I absolutely overlooked that the Beach Hunter 300 was a VLF machine and not Pulse, thanks for mentioning that.
I have a Surfmaster PI Dual Field that I use when I dive and also have the Beach Hunter ID 300, I have an opportunity to get rid of the 300 and purchase the TDI.
I think that TDI sounds like a little better machine for walkin around on the beaches, looks like it will be fun on the YT videos anyway.
