Have the 73CV at trolling motor and have 93SV at helm...both chirp models.

I notice their contours aren’t quite as detailed as say Navionics webapp In like creek channels and certain areas. To the point where I sometimes use my phone to find spots over the unit.

Will updating the maps fix this? Or is lakemaster or navionics chip compatible with these units?

My next question would be which garmin lake update do I buy if I went that route? I see different regions HD and then I see an all US lakes.

Anyways, just want the best contours I can get for my unit...all help is welcomed.

Thanks!

Garmin maps suck

G3 Ultra HD maps are very detailed with pics and sidevu screen shots. If your lake is included it is great. Lakemaster and Navionics are not compatible with Garmin units.

I have 3 9" and am going to upgrade soon.

also, have you tried changing the map view? they have the fishing/navigation etc. and it will change the view.

Yes I have...if I buy one download, can i load it on both of my units?

I would think so you have the same graph combo as I do. Are they networked? If so I would think you load on one and have it upload to both units.

Yeah they did, those are older units, I think the newer models have better maps.

I have a new 93SV UHD,...I had an old 93SV from about 5 years ago, There is no comparison the new unit
has a better map than my Lakemaster that I run side by side with my Helix 7.
The Garmin map is excellent. A friend of mine and I were talking about Lake Fork when it was being built and flooded,
he was here not me. He told me that few people know that there is a Coffer Dam that was built in Lake Fork, and how big it was and where it was,.....I went and looked, and it was no where to be seen on LakeMaster but was perfectly ourlined
on the Garmin.

If I update my maps to ultra hd, will I be equivalent?

No, I have the 73SV, as with anything tech theres something newer and better out within a year or even months. You can buy a lakevu card but the texas lakes are very limited.

My 2 93sv's are 4-5 years old. The maps look like someone gave a 6yr old the outline of lakes and said draw a bunch of squiggly lines. Not even close to what is there.

which map screen are you in?

navigation shows very few contours, fishing on my 2 93sv plus (non hd) do a good job on fork.

I am going to upgrade to the ultra maps soon tho, sounds like they are about the same as navionics platinum.

I wish garmin would let us buy a download for ea. unit by ser. number.


just dreaming. lol

My 93 SV UHD come with the LakeVu g3.
