If you want two units, why are you also considering the single 9 ?? No box needed for the Touch units. Just a cable between units to share the LSS transducer.

You can share a LSS transducer via Ethernet. The LSS box has two Ethernet ports. You can use the US2 with either model, just need the Lowrance adapter cable. If you got two 7's would you put both at the bow instead of a single 9 at the bow??????

The high school club I am familiar with has their own jon boats with electric motors. They use coolers with recirculating pumps for livewells. For larger waters, their parents and volunteers provide more sofisticated craft, but if not enough are available, they use the jon boats and just don't go as far. For BASS affiliated clubs, the kids are not allowed to run an outboard for a tournament.

You are BASS fishing????? 4/0 Octopus Hook with added weed guard and 5" Senko:

I use Gamakatsu Octopus hooks when I want the strongest hook for big fish in heavy cover and Owner Mosquito hooks when I can get by with slightly weaker for better hook penetration. They are shaped the same. I use 2/0 for finesse worm, 3/0 for Trick worms, and 4/0 for Senkos. My avatar is the 3/0 Gammy with a Trick worm.

The first issue of XPS Flurorcarbon was made by Toray, then they changed mfg or formula and it was terrible--broke easily. They actually removed it from their displays. Both were in the white box. I have a couple spools of the terrible stuff that I marked DEFFECTIVE The current version in the yellow box is good line. I have used all three versions, still have some of the first issue Toray made. Bass Pro buys stuff that costs the less due to high volume purchases. Whatever company gives them the best deal so they can make the most profit on their brand name is what they carry.

It should work fine for both map layers. You don't have the oldest version of the 597, that did not have HD in the model name. The current version is Navionics+ Preloaded and is a 16 GB card. It has all the maps for the US and Canada. I have the 2GB version of Navionics+ and have used it in my 798ci SI Combo. It was made on October 26, 2009. The 500 series units are similar with less features. The first 5 or 6 digits of the serial number is the day the unit was made--- Year/Month/Day To view the Sonar Charts layer you have to change the Chart Select to FishNChip. You won't have Sonar Charts when you buy that card, you select to download that map layer when you do an update. You have to register and do an update within 60 days of purchase or you loose the year of Freshest Data Updates that all new purchases include. My unit will read the Nautical Charts (Navionics maps) and Sonar Charts on my Hotmaps Platinum card which is 16 GB. Just won't read the Platinum features.

More stuff to ponder: The coverage specifications are usually at a sound strength that is -10 DB of what is it directly under the transducer. Some brands use another sound strength to advertise their coverage from pulse center. The actual coverage that the unit can detect is more at lesser strengths. Just need a common measurement to compare brand's coverage. The spec coverage of most 2D sonar units using 200 kHz is 20 degrees. As the depth increases, so does the coverage. 20 degrees is equal to 1/3 the depth. In 30' of water that coverage is 10' in diameter on the bottom. Everything within that 10' diameter and suspended higher in the water column in lesser coverage is combined into that very first vertical row of screen pixels. Units with 83 kHz 2D have a spec coverage of 60 degrees. That is equal to the depth. In 30' of water that coverage is 30' in diameter. If you imagine a traffic cone turned upside down as the "cone of coverage" all inside that cone from the bottom to the top of the cone is what is recorded on the first vertical row of pixels and then that row is moved to the left, becomes history, and a new vertical row is recorded. There is no left, right, forward, rearward or any other direction, just distance from the transducer. As the recorded vertical rows are moved to the left across the screen, they are older history until they scroll off the left side as the oldest history.

No, there are no "sides" with 2D sonar. You just indicated the RTS window REAL TIME SONAR. That is a wide view of what is being recorded on that very first vertical row of screen pixels. Vertical Flasher.

You think a bass is scared of this rig? If you throw this combination of 30# gold superline and chartreuse Senko in super clear water with smallmouth, you better be holding your rod firmly or the fish will take it away from you.

I use YELLOW superline, the fish don't care. Some of my yellow lines are striped with red lure dye to get some contrast for some lighting conditions. Ever head of the Alabama rig? All those wires leading to the baits don't scare the fish and those wires are not clear. If you need an excuse for not catching, you can blame the line color.

