Garmin - 7 CV - Waypoint Where??

[Bartableman7]

I'm brand new to using marine electronics.  The image is beautiful in down scan. But...when I mark a Waypoint with my unit am I marking the position of the boat or what I've already passed over? If I'm marking the boat then I must be off by numerous feet from the rock piles.  I don't want to waste casts at nothing and I want the Waypoints to help with accuracy.  Thanks for any ***.

Your marking the current gps coordinates of your unit by default. 

 

Your unit will most likely allow you to mark specific targets you see on the sonar images. You'll just need to read the manual or download it if you don't have one. Probably will take a few extra seconds once you get the hang of it.

You can use the cursor on your graph to mark a location you've already passed over and it will put a waypoint at that point on your map.

Aside from this question, how do you like the 7cv? Is it your first and is it easy to use? hows the echomap?

My step-dad bought a Echomap 93sv CHIRP (non plus unit) for a walleye trip he's leaving for Friday. He hooked it up last week and I finally talked him in to meeting me at the boat launch. To be honest I just wanted to play with it! I've played with them in the stores and a Helix unit my brother in-law bought 3 years ago. 

 

This was the first time I've used one on the water. It was awesome! The only change we made so far was to slow the scroll speed down. This unit was the first new tech. expensive either of us had used. I started out reading the manual and he grabbed my rod I brought that had a bladed gig tied on and was fiddling around with that and quickly noticed he could see it in traditional 2d which he liked because he does a lot of jigging while walleye fishing. 

 

After messing around with little things here and there I noticed there were two pot holes on the map of the lake that went from 30-35' to 56' in the middle. I had him go over this pot hole, I switched to DV and SV and could clearly see a nice school of fish suspended 20-25' over this pot hole! I wasn't expecting to see them without adjusting the settings. This was just on auto. Needless to say he was pretty impressed too. All of our lakes are natural and most are pretty featureless and mucky bottoms so I didn't expect to see a whole lot in the form of structure. Plus this lake is about 15-20 acres in the little town I grew up in. 

 

We spent 2.5 hours on the lake messing with this unit, a little fishing, some talking, and mostly staring at the screen. I wish we could be spent more time out there but he had things to do. I could've spent the entire day out there getting acquainted with the 93sv. 

 

I was really impressed with how easy it was to use. I was also impressed with the images we saw, like I mentioned before the only change we made was to slow the scroll speed to medium, everything else was auto. I'm keeping my fingers crossed that very very soon I'll be upgrading boats and picking a couple of these up because they're well worth the money!

Just wait until you mess around with SV....

I messed with it a little. That's when I originally saw the suspended school of fish. I was showing him that we were coming up to the pot hole because the bottom was dropping out, and I saw a bunch of 'glowing' dots and said look at the school. We looked over on the DV and saw the same thing. 

 

I've been researching the Echomap units for a year now so I'm kind of familiar with them and their capabilities. He on the other hand doesn't know a whole bunch about them except from what I've told him about the Echomap units and any down and side seeing sonars units for that matter. So he just turned it on and had the mapping and 2d on the screen. It's his unit so I gave him time, but I couldn't take it anymore and took over. ? I didn't get the chance to go around any docks to 'look' under them. 

 

Like I said hopefully soon I'll have a bigger boat and a couple of these because the short time I had with it, it was a blast! I want to go around a look for ice shanties that fell victim to an early spring and irresponsible owner. Surprisingly enough I have the wife very intrigued, so my sales pitched worked. All I had to do was show her some screen shots and told her we can look for things like shanties and she was sold! Thank God! LOL
