Here is a pic of the inside of that billet- CNC machined anodized aluminum case. I would prefer they put the screws in from the backside. Also, if you buy one, ditch that carbon zin c 9 volt battery! If you happen to leave the switch on and put the tach away, That battery will likely leak and corrode the insides along with the case. Better to use a quality alkaline or lithium 9volt
Yep, those are the only type that I use. They come with both a Tinnerman style push nut and a thicker,nylon
push on. They also have a very pronounced barb. Actually hold very well,snug with absolute minimal play.
I guess if that were not the case I would have installed a brass shim. Never a problem.

So if I take the guts out of a cheaper tack and then put them in a aluminum case. Does that mean I could get that much for a tack.
Or are they that great of a tack to warrant that kind of expense

Here's my take on tachs. Used to be you had to spend a lot to get an accurate tach that would work on an overcast day. That was before china cloned the circuitry. Nowdays tachs range in price from $15 - $150 and all work well with sufficient light. How accurate is my cheapo GT Power tach? Don't know but it can't be off by enough to make any difference for my purposes. I just use it to make sure an engine is pproducing the power it should and to richen the mix from peak. An error of +/- 50 rpms doesn't matter because it's a relative measurement. My cheapo tach doesn't work all that well in low light, like at dusk or dawn. That's fine, I can wait for the sun or shine a flashlight through the prop if I'm desperate.
PS, the GT Power tach is very small, lightweight and fits in a shirt pocket. If it dies it costs $15 to replace.

Wasn't but there is now. A piece of 1/2 mm urethane.
The fit is close, very little space for the battery to move. This case is SOLID! The older version was plastic and the cost was near the same.
Solid billet, CNC cut.

Give it a try
Probably cost you about $200 to duplicate the case, but you won't have the same guts when done!
This one takes solid readings from 6 feet away!
Like Isaid in the first post, I didn't NEED it. But I sure like having it.The 40 year old Heathkit that was my first tach works great! Far more stable than the current Chinese offerings to boot! The 30 year old original TNC is my first digital . I still prefer the analog meter .Then again, I never take a tach to the field .
An extremely high quality, excellent performing, durable level ,USA made device. Well worth the asking price imho. Just saw an older, used, plastic cased Fromec sell for $135 on RCG. It was snapped up very quickly .
I won't miss the Saito 100 in the least.

I would have no trouble using it in the rain
No trouble at all.
I fly in the rain too but can't recall the last time I needed a tach at the field , let alone needed one in the rain! More concerned with the transmitter.
Try a plastic baggie?
Keeps fuel off of electronics too.
When camping out on the motorcycle, I kept everything in plastic baggies. Watch, wallet, radios.
Especially in spring and winter.

I like the big scale on the Ace, I also modified mine so I can calibrate all scales accurately with a separate potentiometer. The original only had one pot and the calibration only good on one scale, at one point
Is it waterproof? Which one is?

I have had this one since the early 90's, most likely built in a house hold in Mo.,
Tom Runge farmed a lot of the circuit building out to local residents in Higginsville, Mo..
