A co-worker and I went detecting at a permission of his in the white sugar sand off US1 in Ft. Pierce where there's lots of 4-wheeling going on. (Ft. Pierce is home to a WWII training camp and the modern Navy Seal Museum. Click on this link for info. LINK. )
We went our separate ways at first. I doubled back after an hour or so and noticed him about 50' away. Had my head buried in a hole like an ostrich when I feel someone calling and it was him hollering something that sounds like "grenade". I think my stupid hearing is really distorting things when I realize he did say "Grenade".

We go back to his hole and on the edge of it is this sugar-coated dark object. He said he didn't know what it was at first but his machine read 85-87. (At this point, I'm thinking he's one lucky Duck and needs to buy some lottery tickets .... today.)

While I back a little further away he gets a water bottle and dribbles it on the piece. After he can see it more clearly he announces "it is cast" and proceeds to carefully pick it up while I hold my ground. (Someone needs to be a witness if something goes awry.:laughing7:)
He's right of course so we rinse it some more. We realized there were opposing "slits" on each side filled with sand and after more water, we see these slits actually go all the way through. All I can think is that these slits allowed this to be placed on a belt, maybe for training? It weighs 4 lbs and is brass or bronze based on the "yellowish" color showing through the nick in the outer rubber coating (last image).

Anyways, here are some more images. (Bud doesn't post and said it was ok to share the find.)

Brass is shown through the soft, pliable rubber coating in the image above.

We're not sure if this might have been some kind of training tool that may have been left behind during the WWII heyday or if it's something modern. Hoping someone here might have some insight to share.

Thanks for looking and adding any insight you have.

Especially when he noticed there was no longer a pin in it and before he realized it was cast.

It was odd because it took about 30 seconds for the caution to completely wear off even after we knew it was safe. Kind of like waiting for the lightning to strike nearby when you're out in a storm!!

No wonder your heart raced, but it's not a (practice/training) grenade. It's a diving belt weight with a rubberised coating. You can get them in a number of novelty shapes, including hand grenades. Here's an auction listing for a similar one:

Here's another that someone found at a fleamarket and posted on a militaria forum (also wrongly believing it to be a practice grenade) that shows the form better:

Glad it worked out ok. Know that feeling, Very different from when you find a coin, jewelry, or a great artifact. Here's how mine ended up:

Thanks everyone for chiming in.

Special thanks to Redcoat for that info, images, and links. I was thinking it possibly went on a dive belt as well but couldn't figure out why it was a mile from the beach unless it was used for training in these sand dunes, far from the beach. (My imagination let me visualize navy seal training in WWII!)

Maybe it was in one of the 4-wheelers using these trails and bounced out?
US1 is on the other side of that rise.

ps. Sanddog, glad yours turned out well. I remember one in the past year or so making the news. Was yours last year? (Avalon Park?)

No, found just a little south of South Jetty Park, Ft. Pierce. April 11 this year. See the Legend threads in the Nokta/Makro Forum.
