey head. It looks like the worm floats because of the lead weight and hook falls faster than plastic. Let it sit still and it will fall over.

What the hell, one to three using numbers was censored ????????????????????
