Lowrance H20 Handheld and Mapping

Question,
And this is far off maybe and I may not make alot of sense but I am going to do this as best as I can here.
Those units the H20, if i were to to take a pdf map and convert it into whatever file it takes to load mapping onto those units and saved it onto a card can I run lake maps of my own off a hand held?
We arent spoiled with Lakemaster out West like you are in the east so im trying to improvise…

Try this
Dr Depth mapping software

You can’t make your own using you own images on the h20, I used to have that unit. You can on the Garmin Oregons and possibly the Dakotas. I have done one myself. It’s not to hard to do.

awesome! this is going to be a HUGE help..

It would be soo sick of a flasher had a built in memory card to upload mapping right there, so you know where your hole is on that break, hump or weed flat. Eh? WINK WINK

SOMEONE, INVENT!