GOOD price, may can do better, send me a PM with the source you found.

It is in its second year of production (typical lifetime for electronics) and will be replaced by the new larger Helix models. End of model year clearance. There is a dealer that has the larger units on sale. The 999ci HD SI Combo for $899 and includes the remote control The 1199ci HD SI Combo for $1259 and includes the remote control. The 1199 has been selling out as fast as stock is replenished.

Navionics Sonar Charts Live and Humminbird Auto Charts Live does the contours as you navigate. This is Auto Charts Live overlayed on Sonar Charts: With Lowrance GoFree, you can do Sonar Charts live to a mobile device.

I use 30# or 40# superline mostly in high visibility yellow on my 2500 Shimanos. Those are 8# mono equivalent diameter. I use 20# yellow superline on my 1000 size reels---6# mono equivalent diameter. Anything less has very little shock strength. When I use a leader, it is 20# fluorocarbon. Shakey head presentations and wacky rigging in all water colors.

Do you really mean Down Scan or traditional 2D sonar?????? Traditional sonar has the inverted somewhat cone shaped sonar pulse. There is no "side". Everything within the coverage is recorded on the very first vertical row of screen pixels on the right side of the display no matter where in that coverage it is. That is the only current data. All to the left of it is history. When everything in a circle is recorded on a single vertical pixel row, there cannot be any "side". If a drop, fish, stump, creek, etc is not constantly being recorded on that first row of pixels, it is not within the sonar pulse coverage. If you want to save a GPS waypoint of a drop, you have to create it as soon as the depth change occurs. Or you move the position curser to the recorded depth change and create a waypoint. This is a small creek channel profile navigating perpendicular to it. When I took the screen shot, I was already past the creek a couple of boat lengths. You could create a waypoint on either side of the creek where the depth change occurs or at the bottom of it so you have the center marked. If you had Side Scan, you could see which side of the boat it was on if you are parallel or perpendicular with it:

If your units have the separate frequency settings, you can run one with 83 and 455 kHz and the other with 200 and 800 kHz so they don't cross talk. The same 2D freqencies can cross-talk if the transducers are on opposite ends of the boat when their sonar pulses overlap. 200/455 and 83/800 also. You will get 2D and DS at the same time with the HDI units.

Horse hocky!!! If the transom is actually the back of the boat and not recessed like some commercial netters use, the outboard cannot affect the transducer at all unless the motor is in reverse. Water has already passed over the transducer face before the prop affects it. With the boat moving forward, any disturbed water that the prop causes is rearward. Simple physics and common sense. This is where Tracker puts their transducers since 2012:

As long as the sonar pulse can be transmitted DOWN, that is all that matters with a craft that has an outboard. Which side makes no difference. Inboard type boats have to allow for the prop that is forward of the transom.

They will update it for you.

Do it before the warranty expires. Moisture is NOT good and is unusual. They are supposed to be water proof. Make sure you fully seat the memory card door so the gasket seals the slot. You could have a defective gasket--that is the sponge thingy on the door. It is sort of small and not as convenient as the larger units. I have removed and reinstalled that door on a display model many times. Just did a software update for one a couple of days ago at a Gander Mt. Have you done the recent software update? Some great features included with that.

GPS coordinates have nothing to do with mapping of any brand. They are a function of your GPS system. GPS is not mapping and mapping is not GPS. Northing and Westing are not common nautical GPS co-ordinates. Those are UTM format Most systems use one of these: DD.DDDD DD MM SS DD MM.MMM Use this converter to get the format you have your GPS set to: http://www.geolifeline.com/coordconverter.php If you can do EXCEL, you can do it all at one this way: http://www.earthpoint.us/BatchConvert.aspx

It is also whatever voltage is used to broadcast the SOUND pulse, not the unit power supply. I have not seen any specs that state that.

My second example is a 420 acre lake. I did not use any gasoline, it is electric-only. I just recorded some each trip there. It is still an on-going project. Until every square foot is recorded, the map will not be completely accurate. I save all my Tracks so I know where I need to collect data.
