Technology is great but sometimes overwhelming. I used to pride myself on thoroughly researching something before buying and always feeling like I made an informed choice.
I don't know if it's because I am getting too old or if these gadgets are just becoming too complicated, but I just don't have the time or patience to read up on the latest and greatest anymore.

A colleague of mine just purchased a boat and asked me to pick out a sonar unit for him. He doesn't realize the depth of that request! I too am thinking about upgrading my 10 year old Lowrance. So, might be a good time to start researching what is out there.

So, what do we want? Well, I am going to assume that my friend would want the same thing as I would want (he makes more money than I so he can afford it), and, it will almost certainly be me that programs it so I may as well shop as if shopping for one.

I have always liked Lowrance - for both marine and on the road. If it wasn't for the lack of chart compatibility and versatility when I last shopped for a hand held, I would have bought the H20. Right now I own GPS76 CSx. I use it in conjunction with my Lowrance X-25 sonar; a unit I am also happy with - or was at the time. Price was an issue back then, so I want to upgrade to something better. At the time too, I decided that a handheld GPS would be the best all-around choice because I can use it for driving, boating, Geocaching etc. and I would only have to program one unit. But, I now appreciate the value of a larger screen in a chart plotter and even those dedicated driving/mapping unit seem to function better than a portable handheld. I've always liked the handhelds though for their versatility - being able to add waypoints and custom POIs from my PC etc. I haven't found (maybe haven't looked hard enough?) a chart plotter or other device that does that.
But, I think my friend wants a dual unit [chartplotter, not sonar only] and I do too, despite the fact that we both have good handhelds. So, that is my first question: Do chartplotters allow you to connect to a computer to upload waypoints from other devices? Do chartplotters also have memory cards (like my 76 CSx) so that I can program the maps rather than buy cards for them? This is important to me because I have almost ALL of the Garmin maps on DVD (yes, purchased and licenced). Are there units that take both pre-programmed SD cards as well as flash memory cards?
We recently acquired a new patrol boat for our detachment which came equipped with a Garmin 4208. Since I am the tech junkie of the bunch, the task of learning how to use this thing fell to me. Well, the manual is the size of the Criminal Code! I glanced under the dash to quickly ascertain if I can connect my laptop to this behemoth and upload maps/tracks/waypoints. What I saw looked more like a computer server room rather than a boat!

I decided I will learn how to use it over the slow season but my point is, I would like to have a unit(s) that is compatible with everything else around here since our work and play times often overlap.
If it's not possible to obtain this compatibility/versatility between the fixed boat units, our handhelds and laptops, then all bets are off and I'll look outside of Garmin. Humminbird was a four letter word when I bought my Lowrance, but they look like they have improved by leaps and bounds.

As another point of interest, I would like to learn a little about the difference in transducer frequencies, i.e. advantages and disadvantages. I am quite disappointed with how easily my Lowrance loses bottom signal at higher speeds on my personal boat. I thought it might have something to do with peak-to-power or the frequency of the transducer but I have had a few sources assure me it's the hull of my boat that impacts this the most. Still, I live in deep/murky waters now (I was in shallower, cleaner waters when I bought the unit) and I would like something that is more capable.

Price range? Under $1000

I know I have been long winded. Just my way of being thorough. Thanks a heap for reading to the end. All advice is greatly appreciated.

re: Transducers

I know that you've heard this before and often, but if the electronics are working properly, the transducer is mounted correctly, and adjusted properly, it will perform at its optimum.

I?ve been running a 4208 for 2 years now. The unit is operated via a very intuitive menu system. Arguably the best and easiest operator interface in the business. Don?t think I?ve spent more than 5 minutes looking thru the manual. ;)

There is no PC connection on the 4208. The interface to the outside world is via SD chip. No need for external maps on the 4208 since the unit comes pre-loaded with everything you need.

The depth of water and how you fish would determine the best transducer frequency for you. Generally speaking unless your fishing in deeper waters and or fish a lot of structure a 200kHZ would work.

The Garmin 4208 with the sounder module and transducer would be way over your budget. I?m by no means a Lowrance fan, but I have to recommend the Lowrance HDS for what you want to do. Go with the 200/83 KHZ transducer.
