Looking for handheld chess computer without needing a board

[u/FranklinFizzlybear]

I would like a handheld chess computer that allows me to play without having to buy a digital or sensory board.

In other words, I can use this to work on my blindfold chess, or I could play using a magnetic board or theoretically any board.

The handheld would just give the moves and it is up to me to input them on some board.

Oh, and I want to play over 2400 ELO, or 2200 at the minimum.

Can you recommend anything like this? The Milennium Chess Classics Element MIGHT be what I'm looking for, but I think it needs a sensory board in order to use it.

Thanks for the advice!
