Just one thing to remember, the small transducer you clip to the 'screen does have a tiny battery sealed in it (last about 5 yrs)
If you log into your account it will tell you if it needs replacing & they will send you a new one BUT YOU HAVE TO REQUEST IT.
Worth noting if you need it to be ready for later this year but have not used it for ages
Just ordered my new one 5 Euro postage.
