Default Garmin 741XS user info thread

This is a thread dedicated to the new Garmin 741XS. Its a really great machine and it does far more than I even know but like most it has a few quirks. I thought Id start a thread for everyone to list/compare the things they like or dont like, tips on functions, glitches, and update info and compatibility with other components. Not only will it help us owners but might help out folks considering buying one.
Really do love this machine. So much so that I have 3 of them, one on inshore boat and two on my offshore rig. Best plotter on the market IMO. Great connectivity with just about anything, has held up well, weather option is fantasic, music management, love the side-scan.
Had a small issue with the power button and they actually replaced the unit for me. Another time I think I shorted it out by putting a damp SC card in it. Other than this its been great.

Latest software update for the 741XS from Garmin:

I'm sure this one is WAY outdated...

Great thread on Fusion stereo hook up and bluetooth on the 741

i just installed one on my dads boat with a tm150m and we were sounding down to 1500 feet (not fish finding) so far that is as deep as i have tried and interestingly enough we split the frequency and a 140 pulse would not pick up bottom only chirp, i didn't install the transducer but my dad did and not sure if it's dirty water or just the transducer itself but it loses bottom after 18 mph.

Do you guys find the screen to be too small on the 741?

Do you find the 741xs worth the extra money over the 740s?

I had the 740 and for the money it was a great machine, especially what they cost now. Love that machine. I upgraded to the 741 mostly for the CHIRP sonar which I am thus far quite unhappy with. The rest of the machine however is great. It holds 5000 waypoints, updates the plotter faster, has 2 micro SD cards, and has lots of really cool functions when linked in with other things like the stereo. I have the XM stereo with the weather package and love it.
Not only does is show weather that you can use to avoid it (boat radar doesnt work that good due to the boat moving) but it pops up marine warnings on the screen with a beep which has helped me out several times. On the Wx screen you touch a bouy icon and itll give you real time data from that buoy, which is really helpful.
Perhaps my favorite thing is that the XM music screen comes up on the 741 showing every song thats playing on every station and you just touch the screen and that song starts playing. Im just now adding the Fusion stereo with Bluetooth and looking foreward to having all my Ipod song available on the screen as well.
All of that helps me by not having to open my overhead instrument box (where the stereo deck is) and having all my stuff fly out to change the channel.
After a bit of practice and a note sheet, I have become pretty good at transfering numbers to cards/my laptop and blanking the machine when its in for service or anywhere anyone has access to the unit.

Default 741xs

Gulfguide - what don't you like about the chirp sonar?

i just installed one on my dads boat with a tm150m...the transducer loses bottom after 18 mph.
derrain - any more info on this. Due to thru-hull mounting limitations on my new boat, I was about to order a TM150M next week.

This might help:

I was also wondering if the screen would be too small on the 741xs with the "virtual buttons" taking up space on the bottom of the display.

My CHIRP sonar is not what it was cracked up to be. The standard Furuno next to it is far better. Its not very good at showing bottom features. It shows fish in the column pretty good but ledges and small wrecks dont show up that great and just kinda blend into the bottom. I dont even use it now and I dropped like $1200 on the oversized CHIRP transducer. If it were me, i wouldnt do it again.
And you can run the sonar with no buttons on the screen if you want.

Ill start it off by asking if anyone else has had a problem with the units' power button. Lately mine has worked great but when i turn it off it wont come back on when i push the power button. Sometimes if I push it 3 times then hold it'll come on but most it simply wont come on. I have figured out that if i disconnect the power cord on the back of the unit then put it back on (essentially a re-boot) it will come up first press of the button. Is it just me or have others had the same problem?

I have done both of the recent software updates but no no avail.
I've had the same power button issue.

Thank Krab! Knowing someone else has the same issue might make me refrain from rerigging some stuff that doesnt need it. Im going to give Garmin a call and will report back what they say. I does seem like an issue with the unit not my wiring.

im not 100% percent sure as stated in previous post about transducer placement. he only had the boat out of the water for a couple day's and i was in camp when he did the install. It might be the transducer itself or the actual placement. We did however mark salmon really well in 250' feet of water. The TM250 for a cheeper transducer actually surprised me. I have the gsd 26 with a tm 265lh and it wasn't that far off and it also was able to sound down to 1500 feet ( maybe further didn't try). I was really surprised that the chirp end of things actually did what it was suposed to do it sounded deeper than pulse with lest energy. We were in a rush had to pick up crew but maybe next time i will take some pictures and who know's maybe a couple of air bladders.

This may send some guys into a tizzy and im a garmin fan, but I just feel like the quality (look and feel) of the 740xs is not up to garmin standards. I dont however have any first hand rxp with the unit. Just an observation.

It actually uses more energy than pulse. Pulse length isn't tied to resolution like pulse sonar, so it uses longer pulses and can pulse more frequently. Peak power for short periods is higher on pulse.

And you can run the sonar with no buttons on the screen if you want.
The reason why you are not happy with CHIRP for structure is because the sounder technology is so good it's shown the targets in a much more correct scale than a fixed frequency pulse sounder. At larger depths fixed frequency sonar use long pulse lengths to be able to transmit sufficient energy into the water, long pulses give bad vertical resolution but it also draw very small targets as large objects on the screen. For a CHIRP sonar the vertical resolution should theoretically be the identical for all ranges, how it actually is differs between the implementations, but all CHIRP sounders draw small targets at larger depths much smaller than a fixed frequency sounder. If even when zoomed in the CHIRP sounder is drawing small bottom targets so small it's difficult to interpret, just switch to a fixed frequency and it will be drawn much larger.

The two screen shot below from a 527xs with CHIRP in the left half and 155kHz in the right half is illustrating the difference between CHIRP and fixed frequency very well.





In this screen shot the huge advantage of CHIRP resolution is shown. First I was running fixed frequency pulsed mode and in the middle I switched to CHIRP. As Gil commented the first time I posted this image the fish in fixed frequency pulsed mode looks like Pac Man's.

Heres a couple pics I took the other day. Both at the time, same pass over the same spot. The Furuno is standard sonar on high Freq, the Garmin is on CHIRP. Granted, the pics arent great and one is a 10 inch screen vs. a 7 inch, but both at the same small wreck, in very similar range settings. Ill take a better shot next time but the difference here is common for me and thus far Im not a fan of my CHIRP.

I just had mine installed a week ago but I did notice a few times it was hard to turn on. It would start loading and then turn off. If you find out what the issue is please let us know.

I called Garmin today about the power button issue. Garmin keeps track of issues but they didn't have this one. If you are experiencing this problem it is important to contact Garmin and report the issue so they know the extent of the problem.

Abbor, What were the TVG settings?
In the upper water column the bait fish seen to be in the same relative scale, however in the lower column they are smaller in Chirp compared to fixed freq. It seem like increasing the TVG in chirp would correct this?
