In RepeatDetector, override the Description property to return "Detects repetitions"

So I am not having trouble solving this problem but this challenge is having us use override in the public field, I wanted to know if it is more appropriate to use new here instead of override since the field is public please and thank you!!

RepeatDetector.cs 
namespace Treehouse.CodeChallenges
{
    class RepeatDetector : SequenceDetector
    {
        public new string Description => "Detects repetitions";
        public override bool Scan(int[] sequence)
        {
            if(sequence.Length < 2)
            {
                return false;
            }

            for(int i = 1; i < sequence.Length; ++i)
            {
                if(sequence[i] == sequence[i-1])
                {
                    return true;
                }
            }

            return false;
        }
    }
}
SequenceDetector.cs 
namespace Treehouse.CodeChallenges
{
    class SequenceDetector
    {
        public string Description => "";

        public virtual bool Scan(int[] sequence)
        {
            return true;
        }
    }
}
