I am not sure if this question belongs in the underwater photography forum or the snorkeling and freediving forum. Please be gentle. 
I am a snorkeler/freediver and very casual picture taker. On land, I lately have just been using my Nexus 6p phone. I used a Nikon Coolpix S210 on vacations from 2008-2015 (the battery door finally broke off) and was happy with--the zoom was easy to use, the speed seemed ok. I hated the Nikon Coolpix S3700 I got in 2016 to replace it. It was hard and took too long to make adjustments, use the zoom, seemed slower once the button was pushed. I sold it to Amazon just to get rid of it.
I am looking for something new to use snorkeling and free diving (shallow) that has an easy to use zoom, easy to adjust settings, is reasonably fast. I have not shot much video, so that is not a must.
I have looked online at reviews for the "best" this and that and remain confused. I need to get something for two snorkel trips we have this fall, to once in a lifetime spots that I want some image records of (Wakatobi and Fiji).
I would like to be in the $250 or under range but if that is not going to get the job done, would go higher. Also, I would like it of the camera was a reasonable all around one so I would not need to get a different camera for dry land.
I have seen references on Scubaboard to the Olympus TG-4 ($299 range) and see there is a new TG-5 coming out at a hefty increase ($450) but am not knowledgeable enough to evaluate the differences.
Really, I am such a newbie that I am looking for ease of use and reliability. But zoom is important to me.
Suggestions, please?
Many thanks!
