What is everyone using?

During the course of unpacking after a move I just unpacked a Humminbird HDR600 I purchased for a former stinkpot I owned. I am curious if anyone else is using this model and if there is any reason I should not put it on my Catalina 25.

If you are using this model or a similar one where did you mount the head?

I'm very pleased with my cheap LCD fishfinder.

I'm still using the Standard Horizen bulkhead mounted DL series depthfinder that was installed by the dealer when I bought my boat back in '83. The matching knotmeter gave up about four years ago and I replaced it with the newer model Standard Horizen DL series with the touchpad controls and had to enlarge the hole in the hull to accept the slightly wider paddle wheel.

Raytheon ST-40 Bi-data Speed/Depth.

IMHO If you're going to go cruising, you'll want features like anchor watch, shallow/deep alarms, logging etc. For general use and keeping water under the keel the 'fishfinders' work quite well.

I have a Garmin 168 GPS/Sounder, on a swing mount in the companionway. I like this unit because it gives me all the navigation data I need in one instrument and it was relatively affordable at $478.00. I had it's predecessor, the Garmin 125, on my old boat. Now that I have a non-retractable keel, I pay even closer attention to the depth sounder, since I can't just crank the keel up if I run aground! I would have liked to get the Garmin model GPS/Sounder that's the next level up, the model 128 or 188, but it was beyond my budget at almost $1000. It has a larger display screen, much larger memory, and takes the BlueChart ROM cards.

Hey Larry,
Does your compass change any as you swing around your radio/depthsounder setup?

I'm planning on installing a compass (Plastime Contest 101-which I got for Christmas-yes, I know, its French) on the port bulkhead, and was wondering if my radio, and instruments, which is on my starbord bulkhead, would interfere with the compass.

I tried to separate my steering compass from my 12V distribution panel as much as practical. I ended up mounting the compass above the galley, as my electrical distribution panel is now on stbd just aft of settee. Here' a list of some electromagnetic influences I wouldn't worry alot about:

Instruments -- Not likely to be a factor unless they contain permanent magnets and/or draw steady high currents.

Depth sounder -- These do involve high currents pulses, but the duty cycle is so low that the average magnetic field strength is a tiny fraction of what the power specs might seem to imply at first glance.

Two-way radio -- In transmit mode, they do draw a lot of power, but how often is that? A larger concern would be the permanent magnet in the built-in speaker.

Stereo, and other, loudspeakers -- Now these do contain significant permanent magnets, and so should be kept away from compasses. As I recall from high school physics, magnetic field strength vs. distance follows the inverse square law, so the effects drop off steeply as the speaker gets further from the compass.

Welcome aboard!

Wherever you end up mounting your depth sounder, it is good practice to develop a deviation chart for your compass. I have two charts, one with all electrics and electronics running and the motor switched off, the other with the boat running on motor. There may come a time when your electronics fail you, and you will want to know how much your ship's compass is "off" by when navigating. Any good book on navigation should have a basic deviation chart you can copy and fill out. I just pointed my boat to 36 compass points and compared the compass reading at each point with the GPS compass. The difference is the deviation. There are other ways to do it using charts and bearings, but GPS is the simplest. (eg. compass reading 090; GPS reading 086; deviation 4 degrees east). Note that compass deviation changes depending on the heading of the boat. It makes for a fun afternoon when there is not much wind around. And it's a nice way to introduce the grandchildren (in my case) to the vagaries of navigation.

I remember on our '79 C22 I mounted the compass in the center of a spare lower hatchboard - right over the keel winch! We had some interesting night navigation errors until we realized that that big lump of iron had caused a 20 degree "deviation"

Good points all.

I originally posted this question hoping someone was using this Humminbird model HDR600. It comes with a transom mounted transducer that ppears very similar to te accessory puck transducer. On page 3 of the online owner's manual (http://www.humminbird.com/development/images/PDF/hdr600.pdf) it states that this transducer may be used on a sailboat. They include the caveat that it might not work. They also offer a transducer exchange for this transducer for a puck transducer. You cannot try the one and then exchange it for the other. The main thing they warn about with the original transducer is a wooden hull which we do not have.

Anyone have any words of wisdom?

Thanks!

I've epoxied puck transducers to the inside of a solid fiberglass hull (like a C25) with good results before. Other folks epoxy a piece of 3" plastic pipe to the hull and 'float' the transducer in mineral oil..

Both work... main thing with the epoxy is to not get bubbles under the puck.

Sorry folks,
I really didn't mean to inject any politics into the discussion, or stir things up by making a comment about my Plastimo compass.

I'll be more careful in the future

When I do secure the puck, where exactly is the optimum location?

"where exactly is the optimum location?"

Very much a matter of opinion here... an area of the hull that stays in the water and has smooth flow. Mine matches the location of the sink/icebox thru-hull, except it's on the starboard side of the boat. Others prefer the aftmost sections of the area open to access under the V-berth.

If your boat's in the water you can test before gluing it down by usng some Vaseline to form a 'bed' for the puck (not too much). Important factor is that the puck can transfer it's energy (the ping) to the hull... and receive the return echo.

I've have very good luck with my pipe/oil assembly mounted under the drawer under the sink. It was a little tight getting to, but I think you could also get to it through the aft birth storage. Except when my bottom has been too dirty - which seems to have some effect - it works great.

One caveat: When I got Orion the PO had a fishfinder, sounder with transom-type transducer glued to bottom just aft of keel housing (SK)and all worked OK. With subsequent bottom jobs the unit ceased to read anything, although it would power up and self-test OK. I sent unit in for repair, nothing wrong. Conclusion: change in bottom paint prevented transmission, I had heard of this but never observed it. Now I need to rig a transom-type transducer to get it working agin, or remove bottom paint under the sender. Since I do not trailer, and haulout around here is quite expensive, looks like a transom transducer to me (Oh well, as Roseanna used to say) Ron srsk Orion SW FL

Hi Ron,

That's interesting ... do you happen to remember what brand/type of bottom paint you used? Did you also put on an epoxy barrier coat?

I've never read about this before ... it'll be interesting to see if this has happened to anyone else.

Thanks for help ... 'hope you get yours fixed!

In a past post, I did say that my name is pronounced in a variety of ways including Loo-sure, Loo-see-ay, Loose-ear, Loo-see-er...and I pretty much answer to all them. The most common Americanized pronounciation, Loo-seer, is the one we've been using since I was a teen.
