lowrance gps with lake map chip??

9 posts in this topic

this summer i bought a handheld lowrance ifinder expedition and the lake map chip... has anyone else used these on mille lacs.. are they accurate enough to easily put you on flats and rock piles?? i live in duluth and have found them fairly accurate here but not completely... i know there have been a few boating accidents this summer where people were navigating at night only by watching there gps and ran ashore (foolish)).....overall i love the thing but hope it's accurate on mille lacs especially???? laugh.gif

They are pretty tits on.

However, the lake is down at least 3 ft or better than what is says on the chip, so you still have to be careful.

Mid-lake structure and main shoreline breaks are really accurate, but there are a lot of shallow spots in the rocky areas close to shore that aren't identified on the chip (especially on the east side).

yes they are almost dead on. I was out there in june when water levels were not so bad and it was right on to what the vexilar was saying.

I even went to Myr Mar flat in a certain spot while a bunch of other boats were fishing as well alittle ways away. We started realing in fish and 2 guys yelled to find out why we were away from the crowd and what we were using. My reply was to let them know they were not even close to the flat if that was what they were looking for. LakeMaster RULES! I agree though, it is pretty accurate but as the water levels go down the depth readings on the maps will be off. The flats will be in the same place but depths are the only thing changing.

Some lakes are better than others. A lake like millacs will be updated more often than smaller ones. I have navionics hot maps 07, and so far it is pretty close on smaller lakes. Going to try millacs this weekend. How does that hand held work for you? To me it seems that there would be too much going on to hold something else.

They make mounting brackets for them so you can put it in just like a fish locator. If I'm not mistaken the one I have is made by RAM.

Oh, I see. I have a ram mount on my lowrance 525c. Those mounts are cool! You can move it where ever you want.

Just remember the warning that comes up each time you power your unit up. It says something like do not use this as your only navigational tool. I would never use and trust a GPS to navigate through unfamiliar area's. Once you have tested the area's in question it is a great tool. I know I love mine.

Very good point. I am still learning mine. Thinking of taking the class they offer. The book that came with doesn't have enough pictures, I can't understand words.

      I know this is an Ice Fishing thread, but I can't seem to find much information on ice condition on the lake or how the snow looks out there and on the trails. I live down in the Duluth area and was thinking about coming snowmobiling up there this next weekend. Seems the whole states in a stupid heat wave. But you guys had more snow than us before, was wondering if there's still enough to snowmobile.

      LOTS of traffic on the Hole In The Day access over the weekend.  It degraded noticeably from Saturday to Sunday.   There are two paths heading out.  The one going straight ahead has a bit of a ridge at shore that longer houses/low clearance vehicles might have a little trouble with.  The one to the right is angled and doesn't have the ridge but developed a hole at shore Saturday night.   I'm hoping it doesn't get any worse but probably will before the weekend.  We were planning on being out overnight before the contest but plans seem to be changing.  Especially since it was reported that a vehicle went through by Hunters Point over the weekend.  Hunters Point is on the Southwest side of the lake but makes my wife leary of taking out truck and house back out even on the Northeast end where the contest is.   Sorry for the bad news.  I'm still crossing my fingers and will check the access again this week.

      Very nice fish! Thanks for the heads up on the ice cleats. Do you know how the access is holding up with this warm weather ?
