Best inexpensive fishfinder for shipwrecks?

Exploring a bay area on a small boat with known shipwrecks and would like to buy an inexpensive fish finder and looking for opinions from fisherman. I assume some sort of side scan option and maybe something like a Hummingbird Fishin Buddy but I’ve never used one so not sure if they are any good for this type of use or should I look at something else?

Best inexpensive color fishfinder?

I am planning on getting my husband a fish finder for Christmas and would like suggestions on what would be the best to get. My budget is no more than $300 and I think I would like to get him a color, unless somebody convinces me it’s not necessary. He has a 14′ fishing boat and generally fishes rivers and reservoirs. Thanks so much!
