Something like this would probably be my go-to: https://www.amazon.com/Golf-Ball-Retriever-/b?node=3411041

Any area I've cached, there have always been plently of caches that don't require a TOTT -- so no, you don't need one, but it might come in handy, depending on what you want to find.
Around where I live, probably the most common TOTT is a long pole to get caches down from trees. Don't exchange this for a ladder -- a lot of the caches are up in thin spindly trees growing on uneven ground. They're designed for you to get them with a pole, with both feet on the ground. You can buy golf ball retrievers for not too much money at a sporting goods store, these usually work well.
Other TOTTs I've seen are batteries for gadget caches or a UV flashlight. If you read the cache page, you should be able to get a sense of what you need. But every so often, a cache owner will get creative and make you use something you've never thought of before ;)
Had to check it out on Google Play: https://play.google.com/store/apps/details?id=de.westnordost.streetcomplete
That looks pretty cool! Love that you can play it like a game as a team. I need to try this out
Yes, there were two others you could get -- one at some low number of points, and another at 100 I believe
Yes! Beach clean-up are always a good time where I am. I've made some pretty strange garbage finds over the years -- keeps things entertaining when you find microwaves, kiddie pools, toilets and more in the woods!
I did not know they offered free trials -- that's awesome, glad you are enjoying it so far!
Cute! Was the cache inside on of the little houses?
Got to get them hooked early on!
I found a nano cache inside of a padlock once. The part where the key would go was drilled out, and replaced with a tiny cache container. Took me ages, awesome find.
I've gotten Tim Hortons gift cards for FTF before, that was pretty nice. Pins are also always cool to find
Good luck! Magnets always make me paranoid that I won't be able to put the cache back, but maybe it'll work for this one!
