i'd say it comes down to if you want a digital (like the screen your using now to read this) or anolog (fixed blinking leds) sonar. the lx7 has 6 chart options and you can have up to 4 of them at one time.next major factor over looked is the lx7 has an optional troller or transom mount transducer so it is used year round.another option with the lx7 is tv out put.another with lx7 is can be upgraded into the lx9 that sports a camera so only ony screen to use for both camera and soanr.no noise from the lx7.so it comes down to what do you want from your sonar more than the few questions you have. it's kinda like buying a van or a truck. they both do about the same thing but in this case there are way more features in the lx7 hands down. being able to upgrade the firmware as you noticed is a major factor while vex has no option. it has been two years since marcum released a firmware update and yes one is iin the works for some bugs just like your computer has bugs so they work on them all of the time. the new firmware was due early this year, but they had poor ice conditions to make sure it is ready to be released. they are 150 thousands marcums in the field today and half of them are digital. there are no digital vex's in the field at all.the bug with marcum is 2.5 feet of water directly under the transducer is missing the jig. if that might be a problem you can't live with until their firmware update is released, then go vex.the other is if fishing 10 of water we use open water mode to reduce the echo return curve gain and then use ice mode deeper than that.both of these are in their firmware update and they do have them fixed, but it isn't released to the public until their field testers make sure there are no added bugs. it is very expensive to make their updates and they don't want us to beta test it.both sonars you have your mind set on will be fun to use. i out grew my hb ice-55 and i'm glad it broke down too. it forced me into looking closer at what is available today when i bought the lx7 and recently upgraded it into the lx9. there is nothing better to upgrade into and it is a fun unit to use and i won't be out growing it any time soon.also, marcum can add new features to the lx6, 7 and 9 besides tweaks. look at what their last update did for it's users to get an idea.their service is the best i have had and i have has the worst service and most expensive from hb.think of those things while shopping them.as far as moving forward, the lx7 is rather new. the company who started this type of sonar was aqua-vu and they made the showdown and is digital. marcum bought it and moved forward into the colored showdown if you will and those are the lx6, 7 and 9. recently rapala bought marcum because they know the importance of this sonar.the vex and marcum lx5 are about the closest to comparison in analog. so look at those if you want a spinning plastic hub with flashing lights and a loud motor noise.i have the best anlolg from hb and the best from marcum. you could buy both and use the one you like best.as you noticed there are no such sonar as "bullet proof", so this shouldn't be used as a selling point. there are reconditioned vex's for sale on vex's web site.i will say that the vex is the most simple unit to operate of the two. i use them too because i set one up for a buddy who doesn't understand them yet and his son took his showdown and left his vex with my buddy. i prefer advancement in sonar and options and features and hope vex will get onboard and have even more of these things to offer us so it's not just one company. really there is no competition to the lx6, 7 and 9.the other companies you didn't mention are open water units with added or exchanged transducers to be used on ice. so they have their own issues. their is lowarnce who doesn't stand behind their products from what i have read here and hb who is a sham and i hope they go belly up. i hope garmin gets stronger and they are trying. i do like garmin brand products, but they don't offer any thing close to the lx7 either.i hope this helps you in figuring out the two sonars (and then some).
Good handheld gps is the way to go for me. I dont need another battery sucking option running, maybe they could put an off button on it.
Yep, when is that RT9 coming live?
maybe get a deal on that display unit at gander. will come with 2 year warranty and if any thing is wrong or goes wrong marcum will have it back in your hands in less than 10 days.they are using it in the field testing it still and working with fcc on the gps is what marcum has said end of last year. they say they like it it a lot.the rt in the name rt9 stands for rugged or ruggedised tablet. not sure how it got the numeral so high on the 1st rt product.not helping with gps on my small lakes i fish meant i didn't need to wait for it while deciding to upgrade my lx7 to the lx9 or spend the 1600$ for the full version of the rt9. there is about a 400$ gap between the two at retail.
I posted on their Facebook page about the status, asking if it were going to be available soon. Response from Marcum was: "absolutely". Guess there is some ambiguity in that question and response. I sure hope to see it by early fall.
i mentioned the rt9 because you are worried some thing else will come out as soon as you buy a new unit that is the latest version. you can't buy the rt9 right now is all, but i wanted you to know the answer as far as marcum and what they have in the works.the lx7 will be fine and if you like it enough and want a camera too, then you upgrade it. here's my findings when i did just that;http://www.iceshanty.com/ice_fishing/index.php?topic=320114.0here's a section dedicated to only marcum as they are a site sponsor here and none of the others are and that should tell you some thing about them;http://www.iceshanty.com/ice_fishing/index.php?board=179.0it is their off season and they do like to talk about fishing, so give them a call. they should be happy to talk about it.888-778-1208
nice! happy late birthday!she's a "keeper".they are for open water too, so you don't have to wait for ice.
