Oh my gosh...are we related somehow? 😄 You sound just like me. When I first purchased my D10 14 years ago I absolutely LOVED it and that's what got me hooked on taking pictures AND snorkeling. The pictures were amazing. However, after several of them dying on me, including batteries dying all the time, I learned years ago I needed one more camera as a back up and would carry 2 camera's with me. Eventually I would go on to purchase extra batteries to take along and extra chargers. I was PREPARED!!
Then I switched to Olympus Tough cameras. I started with the TG4, then I bought two TG 6 after I discovered the macro on it was to die for. Then I added a GoPro Hero 7 (which is probably the crappiest GoPro ever made but it was a Black Friday special I got for cheap) and now I have the GoPro 10. I still have some of my older Olympus camera's but my munchkin cracked the screen and can only be used on land. So, it just sits around now...as a just in case. I have so much equipment I bring along with me...chargers, batteries, straps, SD cards, filters, tripods, extensions. I go all out these days and I absolutely love it! It's my passion and I get so much joy in putting my reviews and video's together. I could do this full time for sure! Maybe some day. 😊
