This was from the VS-825sd a couple weeks ago when Jesse and I were running around the P-4 scour hole.
Note the 67.5 foot depth and how clear the water is.
Between the 825 and 625, there’s a lot of personal preference involved, but if you’re going to be a distance away from the monitor I would have to recommend the larger version. Just like a TV, bigger is better further away.
You’re best bet is to go to the store and compare brands side by side. What you’ll find on some cameras is they’ll take a 6 inch picture and stretch it to the 7″ monitor.
Side by side in the store, you see the MarCum picture will be clearer further away then any camera on the market today.
But don’t take my word for it. Check it out yourself.
