Consol

[Ultimate Fly Fisher]

I have an older Sherwood Consol with Psig and a depth guage and a small timer at the top. I bought it used and now the battery has gone dead. What tool do you use to getinto the consol itself. It looks like a hex tool but I can't find one small enough at the auto stores. Is this a special tool and where do I get one. Sorry I don't have the model for this consol. Thank you for any advise.

No need to reply. While getting a closer look the guages at least the top two pop out from the consol. The Hex nuts turned out to be dummy/fake hex nuts. I was able to repair once I got them out of the consol.
