Default Garmin GSD22 Sounder in DEEP Water???

Who has used the GSD22 sounder module in deep water, below 200 feet??

I LOVE the sounder, and find it works just fine in less than 200' of water. Can see everything and all bottom detail just fine.

Yesterday I took it out to the canyons (Hudson) for the first time, and was in 1000' + water depth. I found below 200 or 300', it began to loose detail, and became very "fuzzy" on the display. By fuzzy I mean it looked like a snow storm on the screen, but it did still hole bottom ok. I do not know if there was any bait in the water, as it did not show any, BUT, there was no life out there, so it's possible there was none, hard to say.

BUT, the sounder definitely did not perform all that great in the deep water. I've herd a few comments about this from a few other users, I'd like to get some details.

I'm sending Garmin tech support the info....

Were you running on 200 or 50 hZ? 50 will penetrate better but you will lose detail.

Ctoolman,
In 1000', do you have the same clarity as you do at 100'?


Glen,
What do you have between 200' and 1000'? Same question as above, do you get the same clarity at say 600 as you do at 200?

Tried both separetely and Dual freq split screen to compare. About the same "detail" with 50 and 200 side by side in split screen, in 800' of water.

Birdman maybe it's not the sounder, but the transducer. Is the transducer a tilted thru hull? Was it installed right? I would think that if everything is in correctly. It should go past 1000'ft. Send me a PM and I will help you out.

I was just out deep swordfishing and could read bottom detail in over 2000 feet with the unit set to 50 kHz. It works well out to 600 feet in 200 kHz. I have it coupled to an old Furuno (Airmar) B44 flush mount transducer. I use an Airmar crossover cable to mate the Furuno xducer cable end to the GSD22 box.

Transducer is tilted, and installed PERFECT. And again, at 100', I can see quarter on the bottom, and everything inbetween. and I'm not talking about running, so it's not a "dirty water" issue. This was whle trolling. The ducer is a 20 degree tilted, it installed on a 19 degree hull, and it's installed in front of all running gear, and there is nothing (thru hulls, strakes, intakes,..) in front of it. Actually, it works great when running.

Not a ducer issue. It's a software issue. However, open to ideas. PM coming....!!

The important question is...

Did you see a THERMOCLINE? [img]../jscripts/tiny_mce/plugins/emotions/images/smiley-laughing.gif[/img]


Did you really go to the Hudson after I spoke to you? I tried to raise you again, because I spoke to a couple of guys that were about 35 off and they were getting pounded with winds out of the SE 20+ knots!

Yeah, did the Hudson, no fish, dead as a door knob. Ran into Finseeker out there... Yep, was a bumpy road on way out, but Machria ran like a horse thru it!

Ctoolman,
In 1000', do you have the same clarity as you do at 100'?


Glen,
What do you have between 200' and 1000'? Same question as above, do you get the same clarity at say 600 as you do at 200?

yes...

Fella's, Im not sure you are reading bottom up to 1500ft plus?? I lose bottom at 1000 or so and have a 4212, GSD22, Airmar B164. I called airmar and garmin abotu losing bottom at 1000ft, the guy at airmar acted like I was a fool. Saying that transducer will not read much over 1000 feet maybe to 1200 if conditions were perfect. He said to read up to 2000ft you really need to buy a 2kw ducer........take it for what it's worth. If your loosing bottom at a grand or so, thats normal. The problem is NOT marking a damn fish all day long in 300 plus feet of water.

ktrain,
Agreed. Actually, I was holding bottom just fine in 1200' of water, that was not a problem and I too thought that part was pretty good. As they noted, that is about the range of a 1000watt's.

BUT, what I am "concerned" about is the detail (or lack of) I saw between 300' and 1000', as you also seem to have noticed. My only issue is, I was only out there 1 day for a few hours and I was busy tryin to fish, find fish..., so I didn't have a hole lot of time to play with it, take pics......

So I'd like somebody with MORE experience to post pics, info, settings..... that we can send to garmin. I've already sent them an email on it, but didn't have much info for them.

You guys telling me I should have gone with Lowrance? (I am impressed with the fishfinder on the Lowarance LXC113HD)

I can pick up the bottom in 2000'+ all day long, but it still shows nothing in between. never has in over 1 year of use.

B-faithful,
No, cause in your case (aka shallow water), it works GREAT. I've been very happy with it in water below 200', no problem at all, nice clean detail..... I have only had the problem this past sunday in 600, 800 and 1000' of water. And like I said, I did not play with it a whole lot.

BUT, I will say this, the HD 24" Radar on this unit is the SHIIIIIIIIIIITTTTTTTTTTTTTTTTTTTTTTT!!! The HD radar is amazing, I can't beleive the stuff I'm picking up miles away. I am getting returns on a piece of wood (2' long 2x4) floating on the surface, 1 miles away. SWEEEEEEET!!!!

I just spoke to Garmin about this problem. They had NOT herd of this problem previously (so they said). I gave them al my info, but they need pics, examples, and more complaints before they are going to work on it!!

Send tech support email, details..... pics if possible.
