It's this one I've just ordered... happy to spend £4/yr for the revs/hours info.
Impressions/test to follow.
Digital Hour Meter Tachometer Adjustable Resetable Job recall max rpm + service | eBay
Hi Fenlander the tach you linked looks identical to one the I owned 2 years ago.
Only lasted a season and a half and died last year.
Observations I made were that where the cable enters the body there is a small gap.
Also the rear of the unit casing is push in - as such pops in and out.
Likely to see water ingress also .
I mounted mine externally near the tiller so that I could read the RPM.
Despite it failing I've bought another tach identical.
I've siliconed the rear casing and around the cable entry point.
I'm thinking of putting it inside the cowling this season to keep semi out of wet stuff.
But TBH for all it costs I will probably velcro it on externally again so that I can observe my RPM.
They are cheap as chips - just hope the silicone makes it a bit more durable☺
